Health care practitioners, such as nurses and physicians, use various types of health-care equipment to assist with the task of providing health care to a patient, also referred to herein as a health-care recipient. Some health-care equipment, referred to as single function equipment, is designed to perform a particular function, such as temperature measurement. Some health-care equipment, referred to as multi-function equipment, is designed to implement the performance of more than one function, such as temperature measurement and blood pressure measurement.
Physiological parameter monitoring platform devices are multi-function equipment that monitor physiologic data from one or more patients. Physiological parameter monitoring platform devices typically provide a user interface to display physiological data corresponding to particular functions. User interfaces for some physiological parameter monitoring platform devices often allocate space for display of particular functions whether the particular functions are being monitored or not.
One aspect is a method for configuring a presentation of physiological data for a patient. One or more physiological sensor modules are identified that are connected in a physiological parameter monitoring device. After the one or more physiological sensor modules are identified, the physiological parameter monitoring device is configured so that one or more display areas are allocated on a display screen of the physiological parameter monitoring device for displaying physiological data for the patient. A separate display area is allocated for each identified physiological module. One or more additional physiological sensor modules are detected that are connected in the physiological parameter monitoring device. After the one or more physiological sensor modules are detected as being connected, the physiological parameter monitoring device is automatically configured to include one or more additional display areas on the display screen for displaying physiological data for the patient. A separate additional display area is allocated for each of the additional physiological sensor modules that is connected.
Another aspect is a method for reconfiguring a physiological parameter monitoring device from a first workflow to a second workflow. On the physiological parameter monitoring device, physiological data is obtained from a patient according to the first workflow. A determination is made that a first physiological sensor device is being used with the physiological parameter monitoring device. As a result of determining that the first physiological sensor device is being used with the physiological parameter monitoring device, the physiological parameter monitoring device is reconfigured to the second workflow. Physiological data is obtained from the patient according to the second workflow.
Yet another aspect is a method for viewing physiological data on a display screen of a physiological parameter monitoring device. On the display screen, first physiological data is displayed for a patient at first time intervals. The first physiological data is displayed in tabular form. An alarm is received at the physiological parameter monitoring device. The alarm occurs at a time within one of the first time intervals. As a result of displaying the alarm, a column of physiological data is displayed corresponding to the time at which the alarm occurred. The column of physiological data corresponding to the time at which the alarm occurred is selected. As a result of selecting the column of physiological data corresponding to the time at which the alarm occurred, second physiological data is displayed for the patient at second time intervals. The second time intervals are shorter than the first time intervals.
Yet another aspect is a method for generating a warning at a physiological parameter monitoring device. A determination is made that a respiration sensor device is attached to the physiological parameter monitoring device. When it is determined that the respiration sensor device is attached to the physiological parameter monitoring device, a warning message is displayed to a user of the physiological parameter monitoring device.

The network 108 is an electronic communication network that facilitates communication between the client devices 106 and the between the client devices 106 and the interface system 104.
An electronic communication network is a set of computing devices and links between the computing devices. The computing devices in the network use the links to enable communication among the computing devices in the network. The network 108 can include routers, switches, mobile access points, bridges, hubs, intrusion detection devices, storage devices, standalone server devices, blade server devices, sensors, desktop computers, firewall devices, laptop computers, handheld computers, mobile telephones, and other types of computing devices. In various embodiments, the network 108 includes various types of links. For example, the network 108 can include wired and/or wireless links.
Furthermore, in various embodiments, the network 108 is implemented at various scales. For example, the network 108 can be implemented as one or more local area networks (LANs), metropolitan area networks, subnets, wide area networks (such as the Internet), or can be implemented at another scale.
The EMR system 102 is a computing system that allows storage, retrieval, and manipulation of electronic medical records. As used herein, a computing system is a system of one or more computing devices. A computing device is a physical, tangible device that processes data. Example types of computing devices include personal computers, standalone server computers, blade server computers, mainframe computers, handheld computers, smart phones, special purpose computing devices, and other types of devices that process data.
Each client device in the set of client devices 106 is a computing device. The client devices 106 can provide various types of functionality. For example, the set of client devices 106 can include one or more PMP devices (such as the PMP device 200). In addition, the set of client devices 106 can include one or more desktop, laptop, or wall-mounted devices. Such wall-mounted devices can have similar functionality to the PMP device 200 but are stationary instead of portable.
In addition, the set of client devices 106 can include one or more PMP devices. Such monitor devices can display representations of physiological parameters. A monitor device could, for example, be used by a clinician to monitor the physiological parameters of multiple patients at one time. Such monitor devices are typically not wall mounted.
The client devices 106 can communicate with each other through the network 108. In various embodiments, the client devices 106 can communicate various types of data with each other through the network 108. For example, in embodiments where the set of client devices 106 includes a set of PMP devices and a monitor device, each of the PMP devices can send data representing measurements of physiological parameters of patients to the monitor device. In this way, the monitor device can display representations of physiological parameters to a clinician.
The interface system 104 is a computing system that acts as an interface between the EMR system 102 and the client devices 106. In some embodiments, the interface system 104 is a CONNEX™ interface system from Welch Allyn of Skaneateles Falls, N.Y., although other interface systems can be used. Different EMR systems have different software interfaces.
For example, the EMR system used by two different hospitals can have two different software interfaces. The interface system 104 provides a single software interface to each of the client devices 106. The client devices 106 send requests to software interface provided by the interface system 104. When the interface system 104 receives a request from one of the client devices 106, the interface system 104 translates the request into a request that works with the software interface provided by the EMR system 102. The interface system 104 then provides the translated request to the software interface provided by the EMR system 102. When the interface system 104 receives a response from the EMR system 102, the interface system 104 translates the response from a format of the EMR system 102 to a system understood by the client devices 106. The interface system 104 then forwards the translated response to an appropriate one of the client devices 106.
The client devices 106 can send various types of data to the interface system 104 for storage in the EMR system 102 and can receive various types of data from the EMR system 102 through the interface system 104. For example, in some embodiments, the client devices 106 can send measurements of physiological parameters to the interface system 104 for storage in the EMR system 102. In another example, a monitor device can retrieve past measurements of physiological parameters of patients from the EMR system 102 through the interface system 104.
A temperature measurement module 212 is accessible from the front side of the PMP device 200. A SpO2 module 214 and a non-invasive blood pressure (NIBP) module 216 are accessible from a left hand side of the PMP device 200. An upper handle portion 220 enables the PMP device 200 to be carried by hand.
A front side of the PMP device 200 includes a display screen 218 and an outer surface of the temperature measurement module 212. The temperature measurement module 212 is designed to measure the body temperature of a patient. As used in this document, a “module” is a combination of a physical module structure which typically resides within the PMP device 200 and optional peripheral components (not shown) that typically attach to and reside outside of the PMP device 200.
The temperature measurement module 212 includes a front panel 212a. The front panel 212a has an outer surface that is accessible from the front side of the PMP device 200. The front panel 212a provides access to a wall (not shown) storing a removable probe (not shown), also referred to as a temperature probe, that is attached to a probe handle 212b. The probe and its attached probe handle 212b are tethered to the temperature measurement module 212 via an insulated conductor 212c. The probe is designed to make physical contact with a patient in order to sense a body temperature of the patient.
A left hand side of the PMP device 200 includes an outer surface of the SpO2 module 214 and an outer surface of the NIBP module 216. The SpO2 module 214 is a HCE module designed to measure oxygen content within the blood of a patient. The NIBP module 216 is a HCE module designed to measure blood pressure of a patient.
As shown, the SpO2 module 214 includes a front panel 214a. The front panel 214a includes an outer surface that is accessible from the left side of the PMP device 200. The front panel 214a includes a connector 214b that enables a connection between one or more peripheral SpO2 components (not shown) and a portion of the SpO2 module 214 residing inside the PMP device 200. The peripheral SpO2 components reside external to the PMP device 200. The peripheral SpO2 components are configured to interoperate with the SpO2 module 214 when connected to the SpO2 module 214 via the connector 214b. In some embodiments, the peripheral SpO2 components include a clip that attaches to an appendage of a patient, such as a finger. The clip is designed to detect and measure a pulse and an oxygen content of blood flowing within the patient.
As shown, the NIBP module 216 includes a front panel 216a having an outer surface that is accessible from the left side of the PMP device 200. The front panel 216a includes a connector 216b that enables a connection between one or more peripheral NIBP components (not shown) and a portion of the NIBP module 216 residing inside the PMP device 200. The peripheral NIBP components reside external to the PMP device 200. The peripheral NIBP components are configured to interoperate with the NIBP module 216 when connected to the NIBP module 216 via the connector 216b. In some embodiments, the peripheral NIBP components include an inflatable cuff that attaches to an appendage of a patient, such as an upper arm of the patient. The inflatable cuff is designed to measure the systolic and diastolic blood pressure of the patient, the mean arterial pressure (MAP) of the patient, and the pulse rate of blood flowing within the patient.
The PMP device 200 is able to operate within one or more workflows. A workflow is a series of one or more tasks that a user of the PMP device 200 performs. When the PMP device 200 operates within a workflow, the PMP device 200 provides functionality suitable for assisting the user in performing the workflow. When the PMP device 200 operates within different workflows, the PMP device 200 provides different functionality.
When the PMP device 200 is manufactured, the PMP device 200 is configured to be able to operate within one or more workflows. After the PMP device 200 is manufactured, the PMP device 200 can be reconfigured to operate within one or more additional workflows. In this way, a user can adapt the PMP device 200 for use in different workflows as needed.
In various embodiments, the PMP device 200 operates within various workflows. For example, in some embodiments, the PMP device 200 can operate within a monitoring workflow or a non-monitoring workflow. Example types of non-monitoring workflows include, but are not limited to, a spot check workflow and a triage workflow.
In example embodiments, the names for the workflows can be defined by the user. For example, the user can rename a “triage workflow” as “ED 3 North” or any other nomenclature as desired to provide more context to the user.
When the PMP device 200 is operating within the monitoring workflow, the PMP device 200 obtains a series of measurements of one or more physiological parameters of a single monitored patient over a period of time. In addition, the PMP device 200 displays, on the display screen 218, a monitoring workflow home screen. The monitoring workflow home screen contains a representation of a physiological parameter of the monitored patient. The representation is based on at least one measurement in the series of measurements. A representation of a physiological parameter is a visible image conveying information about the physiological parameter.
For example, when the PMP device 200 is operating within the monitoring workflow, the PMP device 200 can obtain a blood pressure measurement of a single patient once every ten minutes for six hours. In this example, the PMP device 200 displays a monitoring workflow home screen that contains a representation of the patient's blood pressure based on a most recent one of the temperature measurements. In this way, a user of the PMP device 200 can monitor the status of the patient.
When the PMP device 200 is operating within a non-monitoring workflow, the PMP device 200 obtains a measurement of one or more physiological parameters from each patient in a series of patients. In addition, the PMP device 200 displays a non-monitoring workflow home screen on the display screen 218. The non-monitoring workflow home screen contains a representation of the physiological parameter of a given patient in the series of patients. The representation is based on the measurement of the physiological parameter of the given patient.
In one example, when the PMP device 200 is operating within a spot check workflow, the PMP device 200 obtains blood pressure measurements from a series of previously-identified patients. In this other example, the PMP device 200 displays a spot check workflow home screen containing a blood pressure measurement of a given patient in the series of previously-identified patients. In this way, a user of the PMP device 200 can perform spot checks on the blood pressures of patients who have already been admitted to a hospital.
As used in this document, a patient is a previously identified patient when the PMP device 200 stores information regarding the identity of the patient. In another example, when the PMP device 200 is operating within a triage workflow, the PMP device 200 can obtain a single blood pressure measurement from each patient in a series of unidentified patients as the patients arrive at a hospital. In this example, the PMP device 200 displays a triage workflow home screen containing a representation of the patients' blood pressure based on the single blood pressure measurements of the patients. In this way, a user of the PMP device 200 can perform triage on the series of unidentified patients as they arrive. As used in this document, a patient is an unidentified patient when the PMP device 200 does not store information regarding the identity of the patient.
The monitoring workflow home screen is different than the non-monitoring workflow home screen. Further, as discussed below, the navigation options associated with the different workflows allows for efficient monitoring based on the environment in which the device is used. In various embodiments, the monitoring workflow home screen is different than the non-monitoring workflow home screen in various ways. For example, in some embodiments, the monitoring workflow home screen includes at least one user-selectable control that is not included in the non-monitoring workflow home screen. In other embodiments, a representation of a physiological parameter in the monitoring workflow home screen has a different size than a representation of the same physiological parameter in the non-monitoring workflow home screen.
The PMP device 200 is functionally connected to one or more sensors that enable monitoring of at least one physiological parameter that is associated with a patient. Typically, each sensor is physically attached to the patient while the PMP device 200 is operating within the monitoring workflow. These sensors include a temperature probe, a SpO2 clip, and a NIBP blood pressure cuff that are each attachable to the PMP device 200 as described above.
As shown in the example of
The device status area 312 contains data regarding a status of the PMP device 200. In the example of
The navigation area 319 includes a home tab 318a, a patients tab 318b, an alarms tab 318c, a review tab 318d, and a settings tab 318e. Collectively, the home tab 318a, the patients tab 318b, the alarms tab 318c, the review tab 318d, and the settings tab 318e are referred to herein as the screen tabs. Selection of screen tabs 318b-318e causes substitution of the monitoring workflow home screen 300 with another screen associated with the screen tabs 318b-318e. For example, the PMP device 200 displays a patient screen when a user selects the patients tab 318b. When the PMP device 200 displays a screen other than the monitoring workflow home screen 300 and a user selects the home tab 318a, the PMP device 200 displays the monitoring workflow home screen 300.
The parameter reporting area 314 includes one or more parameter reporting frames. Each of the parameter reporting frames contains a representation of a different physiological parameter a patient. The representations are based on one or more measurements of the physiological parameters of a monitored patient. In addition, each of the parameter reporting frames contains an alarm reporting area. The alarm reporting areas specify upper alarm limits and lower alarm limits for the physiological parameters. The upper alarm limits and the lower alarm limits define the alarm ranges for the physiological parameters. Alarms associated with the physiological parameters are active when measurements of the physiological parameters are outside the alarm range for the physiological parameters.
In the example of
The NIBP frame 314a contains a representation of the blood pressure of the patient. The representation of the blood pressure of the patient is based on one or more measurements of the blood pressure of the patient. In various embodiments, the NIBP frame 314a contains various representations of the blood pressure of the patient. In the example of
An NIBP alarm status area 322c is located at the right side of the NIBP frame 314a. The NIBP alarm status area 322c specifies an upper alarm limit and a lower alarm limit for the patient's systolic blood pressure and an upper alarm limit and a lower alarm limit for the patient's diastolic blood pressure. The upper alarm limit and the lower alarm limit for the patient's systolic blood pressure define a systolic blood pressure alarm range. The upper alarm limit and the lower alarm limit for the patient's diastolic blood pressure define a diastolic blood pressure alarm range. An alarm associated with the patient's blood pressure is active when the patient's systolic blood pressure is outside the systolic blood pressure alarm range or when the patient's diastolic blood pressure is outside the diastolic blood pressure alarm range
The NIBP frame 314a also contains a NIBP cuff inflation start/stop button 322a. The NIBP cuff inflation stop button 322a is labeled with the text “START.” The NIBP frame 314a also contains a NIBP automatic interval timer 322b. The NIBP automatic interval timer 322b is located between the diastolic blood pressure value and the NIBP alarm status area 322c. Selection of the NIBP cuff inflation button 322a starts and ceases inflation of the NIBP cuff and toggles the label of the NIBP cuff inflation button 322a to display the relevant status text (i.e., “START” or “STOP”). As used herein, a user selects a button or control when the user provides input to the PMP device 200 that specifies the control. For example, a user can select a control by pressing the control, by pressing another button while the control is highlighted, or by another means. Selection of the NIBP cuff inflation button 322a (now labeled the “Start” button) restarts inflation of the NIBP cuff and toggles the label of the NIBP cuff inflation stop button 322a to display the (“Stop”) text. The NIBP automatic interval timer 322b indicates an amount of time remaining before the next scheduled inflation of the NIBP cuff. Additionally, a user can determine the age of the current NIBP reading on the NIBP frame 314a by subtracting the remaining time on the NIBP automatic interval timer 322b from the original interval duration.
The pulse rate frame 314b contains a representation of the patient's pulse rate. The representation of the patient's pulse rate is based on one or more measurements of the patient's pulse rate. In different embodiments, the pulse rate frame 314b contains different representations of the patient's pulse rate. In the example of
The pulse rate alarm status area 324a specifies an upper alarm limit and a lower alarm limit. The upper alarm limit and the lower alarm limit define a pulse rate alarm range. An alarm associated with the patient's pulse rate is active when the patient's pulse rate is outside the pulse rate alarm range.
The SpO2 frame 314c contains a representation of the patient's SpO2 level. The representation of the patient's SpO2 level is based on one or more measurements of the patient's SpO2 level. In different embodiments, the SpO2 frame 314c contains different representations of the patient's SpO2 level. In the example of
The temperature frame 314d contains a representation of the patient's body temperature. The representation of the patient's body temperature is based on one or more measurements of the patient's body temperature. In different embodiments, the temperature frame 314d contains different representations of the patient's body temperature. In the example of
In some embodiments, the PMP device 200 can measure the patient's temperature in either a predictive mode or in a direct mode. When the PMP device 200 measures the patient's temperature in the predictive mode, the PMP device 200 predicts the patient's current temperature based on periodic readings of the patient's temperature. When the PMP device 200 measures the patient's temperature in the direct mode, the PMP device 200 continually measures the patient's temperature.
The temperature value in the temperature frame 314d is based on measurements received from a thermometer attached to a patient. When the PMP device 200 measures the patient's temperature in the predictive mode, the thermometer can be located at various places on the patient's body. Example locations on the patient's body where the thermometer can be located include in the patient's mouth, on the patient's thigh, in the patient's armpit, in the patient's rectum, and other locations.
The display screen 218 enables a user to select the parameter reporting frames 314a-314d in order to change how the physiological parameters are represented in the parameter reporting frames 314a-314d. In other words, each of the parameter reporting frames 314a-314d contains an initial representation of a physiological parameter. The parameter reporting frame displays an alternate representation of the physiological parameter instead of the initial representation of the physiological parameter when a user selects the parameter reporting frame. For example, selecting the temperature frame 314d toggles the temperature value between being expressed in Fahrenheit or Centigrade. This feature is referred to as “tap to toggle.” In another example, when a user selects the pulse rate frame 314b, the PMP device 200 displays a waveform in the pulse rate frame 314b instead of a number representing the patient's current pulse rate. The waveform represents a patient's pulse over time. In this example, when the user selects the pulse rate frame 314b again, the PMP device 200 displays a number in the pulse rate frame 314b representing the patient's current pulse rate. In yet another example, when the user selects the SpO2 frame 314c, the PMP device 200 displays a plethysmographic waveform view in the SpO2 frame 314c.
Furthermore, in the example of
For example,
When the PMP device 200 is configured with the oxygen saturation sensor module, non-invasive blood pressure module, respiration rate sensor module, pulse rate sensor module and end-tidal carbon dioxide sensor module and these modules are installed in the PMP device 200, space is allocated on the user interface of PMP device 200 to display physiological parameters from these modules. For example, areas are allocated on the user interface of PMP device 200 for the display of oxygen saturation, non-invasive blood pressure, respiration rate, pulse rate and end-tidal carbon dioxide. In a similar manner, when a physiological module is uninstalled at the PMP device 200, the PMP device 200 is reconfigured to remove or reassign an area of space previously allocated on the user interface of the PMP device 200 for the physiological module that is uninstalled.
In examples, the user interface for PMP device 200 displays the base configuration 402 regardless of whether sensor devices corresponding to the physiological modules are connected to a patient. For example, the user interface for PMP device 200 displays an area for ETCO2 when an ETCO2 module is installed in PMP device 200, regardless of whether an ETCO2 sensor is actually connected to the patient and obtaining physiological data from the patient.
When a configuration of PMP device 200 changes as a results of installing one or more additional HCE modules in PMP device 200 or as a result of activating one or more operational features of PMP device 200, the base configuration 402 changes. For example, when an integrated pulmonary index (IPI) is configured on for the PMP device 200, base configuration 402 changes to example configuration 404. In example configuration 404, a user interface display area is added for IPI and display areas SpO2 and Pulse become smaller. The IPI provides a measurement of a patient's pulmonary health or breathing, typically as a number from 1 to 10.
When a device for calculating noninvasive total hemoglobin (SpHb) is installed at PMP device 200, base configuration 402 changes to example configuration 408. When a thermometer module is installed in PMP device 200, base configuration 402 changes to example configuration 412.
In addition to HCE modules being installed and operational features being activated at base configuration 402, HCE modules may be installed and operational features may be activated for other configuration.
When a SpHb module is added to configuration 602, configuration 602 changes to example configuration 606. When IPI is configured on at PMP device 200 having a configuration 604, configuration 604 similarly changes to configuration 616.
For the examples shown in
In other examples, the user interface of PMP device 200 may be dynamically configured based on the detection of one or more physiological sensor devices or based on the activation of one or more operational features. For example, if a wireless thermometer device is detected at PMP device 200 having base configuration 402, in examples base configuration 402 changes to configuration 412.
For example, the PMP device 200 may be operating in a spot check workflow for a patient. In the spot check workflow, for example, clinicians may obtain vital signs for the patient, for example NIBP and temperature, on a non-continuous basis, for example one or more times during a nurse's shift.
If a clinician connects a continuous monitoring sensor device, for example an ETCO2 sensor device to the patient, the workflow for the patient becomes a continuous workflow. When the PMP device 200 is operating with the continuous workflow, the PMP device 200 obtains a series of measurements of one or more physiological parameters of a single monitored patient continuously over a period of time. The continuous measurements can be taken over short intervals, such as 1 millisecond, 0.5 second, 1 second, 2 seconds, etc.
In examples, a display screen 704 may be displayed on the PMP device 200 to alert the clinician that the PMP device 200 is changing to a continuous workflow. In example display screen 704, the clinician is alerted to the change in workflow by a dialog box 706 and asked to confirm or reject the change.
When the clinician approves the change to the continuous workflow, the PMP device 200 displays example display screen 708, asking the clinician to verify the identity of the patient. In example display screen 708, the clinician is asked to confirm or reject the change via dialog box 710.
When the clinician verifies the identity of the patient, example display screen 712 is displayed on the PMP device 200. The example display screen 712 shows that the workflow has been changed to continuous monitoring for the patient on PMP device 200. Other and different display screens may be displayed.
Example display screen 714 shows that the PMP device 200 is now in continuous monitoring mode. Physiological data being monitored in continuous monitoring include respiration rate (RR) 716 and end-tidal carbon dioxide (ETCO2) 718.
In examples, when a physiological sensor device for continuous monitoring is removed from a patient, the workflow for the patient may be automatically changed on PMP device 200 from continuous monitoring to spot check monitoring. Automatically changing a workflow from a spot workflow to a continuous workflow may be referred to as auto up-shift. Similarly, changing a workflow from a continuous workflow to a spot workflow may be referred to as auto down-shift.
The automatic shifting of the workflows based on the current status of the PMP device allows for greater usability. Such transitions allow the user to easily configure the device as desired to show the relevant physiological data that is being collected. In an alternative embodiment, the PMP device can be configured to automatically change workflow configurations (i.e., auto up-shift or down-shift) without prompting for confirmation from the user. In such a scenario, for example, the PMP device can automatically transition from a spot check workflow to a continuous workflow when a continuous sensor device is paired to the PMP device.
When an alarm occurs, an exception event is generated and a new column, for example column 806, is displayed corresponding to when the alarm occurred. For example, if the alarm occurred at 8:11, the new column, shown having column header 8:11+, is displayed between the 8:00 and 9:00.
When the column header of column 806 is selected, trend display 804 is displayed. Trend display 804 shows physiological data for the selected parameters at minute intervals instead of the hour intervals shown in trend display 802. In addition, as shown in
In examples, when a user wants to return to the normal display of one hour intervals, the user clicks an area of the header in trend display 804 and trend display 802 is displayed again. In examples, the time intervals or one hour for trend display 802 and 1 minute for trend display 804 can be adjusted to other time interval values.
A common way of incorrectly connecting the CO2 sensor is to fail to completely tighten a connection of the CO2 sensor to the PMP device 200. To mitigate against incorrectly tightening the connection of the CO2 sensor to the PMP device 200, the clinician is prompted each time the CO2 sensor is attached to the PMP device 200 to remind the clinician to connect the CO2 sensor correctly.
As shown, in
At operation 1004, the physiological parameter monitoring platform device is configured to allocate display areas for each of the identified HCE modules. The display areas provide for a display of physiological data obtained by the HCE modules. The display areas are located on a display screen of the physiological parameter monitoring platform device. The display areas are specific to the HCE modules configured, as shown in
At operation 1006, the physiological parameter monitoring platform device detects that one or more additional HCE modules are installed in the physiological parameter monitoring platform device. At operation 1008, the physiological parameter monitoring platform device is reconfigured to allocate display space for each of the additional HCE modules. In the process of allocating display space for each of the additional HCE modules, display space for previously identified HCE modules may be decreased in size, as shown in
At operation 1104, a second workflow physiological sensor device is attached to the patient. For example, a clinician may have attached a sensor device for measuring end-tidal carbon dioxide (ETCO2) to the patient. ETCO2 is typically measured continuously as part of a continuous workflow.
At operation 1106, a determination is made as to whether a second workflow physiological sensor device is attached to the patient. When it is determined at operation 1106 that the second workflow physiological sensor device is attached to the patient, at operation 1108, the clinician is prompted that that the workflow is being changed from the first workflow to the second workflow, for example from the spot check workflow to the continuous workflow. The clinician is also prompted to provide permission for permitting the workflow to be changed from the first workflow to the second workflow. Prompting is done to alert the clinician that the physiological parameter monitoring platform device is ready to change the workflow and to indicate to the clinician, in examples, that other changes may occur. For example, vital signs data obtained using the spot workflow and not yet sent to the EMR system may be deleted from the physiological parameter monitoring platform device.
At operation 1110, after the clinician gives permission for the change of workflow, the clinician is prompted to confirm the identity of the patient. In examples, a dialog box similar to dialog box 705, may be displayed showing identification information for the patient and asking the clinician to confirm.
At operation 1112, after the clinician confirms the identity of the patient, the physiological parameter monitoring platform device is reconfigured to the second workflow, for example PMP device 200 is reconfigured to the continuous workflow. At operation 1114, physiological data is obtained from the patient using the second workflow.
At operation 1202, physiological data for a patient is displayed at first time intervals on a display screen of the physiological parameter monitoring platform device. In examples, the physiological data is obtained at different times, typically at one hour intervals, and the display of the physiological data at each of these times provides a display of a trend in the physiological data over time.
At operation 1204, an alarm is received at the physiological parameter monitoring platform device. The alarm typically indicates that one or more physiological parameters being monitored for the patient have values outside an allowable range for these physiological parameters. For example, a physiological parameter by be lower than a lower threshold limit or higher than an upper threshold limit.
At operation 1206, a column of physiological data is displayed corresponding to a time at which the alarm occurred. For example, if the alarm occurred at 8:11, a column of physiological data at time 8:11 is displayed. The column of physiological data is placed between hourly columns of physiological data, for example between 8:00 and 9:00, as shown in
At operation 1208, the column of physiological data is selected, typically by clicking on a header of the column. For example, the column may be selected by clicking on the column header of column 806. As shown in
As a result of selecting the header of the column displaying the alarm data, at operation 1210, physiological data is displayed at shorter time intervals than previously displayed. For example, whereas at operation 1202, physiological data for the patient may be displayed at one hour intervals, at operation 1210, physiological data for the patient may be displayed at one minute time intervals.
In addition, as shown in column 808 of
At operation 1302, a respiration sensor device is attached to PMP device 200. At operation 1304, the PMP device 200 detects that the respiration sensor is attached to the PMP device 200. In examples, the respiration sensor device includes a hose and the PMP device 200 includes a hose sensor. When the respiration sensor device is attached to the PMP device 200, the hose sensor detects that that the respiration sensor device is attached to the PMP device 200. It examples, the respiration sensor device triggers the hose sensor when the respiration sensor device is attached to the PMP device 200.
At operation 1306, a warning message is displayed on the physiological parameter monitoring platform device. An example warning message, shown on example window 902, instructs the clinician to turn a connector completely to the right until tight. Other warning messages are possible.
