The present invention relates generally to a procedural sedation monitoring system, and a method for procedural sedation monitoring.
Even the most routine of medical procedures comes with an amount of risk. It is common for a local anesthetic to be utilized for many procedures, including minor surgery. For more serious and/or involved procedures, anesthesia is used to sedate the patient, which adds yet another risk factor to the overall procedure. Common forms of anesthesia include general anesthesia and procedural anesthesia, among others, and each comes with its own patient monitoring criteria in order to minimize the risk to the patient.
Procedural sedation is often touted as safe, but it is known to be a dangerous medical procedure. In fact, even in the hands of an experienced anesthesiologist, the American Society of Anesthesiologists (ASA) closed-claims database reveals that procedural sedation cases are potentially just a dangerous as general anesthesia cases. The highest risk category in these cases involves over-sedation and cardiorespiratory depression. The risk is most certainly higher in the hands of non-anesthesia sedation providers, as their level of expertise in recognizing the signs of over-sedation and/or cardiorespiratory depression is substantially lower.
Furthermore, it is also known that the majority of procedural sedation procedures are performed in an ambulatory surgery center (ASC), where regulatory compliance may be more lax than in a full hospital environment. Deep procedural sedation at an ASC has increased in incidence with consumer demand for patient comfort. In addition, the types and duration of procedures being performed with procedural sedation have increased as technology has improved capabilities. For example, ultrasound technology has improved and many conditions/diseases which formerly required surgery with general anesthesia can now be treated with less invasive tools, such that the procedure is performed while the patient is under procedural sedation. Some examples of such medical procedures performed with procedural sedation include endobronchial ultrasound (“EBUS”), transesophageal echocardiogram (“TEE”), gastrointestinal endoscopic ultrasound procedures, and interventional radiology procedures, just to name a few.
Currently, procedural sedation, such as may be employed during a routine colonoscopy, requires patient monitoring in accordance with the requirements defined by the ASA. More in particular, and as set forth by the ASA, a sedated patient must be constantly monitored during a medical procedure with at least the following: an electrocardiogram or ECG, a pulse oximeter, and a blood pressure monitor. Sensors capable of monitoring all three are typically wired to a monitoring device, which is usually a device having a screen showing visible signals and graphs and emitting an audible signal, typically, a beeping sound. These visual and audible indications are directed to a person standing or sitting close to the device.
It is understood, of course, that patient monitoring occurs and/or is required during other types of medical procedures as well including surgery without sedation; surgery performed with the patient under sedation ranging from light to moderate to deep sedation; total intravenous sedation; monitored anesthesia care, and/or general anesthesia, just to name a few.
However, as anyone with any experience in an operating theater or an ASC knows, medical personnel in a medical procedure room become so accustomed to the sights and sounds that they pay little to no attention to the display screen or the beeping sound, defined and recognized as alarm fatigue. Further, the aforementioned monitoring modalities, namely, an ECG, a pulse oximeter, and a blood pressure monitor which, once again, typically include a wired connection to the monitoring device, introduce a significant delay in indicating the actual real-time status of a patient's medical condition called physiologic signal latency and propagation delay, i.e., the length of time it takes for a signal to reach its destination. As just one example, it is believed that in some cases, a delay of as much as several minutes may exist between a patient's oxygen intake significantly decreasing, e.g., as may occur if the patient stops breathing, and the fact of this condition actually being reflected on the monitoring device screen and/or by the acoustic, i.e., beeping, feedback.
As a result of the foregoing, it is believed that many patient's consenting to procedural sedation for supposedly safe and often minimally invasive or even some non-invasive procedures are at considerable risk of permanent damage, and perhaps even death, as a result of partial respiratory or cardio failure which goes unnoticed by medical personnel during a supposedly safe and routine medical procedure, until it was too late.
Accordingly, there is an established need for a solution to one or more of the aforementioned problems.

Referring initially to
As may be seen from
In at least one embodiment, included among a plurality of patient sensors 111 of a patient monitoring assembly 110 in accordance with the present invention are an impedance cardiography sensor 115. An impedance cardiography sensor 115 in accordance with the present invention can detect minor changes in fluids and volumes in the thoracic cavity as result of cardiac hemodynamics, which also produce changes in the thoracic impedance thereby allowing estimation of parameters related to the mechanical function of the heart such as cardiac output, stroke volume, systolic time ratio, and the time of ejection of the left ventricle or the pre-ejection period. More importantly, an impedance cardiography sensor 115 may provide an indication of an impending disruption to a patient's normal heart function in advance of such an indication from an ECG sensor 112 and/or a blood pressure sensor 114, thus allowing a medical provider MP to take such corrective measures as may be needed sooner than later.
In at least one further embodiment, the plurality of patient sensors 111 of a patient monitoring assembly 110 comprises an acoustic respiration sensor 116, operatively positioned so as to measure the sound of air passing through a patient's glottis throughout a medical procedure. As will be appreciated, and similar to the measurements provided by an impedance cardiography sensor 115, an acoustic respiration sensor 116 may provide an indication of impending respiratory distress in the patient before such an indication is measured and transmitted by a pulse oximeter sensor 113. In some cases, this advance indication may be minutes ahead of a measurable decrease in a patient's blood oxygen level, minutes which in many cases may well prove to be life-saving as they will allow a medical provider MP to react sooner, and take necessary corrective measures to prevent respiratory failure and save a patient's life.
As before, a procedural sedation monitoring system 100 in accordance with at least one embodiment of the present invention further comprises a processor assembly 120. With reference once again to
Looking next to
A procedural sedation monitoring system 100 in accordance with at, least one embodiment of the present invention further comprises a processor assembly 120. As before, a processor assembly 120 comprises a patient monitoring signal receiver 122 configured and disposed to receive at least one patient monitoring signal 123 transmitted from at least one patient sensor 111 disposed in an operative engagement with a patient P undergoing a medical procedure. In at least one further embodiment, and as is shown best in
A patient signal processor 124 in at least one embodiment continuously receives and analyzes a plurality of patient monitoring signals 123 received from one or more patient sensors 111 disposed in an operative engagement with the patient P throughout a medical procedure, each indicative of at least one physiologic parameter of the patient P. More in particular, a patient signal processor 124 analyzes the plurality of patient monitoring signals 123 to determine if the data representative of one or more physiologic parameters of a patient P are within acceptable operative ranges for a patient under procedural sedation during a medical procedure.
In one embodiment, a processor assembly 120 further comprises an environmental control signal transmitter 126. In such an embodiment, a patient signal processor 124 analyzes a plurality of patient monitoring signals 123 and generates a corresponding plurality of environmental control signals 127 which are relayed to an environmental control signal transmitter 126 throughout a medical procedure in which a patient P is undergoing procedural sedation. Provided a patient monitoring signal 123 is indicative of a physiologic parameter within an acceptable operative range for a patient P under procedural sedation during a medical procedure, the patient signal processor 124 is programmed to generate a corresponding environmental control signal 127 indicative of a normal physiologic parameter of the patient P. However, in the event that a patient monitoring signal 123 is indicative of a physiologic parameter outside of an acceptable operative range for a patient P under procedural sedation during a medical procedure, the patient signal processor 124 is programmed to generate a corresponding environmental control signal 127 indicative of an abnormal physiologic parameter of the patient P. Furthermore, in the event the patient monitoring signal 123 is indicative of a physiologic parameter in a critical range, the patient signal processor 124 is programmed to generate a corresponding environmental control signal 127 indicative of an alarm condition for a physiologic parameter of the patient P.
In another embodiment, a processor assembly 120 further comprises a sensory feedback signal transmitter 128. In such an embodiment, a patient signal processor 124 analyzes a plurality of patient monitoring signals 123 and generates a corresponding plurality of sensory feedback signals 129 which are relayed to a sensory feedback signal transmitter 128 throughout a medical procedure in which a patient P is undergoing procedural sedation. Provided a patient monitoring signal 123 is indicative of a physiologic parameter within an acceptable operative range for a patient under procedural sedation during a medical procedure, the patient signal processor 124 is programmed to generate a corresponding sensory feedback signal 129 indicative of a normal physiologic parameter of the patient P. However, and similar to an embodiment comprising an environmental control signal transmitter 126, in the event that a patient monitoring signal 123 is indicative of a physiologic parameter outside of an acceptable operative range for a patient P under procedural sedation during a medical procedure, the patient signal processor 124 is programmed to generate a corresponding sensory feedback signal 129 indicative of an abnormal physiologic parameter of the patient P. Also similar to an embodiment comprising an environmental control signal transmitter 126, in the event the patient monitoring signal 123 is indicative of a physiologic parameter in a critical range, the patient signal processor 124 is programmed to generate a corresponding sensory feedback signal 129 indicative of an alarm condition for a physiologic parameter of the patient P.
A procedural sedation monitoring system 100 in accordance with at least one embodiment of the present invention comprises an environmental control assembly 130 disposed in communication with a processor assembly 120. More in particular, an environmental control assembly 130 comprises at least one environmental control device 131 disposed in a communicative arrangement with a controlled environment in which a medical procedure is performed on a patient P undergoing procedural sedation. Further, and as described above, a plurality of environmental control signals 127 are generated by a patient signal processor 124 and relayed to an environmental control signal transmitter 126, in the manner disclosed above, and transmitted by the environmental control signal transmitter 126 to at least one environmental control device 131, to control the operation of the at least one environmental control device 131 throughout the medical procedure.
As shown best in
An environmental control assembly 130 in accordance with at least one further embodiment of the present procedural sedation monitoring system 100 may comprise additional environmental control devices 131. In one embodiment, an environmental control device 131 comprises a light generator 134. Similar in operation to sound generator 132, a light generator 134 may generate and transmit an ambient lighting condition indicative of a measured physiologic parameter within an acceptable operative range for a patient P, as well as increasing or decreasing an ambient lighting condition in the event a measured physiologic parameter of the patient P falls outside of an acceptable operative range. Also similar to a sound generator 132, in the event one or more measured physiologic parameter is indicative of an alarm condition, a light generator 134 may generate and transmit a visible alarm signal such as sudden increase in intensity and/or flashing, so as to alert medical providers MP within the controlled environment of the alarm condition of the patient P. In similar fashion, an environmental control assembly may comprise a thermal control unit 136 operative to raise or lower a temperature in a controlled environment indicative of a measured physiologic parameter of the patient P undergoing a medical procedure therein.
In at least one embodiment, an environmental control assembly 130 further comprises a visual display generator 138. More in particular, in one embodiment a visual display generator 138 resembles the familiar, almost ubiquitous, patient monitor present in nearly every operating theater as well as in intensive care units wherein the physiologic parameters of the patient P are closely monitored by medical providers MP. As such, a visual display generator 138 includes a graphically and audible display of a plurality of measured physiologic parameters of a patient P such as respiration rate, temperature, blood pressure, pulse rate, oxygen levels, etc. In accordance with the present procedural sedation monitoring system 100, a visual display generator 138 graphically displays a plurality of measured physiologic parameters of a patient P on a plurality of visual displays strategically disposed throughout a controlled environment such that at least one of the plurality of visual displays is visible to each medical provider MP present in a controlled environment regardless of their proximity or orientation relative to the patient P.
While shown throughout the figures located in the same controlled environment in which a medical procedure is performed on a patient P undergoing procedural sedation, it is understood to be within the scope and intent of the present invention for a plurality of environmental control signals 127 generated by a patient signal processor 124 and relayed to an environmental control signal transmitter 126, in the manner disclosed above, to be transmitted by the environmental control signal transmitter 126 to at least one environmental control device 131 of an environmental control assembly 130 which is disposed and operable in a location remote of the controlled environment in which a medical procedure is performed on a patient P. As such, a medical provider in a location remote of the controlled environment in which a medical procedure is performed on a patient P can monitor the patient and/or the progress of the procedure. Alternatively, a medical provider may actually perform the medical procedure from a remote location, such as, by way of example, via robotic surgery. It is further understood that a plurality of environmental control signals 127 may be transmitted by the environmental control signal transmitter 126 to each of a plurality of environmental control devices 131 of each of a plurality of environmental control assemblies 130 each disposed and operable in a different remote location from the controlled environment in which a medical procedure is performed on a patient P.
A procedural sedation monitoring system 100 in accordance with at least one other embodiment of the present invention comprises a sensory feedback assembly 140 disposed in communication with a processor assembly 120. More in particular, a sensory feedback assembly 140 comprises at least one sensory feedback device 141 disposed in a communicative arrangement with a medical provider MP while a medical procedure is performed on a patient P undergoing procedural sedation. In one further embodiment, a plurality of sensory feedback signals 129 are generated by a patient signal processor 124 and relayed to a sensory feedback signal transmitter 128, in the manner disclosed above, and transmitted by the sensory feedback signal transmitter 128 to at least one sensory feedback device 141, to control the operation of the at least one sensory feedback device 141 throughout the medical procedure.
As shown best in
A sensory feedback device 141 in one embodiment includes a sensory feedback signal receiver 146 configured to receive a plurality of sensory feedback signals 129 which are relayed to a sensory feedback signal transmitter 128 by a patient signal processor 124, in the manner described above. Furthermore, a sensory feedback signal transmitter 128 transmits a plurality of sensory feedback signals 129 to a sensory feedback signal receiver 146 of a sensory feedback device 141, throughout a medical procedure in which a patient P is undergoing procedural sedation. A medical provider donning a sensory feedback device 141 may be located in the same controlled environment in which the patient P is undergoing a medical procedure, or the medical provider, or medical providers, may be located at one or more remote locations from where the medical procedure is being performed on the patient P. Once again, this permits one or more medical providers to monitor the patent and/or the progress of the procedure, as well as permitting one or more medical providers the ability to actually perform the medical procedure remotely, once again, such as via robotic surgery.
In at least one further embodiment, a sensory feedback device 141 comprises a sensory feedback generator 148 which is configured to generate a sensory feedback sensation 149 indicative of at least one physiologic parameter of a patient P undergoing a medical procedure. More in particular, when a measured physiologic parameter is within an acceptable operative range for a patient P under procedural sedation during a medical procedure, the patient signal processor 124 generates a sensory feedback signal 129 which is transmitted to a sensory feedback signal receiver 146 of a sensory feedback device 141, thereby causing a sensory feedback generator 148 to produce a sensory feedback sensation 149 which is sensed by the medical provider MP wearing the sensory feedback device 141 and is indicative of a physiologic parameter within an acceptable range. As one example, a sensory feedback sensation 149 may comprise a steady audible ambient sound, a steady ambient pulsation or vibration, and/or a steady warm or cool sensation, just to name a few, each indicative to the medical provider MP that one or more physiologic parameters of a patient P are within an acceptable range.
In the event a measured physiologic parameter is outside an acceptable operative range for a patient P under procedural sedation during a medical procedure, the patient signal processor 124 generates sensory feedback signal 129 which causes the sensory feedback generator 148 to produce a sensory feedback sensation 149 which is indicative of a physiologic parameter outside of an acceptable range. As just one example, an audible ambient sound may increase or decrease in volume, pitch and/or tone so as to indicate to the medical provider MP that a physiologic parameter either exceeds or is below an acceptable operative range, respectively. Alternatively, a steady ambient pulsation or vibration may increase or decrease in intensity and/or a steady warming or cooling sensation may become hotter or colder, once again, so as to indicate to the medical provider MP that a physiologic parameter has either exceeded or fallen below an acceptable operative range, respectively. Likewise, a different sound, pulsation or vibration or temperature sensation may be utilized to indicate to a medical provider MP that a high or low alarm condition has been measured for at least one physiologic parameter of the patient P by a patient monitoring assembly 110 during a medical procedure while the patient P is undergoing procedural sedation. As before, by alerting medical providers MP at the very onset of a deviation into a potential alarm condition, they are able to react quickly and take actions necessary to either avoid the alarm condition or to being actions needed to alleviate the alarm condition in the patient, either of which may prove to be life-saving measures.
With reference once again to
As will be appreciated from the foregoing, the combination of an environmental control assembly 130 and a sensory feedback assembly 140 in accordance with at least one embodiment of the present procedural sedation monitoring system 100 all but assures that one or more medical provider MP conducting a medical procedure on a patient P within a controlled environment will be informed of one or more measured physiologic parameters of the patient P throughout the medical procedure. More importantly, the medical providers MP will be informed of one or more measured physiologic parameters of the patient P with sufficient time to take corrective measures as may be needed in the event one or more physiologic parameters of the patient P fall outside of an acceptable operative range and/or are indicative of a life-threatening alarm condition in the patient P, thereby significantly decreasing the instances of irreparable harm and/or death of patients P during related to procedural sedation medical procedures.
As indicated above, the present invention is further directed to a method of procedural sedation monitoring.
To begin, a method of procedural sedation monitoring 200 in accordance with the present invention begins with measuring at least one patient physiologic parameter 202 throughout a medical procedure. In at least one embodiment, the present method 200 includes measuring a plurality of patient physiologic parameters 202 throughout the medical procedure. A method for procedural sedation monitoring 200 further comprises analyzing a plurality of patient physiologic data 206 which is generated by measuring a plurality of patient physiologic parameters 202.

In at least one embodiment, the present method further includes transmitting one or more environmental control device alarm signals 216 to one or more environmental control device alarms to effect operation of the same.

As in the case with generating an environmental control device alarm signal 214, if one or more of the plurality of patient's physiologic parameters are indicative of impending respiratory or cardiac failure or other measured critical physiologic parameter of the patient during procedural sedation, a sensory feedback alarm signal is generated, and the present method 200 further includes operating a sensory feedback device alarm 230 so as to alert medical providers of the patient's condition such that corrective actions may be implemented without delay. In at least one embodiment, the present method further includes transmitting one or more sensory feedback device alarm signals 228 to one or more sensory feedback device alarms to effect operation of the same.
