In FIG. 7, the DIY assisted respiration and/or ventilation system and method 600 operates in a similar manner as the method and system of FIG. 6, wherein a temperature sensor 702 can be employed to also include air temperature control for air and oxygen, and the like, entering the face mask 102. A direct current (DC) bi-directional blower 714 (e.g., bi-rotational pumps, Tesla turbines, bi-directional fan blade pumps, etc.) is provided to allow for programmable assisted respiration via the controller 624 configured for controlling a well-known programmable voltage inverter switch 706 that switches polarity of the voltage applied to a DC motor (not shown) of the blower 714 to provide for programmable assisted inhalation and exhalation through exhaust port 708, and the like.
Advantageously, the systems and methods of FIGS. 6-7 can be used provide a ventilator system that can meet minimum safe ventilator functionality based on clinical guidance, can reference hardware design for meeting minimum clinical requirements, can reference control strategies and electronics designs and supporting insights, can be used to provide results from testing in animal models, and like.
Advantageously, the systems and methods of FIGS. 6-7 can be used to satisfy clinical guidance, such as a minimum set of requirements for ventilation: Patients must be under the management of a trained clinician; the minimum controllable parameters in order to ventilate a patient include: BPM (breaths per minute): between 8-40 BPM; Tidal Volume (TV) (air volume pushed into lung): between 200-800 mL based on patient weight; I/E Ratio (inspiratory/expiration time ratio): recommended to start around 1:2; best if adjustable between range of 1:1-1:4; Assist Detection pressure. When a patient tries to inspire, they can cause a dip on the order of 1-5 cm H2O, with respect to PEEP pressure (not necessarily=atmospheric); airway pressure must be monitored; maximum pressure should be limited to 40 cm H2O at any time; Plateau pressure should be limited to max 30 cm H2O; the use of a passive mechanical blow-off valve fixed at 40 cm H2O is strongly recommended; clinician require readings of plateau pressure and PEEP (refer to clinical documentation tab); PEEP of 5-15 cm H2O required; many patients need 10-15 cmH2O; Failure conditions must permit conversion to manual clinician override, i.e. if automatic ventilation fails, the conversion to immediate ventilation must be immediate; Ventilation on room air is better than no ventilation at all. Blending of oxygen and air gas mixture to adjust FiO2 is not important in an emergency scenario. It is certainly nice to have that ability and can easily be implemented with a oxygen/air gas blender that some hospitals already have; covid-19 can get aerosolized (airborne), so HEPA filtration on the patient's exhalation is required or between the ventilator unit and the patient (at the end of the endotracheal tube) to protect clinical staff from certain infection; in-line HEPA filters can usually be purchased alongside manual resuscitator bags; heat and moisture exchanger should be used in line with the breathing circuit; failure conditions must result in an alarm, and like.
Advantageously, many of the components employed in the systems and methods of FIGS. 1-8 can be off-the-shelf components, and can be 3D printed, and the like, and employed during emergency situations, such as the 2020 covid19 worldwide pandemic, and the like, as will be appreciated by those of ordinary skill in the relevant art(s), based on the teaching of the present disclosure.
FIG. 8 is a diagram for a backpack version of the DIY respiration system and method employing off the shelf full face scuba masks, and USB powered air pumps, and blowers, and the like, and that can be employed with the systems and methods of FIGS. 1-7. In FIG. 8, a backpack 804 houses the power supply 118 (e.g., portable power supply, batteries, etc.) and blower 114 for delivering HEPA filtered air via the air tube 106 to the face mask 102 on the user 802. Advantageously, the configuration of FIG. 8 can be employed by first responders, and the like, at remote locations, and the like.
