Abstract
Disclosed are systems and processes related to cardiopulmonary resuscitation (CPR). One embodiment of the system comprises an inspiration chamber and an expiration chamber, which work cooperatively to provide gas (e.g., Oxygen (O2)) to a subject (e.g., human patient) during inspiration and extract and expel expired gas (e.g., Carbon Dioxide (CO2)) from the subject during expiration as a medical professional applies CPR to the subject. In other words, this disclosure provides systems and processes that allow for substantially synchronous chest compressions with positive pressure active inspirations and, also, substantially synchronous chest decompressions with negative pressure active expirations.
Claims17
A system comprising:
- an inspiration chamber having an inspiration chamber top and an inspiration chamber bottom;
- an inspiration chamber inlet for receiving gas into the inspiration chamber;
- an inspiration chamber outlet for expelling the gas from the inspiration chamber;
- an expiration chamber having an expiration chamber top and an expiration chamber bottom, the expiration chamber top aligning substantially with the inspiration chamber top, the expiration chamber bottom aligning substantially with the inspiration chamber bottom;
- an expiration chamber inlet for receiving expired gas;
- an expiration chamber outlet for expelling the expired gas;
- a subject conduit for receiving the gas from the inspiration chamber and providing the gas to a subject, the subject conduit further for receiving the expired gas from the subject and providing the expired gas to the expiration chamber;
- a valve operatively coupled to the inspiration chamber outlet, the valve further being operatively coupled to the expiration chamber inlet, the valve for selectively opening the inspiration chamber outlet and closing the expiration chamber inlet when positive pressure from the inspiration chamber is applied to the valve, the valve further for selectively closing the inspiration chamber outlet and opening the expiration chamber inlet when no positive pressure is applied to the valve from the inspiration chamber.
