Rebreathers have been used in the medical world for many years in anesthesia. More recently, rebreathers have been used as oxygen delivery devices for emergency treatment in systems such as the D.A.N. REMO2. The REMO2 is used primarily for treating decompression sickness on dive boats, and during patient transportation to emergency facilities.

A rebreather can dramatically extend the life of any oxygen supply, or make the gas cylinder small enough to be extremely portable. Potential applications for rebreathers are in ambulances, police cars, and other emergency vehicles where multiple patients could be treated more efficiently with small, lightweight rebreathers.
ExtendAir CO2 absorbent cartridges used in medical rebreathers can have a 100% increase in minimum duration when compared with granular canisters.  So, there is the potential to double the duration of an existing system or, you can build a smaller canister with the same duration. In either case, all of the other advantages such as ease of use and no powdering still apply.

Extendair cartridges for medical devices can be supplied in disposable canisters with breathing hose connections on one end of the housing. Please contact Micropore if you would like a quote on a canister for a medical device application.
