There is an interesting new disposable CPAP type device. It is called the Rescuer from BLS Systems. It offers a combination of features we have not seen before. It is completely disposable and easy to use. Oxygen is supplied by a standard oxygen flowmeter.
The Rescuer has a tubular oxygen reservoir with an anti-asphyxiation valve. This enables it to deliver acceptable FIO2 at relatively low flow rates. The Rescuer can produce 15cm of CPAP pressure at 10LPM flow. The only other disposable device with a reservoir is the Smith Oxy-PEEP.
It also has both inhalation and more importantly, an exhalation filter. This reduces the risk of transmitting airborne pathogens in a confined-space EMS environment. The adjustable PEEP valve is convenient and quickly adjusted to meet patient requirements.
Last, it has a medication port built in. The swivel allows for some patient movement and the mask and strap system are available in two different configurations. Based on my discussions it may also be one of the least expensive of the disposable CPAP type devices.
