The “Handheld” CAREvent® CPAP (Continuous Positive Airway Pressure) system provides superior CPAP delivery in a simple, compact device that can fit easily into your existing oxygen kit. The “ease of use” design concept and unique single use patient circuit with face mask, head harness and airway pressure gauge makes application and operation of the CAREvent® CPAP extremely simple for the rescuer and more comfortable and less distressing for the patient. CPAP has been proven to provide an effective method of treating respiratory distress from CHF, Asthma, COPD and pneumonia without having to intubate the patient. This is achieved by forcing fluid out of the alveolar space back into the interstitium, “splinting” open the alveoli, preventing alveolar collapse and allowing unimpeded alveolar ventilation. This provides more surface area for gas exchange, improving diffusion and oxygen uptake.
