Beschreibung
Zusammenfassung:	A breathing assistance device with improved pressure characteristics provides a high level of CPAP per unit of supplementary respirable gas consumed while maintaining low CPAP fluctuations throughout the breath cycle utilizing a frustrum-shaped air channel that has no unblocked openings to accelerate air flow. In some embodiments, a manometer is provided for monitoring pressure and/or a pressure relief valve is provided as a safety measure against overpressure delivered to a patient. In some embodiments, the device is disposable for one-time or single patient use.
