O2-MAX™ Disposable CPAP System is a variable flow venturi device that uses an oxygen supply in conjunction with entrained air to generate an output flow. O2-MAX™ uses a 50psi (~ 4 bar) oxygen supply, and can generate flows up to 140 lpm and fractional inspired oxygen (FiO2) from approximately 30% to 100%. The O2-CPAP valves which are snapped onto the anti-asphyxia housing end of the circuit, are used to maintain positive pressure flow rates from 60 to 140 lpm. For use in a wide range of respiratory distress conditions O2 delivery from 30% to 100% FiO2 and flow rates up to 140 l/m Easy to use 3-SET™ O2-CPAP™ valve with adjustable pressure settings of 5.0, 7.5 and 10.0cm H2O that does not require a manometer
