WebIncompetent inspiratory or expiratory valves will reduce the efficiency of gas circulation and result in rebreathing and consequent carbon dioxide retention. Some machines are equipped with valves made of deformable rubber: As the rubber ages, these discs tend to harden in a semi-open position, again allowing the valve to become incompetent. WebJul 1, 2005 · The MPDM detected the valve leak (Draeger 0.6 L/min flow leak; Ohmeda 0.9 L/min flow leak) when the incompetent valve discs were intentionally introduced into each type of machine.
