WebIt is possible to place such a valve between the breathing system and the ventilator. In that case PEEP should be observed on the breathing system pressure gauge. The valve must still be placed in the correct orientation. If it is placed in the wrong direction, PEEP will not be delivered, but again, there will not be a circuit obstruction. 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.
