WebAn incompetent inspiratory valve will allow exhaled CO 2 - containing gas to enter the inspiratory limb of the circuit during expiration (see animation below). During the next … 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.

Web1 If either of unidirectional valves becomes incompetent, exhaled gas enters inspiratory limb. During the next inspiratory cycle, inspired gas will have a higher concentration of CO 2, hence producing a higher baseline inspiratory CO 2 2 Rebreathing CO 2 also occurs when CO 2 absorbent is depleted.
