"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.
