WebBecause the expiratory limb is occluded, gas that enters the test lung when the bag is squeezed will be trapped in the test lung. The maximum pressure will be determined by the compliance of the “test lung” (breathing bag) and the APL valve in the manual mode, or the pressure limit set on the ventilator while in the mechanical ventilation mode. WebSetup instructions for dual limb breathing circuit for adult and pediatric patients Installing the expiratory valve Refer to the figure below. 1. Remove the safety cover. 2. Ensure the membrane is properly aligned with the expiratory valve housing and the metal plate faces up (A). 3.
