Manual Ventilation: General
During manual ventilation, the APL valve is set to the "MAN" position. The
patient system safety valve is activated. The piston of the ventilator is in the
upper end position in order to reduce the volume of the ventilator.
Manual Ventilation: Inspiration
During inspiration, expiratory valve remains closed. When the clinician com-
presses the breathing bag the gas mixture (expiratory gas and fresh gas)
flows through the fresh-gas decoupling valve, the inspiratory valve, the O2
sensor, the inspiratory hose, and the Y-piece into the patient's lung. The pres-
sure sensor measures the airway pressure. The APL valve limits the ventila-
tion pressure. Any excess amount of the gas mixture flows through the APL
valve and the non-return valve to the anesthetic gas scavenging system.
