In case of mechanical ventilation, during inspiration, gas flows through manual/auto switch 41, 
BYPASS valve 35 or sodalime canister 34, inspiratory valve 33, O2 sensor 39, airway pressure 
gauge 47, and inspiratory flow sensor 37 to the patient. During expiration, gas flows through 
expiratory flow sensor 38, expiratory valve 36 and manual/auto switch 41 to the folding bag or 
manual bag. Airway pressure is monitored by pressure sensor 53. 
 
The water generated by condensation is collected in the water collection cup on the bottom of 
breathing system. 
 
The breathing system is easily disassembled and is autoclavable at 134℃.
