  • Page 126: Ventilator Theory

    Aespire View Ventilator theory The ventilator pneumatics are located in the rear of the breathing system. A precision flow valve controls gas flow to the patient. During inspiration, this gas flow closes the exhalation valve and pushes the bellows down. During expiration, a small flow pressurizes the exhalation diaphragm to supply PEEP pressure.

  • Page 127: O2 Monitoring Theory Of Operation

    10 Specifications and Theory of Operation O2 monitoring theory O2 monitoring measures O2 concentration in the patient circuit. The of operation O2 concentration measured from the O2 cell is shown on the ventilator display. The O2 sensor is an electrochemical device (galvanic cell). Oxygen diffuses through a membrane into the cell and oxidizes a base metal electrode.
