  • Page 22: Breathing System

    Theory of Operation Components 37. Bellows Assembly The AS3000 employs ascending ventilation bellows, in which mixed gas is stored. Drive gas supplied by the ventilator forces the bellows to descend sending mixed gas into the inspiratory passage of patient's airway. If a patient's airway suffers from gas leakage, the bellows will collapse, informing the operator of a possible problem.

  • Page 114: Calibration

    Calibration Introduction This section provides detailed information required to properly test and calibrate the AS3000. Calibration consists of making mechanical and electrical adjustments with the proper test equipment. The instrument should be tested and calibrated after repairs have been completed or at regular intervals as part of a periodic maintenance procedure. NOTE: Both calibration and a functional test must be performed to verify complete and proper operation.
