the following:
• Inspiratory (
B
) and expiratory (
C
) flow sensors (transducers)
• Patient airway (
D
) and manifold (
E
) pressures (transducers)
• Oxygen sensor (in breathing system)
• Inspiratory Flow Valve
• Gas Inlet Valve
• SCGO solenoid, SCGO/CGO position switches (if SCGO installed)
• Canister release switch
• ABS On switch
• ACGO position switch (if ACGO installed)
• O
2
Flush switch
• Bag/Vent switch
• Accessory Power (for task lights)
The Ventilator Interface board functions are managed locally by a microcontroller. The
microcontroller communicates data values to the controlling CPU via an RS-422 serial
interface.
