26. Vaporizer Storage Mount
The Vaporizer Storage Mount provides the AS3000 with auxiliary placement for a
vaporizer.
27. Mains Supply Assembly
The Mains Supply Assembly attaches the AS3000 to an external AC wall outlet. It also
supplies power throughout the unit.
28. Electronic Flowmeter Assembly
The Electronic Flowmeter Assembly provides fresh gas flow measurement for the AS3000 .
29. Gas Box Assembly
The Gas Box Assembly provides drive gas to the Breathing System and includes a safety
valve to insure that pressure stays below 85 cmH
2
O. It also contains the PEEP valve, and the
differential pressure sensors.
30. YOKE Assembly
The YOKE Assembly provides connection for three backup gas cylinders. The pressure
regulator for the backup gas cylinder reduces the pressure of a high pressure gas cylinder
down to 43.5 psi (300 kPa).
31. AMP Cables
The AMP Cables provide signal transmission between the electric box and gas circuit box.
32. Electric Box Assembly
The Electric Box Assembly provides, and distributes power to the AS3000.
33. Rear Panel Assembly
The Rear Panel Assembly protects, and provides heat dissipation for the electric box and
auxiliary support for the backup gas cylinder.

34. Inspiratory and Expiratory Valves
The Inspiratory and Expiratory Valves are unidirectional valves that allow air to flow in only
one direction.
35. Absorber Canister
The AS3000 uses two Absorber Canisters which can contain 1500 mL of soda lime each.
They can be used for 6 - 8 hours each if full. Water generated from the reaction with CO
2
is
drained from a valve on the lower side of the canister.
36. APL (Airway Pressure Limiting) Valve
The APL Valve is used for limiting maximum airway pressure during manual ventilation. The
adjustable range of the APL is 0 - 70 cmH
