Components Theory of Operation<br />
26. Vaporizer Storage Mount<br />
The Vaporizer Storage Mount provides the AS3000 with auxiliary placement for a<br />
vaporizer.<br />
27. Mains Supply Assembly<br />
The Mains Supply Assembly attaches the AS3000 to an external AC wall outlet. It also<br />
supplies power throughout the unit.<br />
28. Electronic Flowmeter Assembly<br />
The Electronic Flowmeter Assembly provides fresh gas flow measurement for the AS3000.<br />
29. Gas Box Assembly<br />
The Gas Box Assembly provides drive gas to the Breathing System and includes a safety<br />
valve to insure that pressure stays below 85 cmH2O. It also contains the PEEP valve, and the<br />
differential pressure sensors.<br />
30. YOKE Assembly<br />
The YOKE Assembly provides connection for three backup gas cylinders. The pressure<br />
regulator for the backup gas cylinder reduces the pressure of a high pressure gas cylinder<br />
down to 43.5 psi (300 kPa).<br />
31. AMP Cables<br />
The AMP Cables provide signal transmission between the electric box and gas circuit box.<br />
32. Electric Box Assembly<br />
The Electric Box Assembly provides, and distributes power to the AS3000.<br />
33. Rear Panel Assembly<br />
The Rear Panel Assembly protects, and provides heat dissipation for the electric box and<br />
auxiliary support for the backup gas cylinder.<br />
1.3.4 Other components (not identified in graphics)<br />
34. Inspiratory and Expiratory Valves<br />
The Inspiratory and Expiratory Valves are unidirectional valves that allow air to flow in only<br />
one direction.<br />
35. Absorber Canister<br />
The AS3000 uses two Absorber Canisters which can contain 1500 mL of soda lime each.<br />
They can be used for 6 - 8 hours each if full. Water generated from the reaction with CO2 is<br />
drained from a valve on the lower side of the canister.<br />
36. APL (Airway Pressure Limiting) Valve<br />
The APL Valve is used for limiting maximum airway pressure during manual ventilation. The<br />
adjustable range of the APL is 0 - 70 cmH2O. 1 - 8 0070-10-0683 AS3000 Service Manual
