1 General information
• The device acts as an electronically controlled pneumatic
ventilation system. Power comes from an AC source with
internal battery backup. There is an optional extended bat-
tery backup available to order which protects against power
failure or unstable power and aids in intra-hospital trans-
port.
• The device’s pneumatic system delivers gas, while its electri-
cal systems control the pneumatics, monitor alarms, and
distribute power.
• When you input instructions or settings you use the device’s
microprocessor system accessing features by way of a touch
screen, push button keys, and a press-and-turn knob. Your
inputs become instructions for the device’s pneumatics to
deliver precisely controlled gas mixtures to a patient. The
device receives inputs originating from several sources such
as sensors within the ventilator. As the device receives this
monitored data, it adjusts gas delivery to the patient. The
graphic user interface (GUI) displays this data via the touch
screen display using various windows.
• The device’s microprocessor system controls gas delivery
and monitors the patient. The gas delivery and monitoring
functions are cross-checked by an alarm controller. This
cross-check feature helps prevent simultaneous failure of
these two main functions and minimizes the possible
hazards of software failure.
1.2.2 Gas supply and delivery
The device uses high-pressure oxygen, air and heliox from wall
supplies, cylinders, or the VENTILAIR II medical air compressor
(Figure 1-4). These gases enter though water traps with inte-
grated high-efficiency particle filters at the gas inlets.
