OPERATIONAL CHARACTERISTICS
I.
Functional and Operational Characteristics
The gas-powered GO
2
VENT™ provides constant flow, pressure cycled automatic
ventilatory support for both breathing and non-breathing patients. The primary
working mechanism of the GO
2
VENT™ (refer to Figure 1) is the [1] modulator
with [a] peak inspiratory pressure (PIP) and the [b] breathing rate adjustment
dials, which includes an exhalation valve that opens at one pressure (PIP) and
closes at another lower pressure (PEEP). The remaining components of the
GO
2
VENT™ consist of the [2] pressure manometer, [3] FiO
2
Control Knob, [4]
patient connection port, [5] redundant pressure pop-off valve, and [6] one-way
valve for entraining additional air.
The pulmonary modulator provides the actual ventilatory support. The primary
working mechanism of the pulmonary modulator is the diaphragm. The
diaphragm is spring loaded, designed like a pressure pop-off valve except the
spring force is adjustable (the [a] PIP Dial).
