II. Clinical Considerations
The GO
2
VENT™ provides short term, pressure cycled, and constant flow
ventilatory support for either breathing or non-breathing patients. This allows
the patient to receive consistent and reliable ventilatory support. Because the
GO
2
VENT™ is pressure cycled, changes in the patient’s lung compliance will
cause a change in the patient’s breathing rate. The GO
2
VENT™ is positional
sensitive. Final adjustments should be made with the GO
2
VENT™ in its
secured operating position. The GO
2
VENT™ is pressure cycled on inhalation
and exhalation (PIP and PEEP) which minimizes the possibility of gas trapping.
During inhalation, exhalation will not start until PIP is reached. During
exhalation, inhalation will not begin until pressure drops to PEEP. For the
spontaneously breathing patient, the rate dial of the GO
2
VENT™ is set so the
baseline pressure is above the intrinsic PEEP allowing the patient to initiate
inhalation by drawing the baseline pressure down to the set PEEP. Because the
GO
2
VENT™ is a constant flow pressure cycled device, changes in patient
compliance will result in changes in the respiratory rate (stiffer or smaller
compliances produce faster rates). The advantage of this minimizes the danger
of barotrauma. It should be emphasized that the GO
2
VENT™ is to be used only
by trained personnel who continuously monitor the patient. The GO
2
VENT™ is
not an ICU stand-alone ventilator with multiple monitoring features.
Setup and use of the GO
2
VENT™ is simple (refer to Setup Instructions in Section
III on page 7). Set desired flow (Q), adjust PIP pressure dial to obtain desired
inspiratory time (t
insp
) to attain tidal volume (TV = Q x t
insp
see Tidal Volume
Table 1). The gas flow, patient’s lung compliance, and PIP settings control the
inspiratory time and tidal volume. Then adjust rate dial to obtain desired
breathing rate.
