II. Clinical Considerations (continued)
Although peak pressures are listed on the side of the pressure dial, they are only
approximate. Clinicians using the GO
clinical judgment and monitor the patient appropriately. A manometer may be
connected between the modulator and the patient connector tee.
The GO VENT™ is pressure cycled on PEEP as well as PIP. In the pressure control
2
mode, there is no prolonged stage where the flow of exhalation gas stops for a
significant duration of time (in the pressure support mode, exhalation time is
determined by the patient). This occurs because the exhalation time is set with
the rate dial by varying the exhalation resistance so the patient just finishes
exhalation with the beginning of the subsequent inhalation. The volume of gas
with which the patient's lungs are inflated when reaching PEEP is the same as
with any other means of obtaining PEEP. As with all ventilatory support modes,
short exhalation times on patients with high airway resistance may lead to gas
trapping which is not detectable in the patient's external airways. Upon occlusion
of the patient's airways, the GO
rapidly.
The GO VENT™ will work with any mask that provides a good seal with the
2
patient. All clinicians should receive adequate training on the GO
mask prior to use. In the presence of a small leak, the GO
between PIP and PEEP. Noticeable changes in the presence of a leak are
increased inspiratory times and decreased expiratory times. The GO
works very well with an endotracheal tube.
Inhalation may be initiated by briefly removing the mask from the patient or
briefly disconnecting the modulator from the patient adapter tee. In either
event, inhalation begins because pressure has dropped down to PEEP and the
GO VENT™ is pressure cycled.

Upon contamination of the GO
disconnecting the modulator from the patient connector tee (see enclosed
instructions) and tapping out vomitus on a hard surface. Additionally, if needed,
the rate dial may also be removed to facilitate removal of vomitus from
modulator. This operation should take less than 20 seconds, and in a lab setting
has consistently been shown to take approximately 11 seconds. Alternatively,
upon contamination with vomitus, the clinician may choose to discard the device
and use a new one.
Inhalation and exhalation are audibly detectable and easily recognizable during
operation of the GO
