18.3.1. OPERATION IN EXTREME HIGH / LOW TEMPERATURES
During high temperature operation, the ventilator may prompt an alarm
regarding its high temperature charge limit. The battery protection
circuit will stop charging below 0°C and over 50°C, as measured inside
the battery pack.
Normal ventilator operation may create heat in the battery compart-
ment. When operating in a hot environment you should remove the ven-
tilator padded case, increasing heat dissipation into the environment.
During low temperature operation, it is recommended to use the venti-
lator padded case. This will insulate the unit from the outside temper-
ature and retain the internal heat created by the blower motor and other
electrical heat-generating components.
18.3.2. OPERATION IN HIGH OR LOW ALTITUDE
The Ventway Sparrow is designed to operate at an altitude of -370 to
7620 meters (-1,200 to 25,000 feet). An internal altimeter measures the
ambient pressure, allowing the ventilator to compensate the flow
calculations for the changes in density and pressure.
If the operation altitude is outside of the specified values, a low priority
alarm will be activated. In this case the user should monitor the Peak
Inspiratory Pressure (PIP) and adjust the tidal volume so the same PIP is
achieved. It is also advised to monitor the breathing sounds and chest
excursion to assure the unit maintains adequate ventilation.
