mask systems may not be compatible.
The mask should be worn only when the machine is turned on and operating
properly. Explanation: exhaled air is flushed out of the vents when the
machine is operating. If the unit is not operating, exhaled air will be
rebreathed. The vent holes on the mask should never be blocked.
At low pressures, the flow through the exhalation ports may be inadequate to
clear all exhaled gases. Some rebreathing may occur.
The airflow for breathing may be as much as 6°C (11°F) higher than room
temperature. Caution should be exercised if the room temperature is higher
than 35°C (95°F).
Do not drop or insert any objects into the air tubing or air outlet.
Do not open the flow generator case or attempt to adjust the unit.
If oxygen is used with this device, the oxygen flow must be turned off when
the device is not operating. Explanation: When the device is not in operation
and the oxygen flow is left on, oxygen delivered into the ventilator tubing may
accumulate within the device enclosure and create a risk of fire.
Always turn the flow generator on before the oxygen.
Always turn the oxygen off before the flow generator.
Oxygen supports combustion. Oxygen should not be used while smoking or in
the presence of an open flame.
