Tube Temperature
If the air in the mask feels too warm or too cold, the patient can adjust the temperature to find what
is most comfortable or turn it off completely. The Tube Temperature can be set to anywhere
between 60–86°F (16–30°C).
The temperature sensor located at the mask end of the ClimateLineAir heated air tubing enables the
system to automatically control the temperature of the air delivered to the patient. This ensures the
temperature of the air delivered to the patient does not fall below the set minimum temperature,
therefore maximizing breathing comfort for the patient.
Humidity Level
The humidifier moistens the air and is designed to make therapy more comfortable. If the patient is
getting a dry nose or mouth, turn up the humidity. If the patient is getting moisture in their mask,
turn down the humidity.
The Humidity Level can be set to Off or between 1 and 8, where 1 is the lowest humidity setting
and 8 is the highest humidity setting.
For each humidifier setting, the Climate Control system delivers a constant amount of water vapor,
or absolute humidity (AH), to the patient's upper airway.
Automatic adjustment
The humidifier and ClimateLineAir heated air tubing are controlled by the Climate Control algorithm
to deliver constant humidity and temperature outputs. The system adjusts automatically to changes
in:
• ambient room temperature and humidity values
• flow due to pressure changes
• flow due to mask or mouth leak.
