A breathing circuit, shown in Figure 3–3, consists of:
• Circuit tubing to deliver air from the device to your interface (e.g., mask)
• A mask or other patient interface device to deliver the prescribed pressure to your nose or nose
and mouth, depending on which interface has been prescribed for you
• An exhalation device to vent exhaled air from the circuit
Circuit with Separate
Exhalation Device
NOTE:
Th e exhalation port may be part of the mask or may be part of a separate exhalation device, but
is required to minimize the potential for CO
Th e system senses your breathing eff ort and changes pressure levels when you inhale and exhale depending
on the mode of operation.
WARNING: Th e device can operate on AC or DC power. Th e DC power option is not intended as a
battery backup.
CAUTION: When DC power is obtained from a vehicle battery, the device should not be used while
the vehicle's engine is running.
