‡
Compare the mask to the device. See your device manual if the values do not match.
‡
System One is not compatible with masks that use a separate exhalation device.
Specifications
Warning: The technical specifications of the mask are provided for your
healthcare professional to determine if it is compatible with your CPAP or
bi-level therapy device. If used outside these specifications, or if used with
incompatible devices, the mask may be uncomfortable, the seal of the mask
may not be effective, optimum therapy may not be achieved, disconnect alarms
may not be detected, and leak, or variation in the rate of leak, may affect device
function. The pressure flow curve shown below is an approximation of
expected performance. Exact measurements may vary.
