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.
