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, 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.
