Pressure controls are coupled so that the unit will not deliver a higher EPAP than
IPAP level when the unit is operated in the S, S/T, or T modes.
Pressure Calibration Accuracy: ± 2 cm H

Note: For specifications, all pressure measurements were made at the blower outlet unless
stated otherwise.
*Measured at the end of a 6-foot section of smooth inner lumen tubing.
