ABSTRACT:
A method and a CPAP apparatus for characterizing mask systems provided. The CPAP apparatus can be calibrated by including sensors configured to measure flow and pressure. When the flow generator is fitted to a new or changed mask system, a method for calibrating the flow generator for the new or changed mask system. The method includes determining air flow characteristics using flow measurements made during a first test period when the flow through the mask system is open, measuring or estimating pressure in the mask system during a second test period when the flow through the mask system is blocked and determining air flow characteristics of the diffuser of the mask system using the air flow characteristics of the air delivery hose determined during the first test period and the pressure measurements made during the second test period.
