摘要：
A method and apparatus are disclosed for determining airflow through a PAP device while applying PAP therapy. The actual speed of a blower 6 is measured. The desired motor current IDES required for the actual speed to approach or maintain a desired speed is used, together with the actual speed RPM ACT, in a flow estimation algorithm to determine flow through the PAP device. The estimation algorithm consists of a two-dimensional look-up table, where the inputs are the desired motor current and actual motor speed, and the output is the flow through the PAP device.
