In the absence of any measured flow disturbance, the pressure is allowed to decay slowly and hopefully an equilibrium pressure will be achieved that allows the patient to sleep arousal-free. AHI is calculated by dividing the number of events by the number of hours of sleep to determine whether a patient will require CPAP therapy. [new] Improve Somnopose import options.
