Abstract

The present invention discloses a control algorithm of a CPAP system or providing air at positive pressure for respiratory therapy to a patient, the CPAP system comprising: a respiratory pressure therapy - RPT - device configured to supply a flow of air at a therapeutic pressure; a patient interface forming a plenum chamber pressurizable to the therapeutic pressure, the patient interface including a seal-forming structure constructed and arranged to form a seal with a region of a patient's face surrounding an entrance to a patient's airways; and an air delivery tube configured to pass the fl ow of air at the therapeutic pressure from the RPT device to the patient interface, the control algorithm comprising: measuring ambient humidity; setting a target gas temperature based on the measured ambient humidity and a preferred gas temperature setting from the patient; measuring the gas temperature at the patient interface; and controlling power to the controllable heater to correct any differences between the target gas temperature and the measured gas temperature.
