A system includes a respiratory device, a mask, a sensor, and a control system. The respiratory device is configured to supply pressurized air. The mask is coupled to the respiratory device and configured to engage a user during a sleep session to aid in directing the supplied pressurized air to the user. The sensor is configured to generate physiological data associated with the user. The control system is configured to analyze the physiological data to determine a first sleep stage of the user, and based on the determined first sleep stage of the user, (i) set a range of pressures for the respiratory device to supply the pressurized air, and (ii) set a rate of change of the pressurized air for the respiratory device to use when changing the supplied pressurized air from a first pressure within the range of pressures to a second pressure within the range of pressures. |
