Abstract
A method is disclosed for operating a device that treats sleep disordered breathing (SDB) during successive treatment sessions, where the device provides continuous positive airway pressure during sleep. The method may include the steps of applying a constant treatment pressure during a first session, detecting SDB event(s) during the first treatment session and, in response to the detected event(s), adjusting the constant treatment pressure. During a setting procedure, a second constant treatment pressure is determined for a second treatment session which is subsequent to the first treatment session. The second constant treatment pressure is determined based on checking of a clock and the detected SDB event(S).
Claims30
An apparatus for providing positive airway pressure, comprising:
- a blower configured to provide pressurized air to a patient interface;
- a controller configured to:
- control an air pressure provided by the blower at a first therapeutic pressure treatment level during a first treatment session;
- detect the occurrence of sleep disordered breathing (SDB) events during the first treatment session;
- and
- adjust the first therapeutic pressure treatment level in response to the detected SDB events during the first treatment session;
- in a setting procedure, determine a second generally constant therapeutic pressure treatment level to be provided in a second treatment session, the second treatment session being subsequent to the first treatment session, the second generally constant therapeutic pressure treatment level being determined based on checking of a clock and the sleep disordered breathing (SDB) events detected from the first treatment session;
- and
- maintain the air pressure at the second generally constant therapeutic pressure treatment level without changing the therapeutic pressure treatment level during the second treatment session,
- wherein the first treatment session comprises at least one sleep session and the second treatment session comprises a different sleep session.
A method for controlling an apparatus that provides positive airway pressure, comprising:
- controlling with a processor setting of a blower for an air pressure provided at a first therapeutic pressure treatment level during a first treatment session, the blower configured to provide pressurized air to a patient interface;
- detecting with the processor the occurrence of sleep disordered breathing (SDB) events during the first treatment session;
- and
- adjusting with the processor the first therapeutic pressure treatment level in response to the detected SDB events during the first treatment session;
- in a setting procedure, determining with the processor a second generally constant therapeutic pressure treatment level to be provided in a second treatment session, the second treatment session being subsequent to the first treatment session, the second generally constant therapeutic pressure treatment level being determined based on checking of a clock and the sleep disordered breathing (SDB) events detected from the first treatment session;
- and
- maintaining with the processor control of the air pressure of the blower at the second generally constant therapeutic pressure treatment level without changing the therapeutic pressure treatment level during the second treatment session,
- wherein the first treatment session comprises at least one sleep session and the second treatment session comprises a different sleep session.
