DELIVERING VARIABLE POSITIVE AIRWAY PRESSURE DEPENDING ON AWAKE STATE AND SLEEP DISORDERED BREATHING

摘要

Positive airway pressure (“PAP”) systems and methods are provided which supply a patient with a range of pressures for treatment when the patient is determined to be asleep, and an awake pressure for use when the patient is determined to be awake, the awake pressure configured for the comfort of the patient. The awake pressure is configured to be lower than the lower bound of the pressure range and can be a therapeutic or sub-therapeutic pressure. The PAP systems and methods disclosed herein advantageously allow for the pressure range to be tailored for effective treatment of sleep disordered breathing while allowing the awake pressure to be set for the comfort of the patient. This can advantageously increase both the efficacy of the treatment of SDB and patient compliance with the treatment.

1. A positive airway pressure system comprising:
a flow generator configured to provide gas at a pressure to a patient; a user interface configured to provide to the patient the gas at the pressure; a conduit that provides a path for the gas from the flow generator to the user interface; a sensor configured to measure breathing of the patient; and a control system configured to:
detect sleep disordered breathing based at least in part on analysis of data acquired by the sensor;determine a sleep state of the patient based at least in part on analysis of data acquired by the sensor;control the flow generator to provide a pressure between a low pressure and a high pressure when the sleep state is determined to be asleep, the pressure provided based at least in part on whether sleep disordered breathing is detected; andcontrol the flow generator to provide an awake pressure different from the low pressure if the sleep state is determined to be awake, the awake pressure is selected by a user.
