| 发明名称 | Pressure adjustment method for CPAP machine | ||
| 摘要 | A positive airway pressure apparatus is automatically adjusting. Pressure increases in response to apnea events when the apparatus is in one or more responsive states. Pressure does not increase in response to apnea events when the apparatus is in a non-responsive state. The apparatus switches between responsive and nonresponsive states depending upon any of a number of different criteria that help differentiate between open airway apnea events and closed airway apnea events. | ||

| 主权项 | 1. A method for controlling an automatically adjusting PAP apparatus, comprising: operating a controller in a first responsive state in which the controller is configured to respond to a first series of non-isolated apneas by increasing an output pressure of a gases flow source; entering a pause state when a total number of pressure increases in response to non-isolated apneas exceeds a threshold, the pause state having a predefined duration, wherein during the pause state, the controller increases the output pressure of the gases flow source in response to flow-limited breaths and non-flow limited hypopneas but does not increase the output pressure in response to apneas; and after the pause state, operating the controller in a second responsive state in which the controller is configured to respond to a second series of non-isolated apneas by increasing an output pressure of a gases flow source. | ||
