AUTOMATIC PRESSURE TITRATION

摘要

A pressure support methodology and system that utilizes at least two, and possibly all three, of information relating to (i) airway patency, i.e., the degree to which the patient's airway is open, (ii) the primary cause of the current sleep disordered breathing event, and (iii) the patient's response to previous pressure changes to automatically titrate pressure when presented with a sleep disordered breathing event. In another embodiment, pressure may be automatically titrated based solely on the primary cause of the sleep disordered breathing event.

主权项

1. A method of providing pressure support to a patient, comprising:
detecting an occurrence of a sleep disordered breathing event in the patient; and in response to the detecting, titrating a pressure of a flow of gas provided to the patient based on at least two of: (i) a determined patency of an airway of the patient, (ii) a determined cause of the sleep disordered breathing event, and (iii) a determined responsiveness of the patient to previous pressure changes in the flow of gas provided to the patient.
