Abstract:
1. A method of providing pressure support to a patient, comprising: monitoring whether the patient is responsive or non-responsive to previous pressure increases in a flow of gas provided to the patient, wherein the patient is responsive to previous pressure increases if the previous pressure increases have resolved previous sleep disordered breathing events of the patient and the patient is non-responsive to previous pressure increases if the previous pressure increases have not resolved the previous sleep disordered breathing events of the patient; detecting an occurrence of a current sleep disordered breathing event in the patient; and in response to the detecting, performing one or both of: (i) determining whether an airway of the patient is open or closed, and (ii) determining whether the sleep disordered breathing event is centrally mediated; in response to determining: (a) that the airway of the patient is closed, (b) that the sleep disordered breathing event is centrally mediated, or (c) both (a) and (b), determining whether the patient is responsive or non-responsive to previous pressure increases; in response to determining that the patient is responsive to previous pressure increases, increasing the pressure of the flow of gas provided to the patient; and in response to determining that the patient in non-responsive to previous pressure increases, decreasing the pressure of the flow of gas provided to the patient or not changing the pressure of the flow of gas provided to the patient.
