METHODS AND APPARATUS FOR CONTROLLING RESPIRATORY THERAPY WITH SUPPLEMENTARY OXYGEN

Apparatus and methods provide operations for a respiratory disorder therapy by generating a flow or pressure therapy with supplementary oxygen. The method may be implemented by one or more processors that may set one or more therapy parameters associated with generating a flow of air to a patient interface via an air circuit. The one or more processors may set one or more supplementary oxygen parameters associated with introducing supplementary oxygen into the flow of air at the air circuit. The method may involve computing an oxygen performance metric associated with characteristic(s) of a patient and the air flow with the supplementary oxygen. The computing may include applying function(s) comprising the therapy parameter(s) and supplementary oxygen parameter(s). Output, such as a display indicator or automated therapy control change(s), may be generated using the computed oxygen performance metric. Changes to therapy parameter(s) may be made to optimise the metric.
