Measure
Unblinded Investigational Arm
Participants participated in an unblinded investigational phase of the trial prior to, and separate from, the single-blind cross-over phase of the trial. Data was collected from the his phase to aid the final development of the algorithm before proceeding to algorithm validation (ie. cross-over phase).
Standard AutoSet Algorithm
Participants first received therapy with the Standard AutoSet algorithm for one night, and then received therapy with the Modified AutoSet algorithm (an AutoSet device with an algorithm developed for sleep breathing parameters specific to females) the following night.
Modified AutoSet Then Standard AutoSet
Participants first received therapy with the Modified AutoSet algorithm (an AutoSet device with an algorithm developed for sleep breathing parameters specific to females) for one night, and then received therapy with the standard AutoSet algorithm the following night.

PRIMARY outcome

Timeframe: 1 day

Population: Reported results only include data from the blinded cross-over sequence arms (ie. Standard and Modified AutoSet algorithms). Data from the Unblinded Investigational phase of the trial was excluded as this phase was exploratory only to help refine the algorithm, and so, was not intended to be included in the final dataset.
