Brief summary

Prospective, randomized, blinded, cross-over study assessing the effectiveness of adaptive servo-ventilation (ASV) in treating patients who have obstructive sleep apnea (OSA) complicated by central sleep apnea (CSA) due to the chronic use of opioid medications

Detailed description

The trial seeks to determine the efficacy and patient comfort of ASV and bi-level positive airway pressure (PAP) modes for the treatment of obstructive sleep apnea (OSA), complicated by CSA secondary to opioid use. Subjects will be randomized to one of two groups, utilizing a cross-over design to evaluate the two modes with the subject as their own control. Subjects will be asked to undergo two PSG studies; one with ASV titration and one with bi-level treatment, using the current pressure prescription. The study comprises two visits. Subjects will be asked to complete patient satisfaction questionnaires following their PSG studies. It is anticipated that total subject participation will be no longer than one month.

Interventions

DEVICEAdaptive servo-ventilation (ASV)

Adaptive servo-ventilation (ASV) is a form of positive airway pressure (PAP) that is delivered based on the needs of the individual.

DEVICEBi-Level PAP

Bi-Level PAP delivers therapy at 2 pressures IPAP and EPAP that are fixed.

Design outcomes

MeasureTime frameDescription
Apnea Hypopnea Index (AHI)Up to 1 monthSubjects completed 2 overnight sleep studies (polysomnography (PSG)). The Apnea Hypopnea Index (AHI) metric is collected from the PSG study. Patients were equally distributed according to the therapy used first (ASV then Bi-Level or Bi-Level then ASV).

Secondary

MeasureTime frameDescription
Patient ComfortUp to 1 monthSubjects completed patient-satisfaction questionnaires after each polysomnography (PSG) study. Satisfaction with PAP: 0=Very Dissatisfied, 100=Very Satisfied
