Comparison Study Using APAP With and Without SensAwake in Patients With OSA and PTSD

Fisher and Paykel Healthcare85 enrolled

Overview

The purpose of this research is to examine the application of AutoCPAP with and without SensAwake in subjects with OSA and Post-Traumatic Stress Disorder (PTSD), and evaluate whether patients achieve better sleep quality and compliance with SensAwake, compared to the same treatment without SensAwake.

Conceptually, awareness of pressure occurs only during wakefulness. Thus reducing the pressure during wakefulness may improve therapy comfort and potentially adherence without compromising therapy efficacy. SensAwake™ is a unique pressure relief technology developed by Fisher \& Paykel Healthcare which detects irregularity in the flow signal indicative of the transition from sleep to wake. When the transition from sleep to wake is detected the device promptly reduces the pressure to help facilitate a return to sleep. It is hypothesised that AutoCPAP with SensAwake will improve patient comfort and compliance in the PTSD and OSA patients who are naïve to CPAP therapy. The investigators will not be blinded to the study. The participants will be blinded to the study.

Outcomes

Primary Outcomes

Adherence (Hours on Therapy)

Hours per night averaged over total time period measured.

Time frame: 4 weeks

Secondary Outcomes

Sleep Quality (Epworth Sleepiness Scale (ESS)

The ESS is a validated questionnaire that assesses an idnviduals likelihood of falling asleep in a variety of given situations (such as having a conversation with someone or stopped a red light while driving.) Each question is given a rating between 0 and 3, with 0 being no chance of falling asleep and 3 being high chance of falling asleep. Answers are then summed together to determine the level of sleepiness an individual is experiencing with a maximum score of 24. The higher the score, the more sleepy the person is. From a clinical perspective an ESS score of 0-10 indicates a normal level sleepiness, a score of 11-14 indicates mild sleepiness, a score of 15-17 indicates moderate sleepiness and a score of 18+ indicates severe sleepiness. Results below are reported as a mean change from baseline in which negative scores indicate reduction in ESS from baseline (less sleepiness). Positive scores indicate increase in ESS from baseline (more sleepiness.)

Time frame: Change from Baseline after 4 weeks

Insomnia Severity Index (ISI)

ISI; 0-7 = No clinically significant insomnia, 8-14 = Sub threshold insomnia, 15-21 = Clinical insomnia (moderate severity), 22-28 = Clinical insomnia (severe). Results reported in mean change from baseline. Negative scores indicate improvement in ISI, positive scores indicate increase in ISI.

Time frame: Change from Baseline after 4 weeks
