KPAP vs EPR for Comfort

Starting soon · Not applicable

Conditions studied: Obstructive Sleep Apnea

In brief

The KPAP EPR Home is a randomized, crossover study in which subjective comfort will be compared between SleepRes APAP + KPAP and ResMed APAP + EPR. Participants will be individuals with newly diagnosed OSA who have not previously tried any PAP treatment (PAP-naïve). Upon signing an informed consent, participants will be randomized to receiving either APAP + KPAP (delivered by a SleepRes device) or APAP + EPR (delivered by a ResMed device) for home use. Participants will be asked to use the devices (in the order of randomization) for 4 days each, with 3 days of washout in between. Participants will be blinded to the sequence order, even though they will receive machines that are not identical at each treatment. The KPAP drop will be set to the maximum level (i.e., 5 cmH2O), while EPR will be set on 3. APAP will be set on the full pressure range (i.e., 5-20 cmH2O). After each period, each individual will be asked to rate their device preference according to a 10-point visual analog (VAS) scale (i.e., 1=extremely uncomfortable treatment; 10=extremely comfortable treatment). After usage, the devices will be returned to the office and device data will be downloaded.
