About this trial
The KPAP vs AirSense 11 with EPR study is a randomized, crossover study in which treatment efficacy will be compared between SleepRes APAP + KPAP and ResMed APAP + EPR. Participants will be chosen from those with a formal OSA diagnosis (following an in-lab polysomnogram, a split-night study or a home sleep apnea test) within the past 2 years and on PAP therapy.
Upon signing an informed consent, participants will be randomized to the order of study and which device will be used first: APAP + KPAP (delivered by a SleepRes device) or APAP + EPR (delivered by a ResMed device). Participants will be blinded to the sequence order. They will then be invited to the laboratory for two overnight sleep studies, one on each treatment device, in the order determined by the randomization. Prior to each overnight, they will have to observe withdrawal of their home PAP treatment for 3 nights. The KPAP drop will be set to the maximum level (i.e., 5 cmH2O), while EPR will be set on 3. APAP from both manufacturers will be set on a 5-20 cmH2O pressure range. The next morning of each sleep study, participants will be administered visual analog scale (VAS) questionnaires to examine subjective sleep quality (1=best sleep quality; 10=worst sleep quality) and, after all studies are completed, a device subjective preference (1=APAP+KPAP was extremely better than APAP+EPR; 10=the opposite).
The study will be single blinded with both the participants (the device will be concealed in the laboratory so that participants will not be able to understand what treatment they are on) and the registered technician scoring the polysomnograms (by an independent scoring partner, Sleep Strategies) blinded to treatment allocation.
