Big CPAP vs. tiny CPAP: which do sleep apnea patients prefer?
NCT ID NCT06564896
First seen Jun 27, 2026 · Last updated Jul 15, 2026 · Updated 2 times
Summary
This study compares how satisfied people with moderate to severe obstructive sleep apnea are with a standard CPAP machine (Airsense 10) versus a portable one (Air-Mini). Fifty adults who are new to CPAP will try both devices and rate their satisfaction. The goal is to see if the smaller, travel-friendly option works just as well and is preferred by users.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CPAP device (continuous positive airway pressure machine)
- What this could lead to
- If this trial succeeds, it could show that a smaller, portable CPAP machine works just as well as a standard one, making treatment more convenient and easier to stick with for people with sleep apnea.
- What could go wrong
- This is a small, early-stage crossover study with only 50 participants, so results may not apply to everyone. The main focus is on user satisfaction, not long-term health outcomes, and the portable device may be less effective for some users.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Aged ≥ 18 years. * Patients diagnosed with moderate to severe OSA (based on AHI classification from sleep study performed). * Patients who are able to understand and answer the questionnaire given. Exclusion Criteria: * Patients who are unable to give consent to the study. * Patients who have been diagnosed with OSA and already on CPAP machine. * Patients who had underlying Obesity Hypoventilation Syndrome (OHS). * Patients who had underlying co-morbidities that worsen apnea symptoms, such as congestive cardiac failure, active malignancy, narcolepsy, active alcohol or drug abuse, treatment-refractory dementia, psychotic illness and active use of drugs that disturb the sleep architecture (i.e hypnotics or stimulants of central nervous system).
