How the home sleep test works, what happens after it, and the treatment that follows.
Sleep apnea
Obstructive sleep apnea (OSA) is a condition in which the airway narrows or closes again and again during sleep, so breathing briefly becomes shallow or stops. Each event can pull you out of deeper sleep, usually without you noticing.
Loud snoring, pauses in breathing that a partner notices, waking up gasping or choking, feeling tired after a full night, morning headaches and trouble concentrating. Many people first hear about it from someone they share a room with.
Published estimates put obstructive sleep apnea at 30 to 85 million US adults, with about 80% of cases thought to be undiagnosed (American Academy of Sleep Medicine; Respiratory Medicine, 2025).
Untreated sleep apnea is associated with high blood pressure, heart disease, type 2 diabetes and ongoing daytime fatigue. A home sleep test is a straightforward way to find out whether it is part of the picture.
The sleep test
You order it online and it ships to your door. The test uses the ResMed NightOwl, a small disposable sensor worn on your index fingertip. You set it up with ResMed's myAir app, which walks you through each step with short videos, then sleep as you normally would. In the morning the night's data uploads from your phone.
Peripheral arterial tone (blood-vessel tone in the fingertip), movement, pulse rate and blood oxygen (SpO2), all from one sensor. There are no belts, chest leads or nasal tubes. The recording is scored for breathing events per hour, and ResMed reports that its scoring was validated against in-lab sleep studies (Massie et al., Journal of Clinical Sleep Medicine, 2018).
A smartphone or tablet with the myAir app (iOS 18 or later, or Android 11 or later). Keep it at your bedside, plugged in, while you sleep. ResMed labels the NightOwl for adults 22 and older.
Leave the sensor on. It reconnects to your phone when you're back in bed. If a night doesn't record properly, the app tells you why and adds another night to the study automatically.
No. The NightOwl is fully disposable, with nothing to return, clean or recharge. Throw away each finger wrap after use, and dispose of the sensor as electronic waste when your study is complete.
Yes. The NightOwl is designed to test for obstructive sleep apnea. It does not detect central sleep apnea, and it counts breathing events together rather than separating them by type. If your physician needs more detail, they may recommend a different kind of study.
Your results
A sleep physician reviews and interprets your study. The NightOwl is a prescription device used under the direction of a healthcare professional, and the myAir app doesn't show results on your phone. The report goes to the physician first.
A Somni Sleep Consultant walks you through the physician's report: what it found, what the numbers mean and the treatment the physician recommends. If CPAP is your path, the consultant also helps you choose a mask and get the fit right. Bring any questions you have.
Clinical decisions stay with the physician. Your Sleep Consultant explains the recommendation, answers your questions and guides you through the next steps, but does not diagnose or prescribe.
No. Testing never commits you to a treatment. What comes next depends on your results and the physician's recommendation, and you can take the time you need to ask questions before deciding.
Treatment
CPAP therapy with the React Health G3 X and a fitted mask. The physician recommends treatment based on your study.
React Health's flagship CPAP. It runs in fixed CPAP or AutoCPAP mode from 4 to 20 cm H2O, has an integrated heated humidifier, supports heated tubing and is rated at 28 dB(A). React Health builds it without polyurethane sound-abatement foam, and it carries a five-year warranty.
It depends on your results. CPAP is the most widely used treatment across all levels of severity, and if it isn't right for you, the physician may recommend another treatment. The physician makes the recommendation, and your Sleep Consultant explains it.
Yes. The G3 X is a prescription device. The prescription follows from your sleep study and the physician's review.
The first weeks are an adjustment, and Somni supports you through that period and with resupply as parts wear. The G3 X can also remind you when its filter, tubing and mask are due for replacement.
