How At-Home WatchPAT Testing Works
A simple, physician-guided process to evaluate possible sleep apnea from the comfort of your home.
- Schedule an evaluation. Discuss snoring, interrupted sleep, daytime tiredness and medical history during a physician-guided visit, including telehealth when appropriate.
- Receive your WatchPAT device. When a home test is medically appropriate, our clinic can ship the device to your address with setup instructions.
- Sleep in your own bed. Wear the device and its sensors overnight according to the instructions.
- Finish and upload. With the supported WatchPAT cloud-enabled workflow, test data upload through the connected smartphone app after study completion for clinical review. App setup and a working connection are required.
- Review results and next steps. The study is reviewed by qualified clinical personnel; you receive an evaluation and discussion of possible treatment, CPAP/APAP, or further testing.
What a WatchPAT ONE Home Sleep Study Can Measure
WatchPAT ONE records seven types of signals: peripheral arterial tone (PAT), pulse rate, blood oxygen, movement, body position, snoring and chest motion. Its software uses these signals to estimate breathing-related indices (AHI, RDI and ODI), total sleep time and light, deep and REM sleep stages. Central sleep apnea metrics require the appropriate sensor and configuration.
AHI and respiratory events
Estimated apnea-hypopnea index and breathing-related disturbances.
Oxygen levels
Oxygen saturation trends during the night.
Heart rate
Pulse and heart-rate information relevant to the study.
Estimated sleep time
Estimated total sleep duration and sleep efficiency.
Sleep stages
Device-estimated wake, light, deep and REM sleep patterns.
Additional patterns
Depending on model and sensors, snoring, body position and related measurements.
WatchPAT-derived sleep stages and indices are estimates, not equivalent to full in-laboratory polysomnography or standalone diagnoses of other sleep conditions. Available metrics vary by device configuration.
From sleep testing to sleep apnea treatment
After clinical review of your home sleep apnea test, we discuss whether obstructive sleep apnea is present and how severe it may be. For suitable patients, we offer CPAP/APAP therapy and can help coordinate a prescribed machine and ongoing follow-up. Other symptoms or concerning results may require additional evaluation or referral.

Physician-Led Sleep Evaluations in Beverly Hills & Los Angeles
Your assessment may include a detailed medical and sleep history, physical examination, review of medications and relevant laboratory tests when clinically indicated. We evaluate insomnia symptoms, unrefreshing sleep, snoring and possible sleep-related breathing disorders. When appropriate, we coordinate referrals for in-laboratory polysomnography or specialist testing rather than assuming a home test can diagnose every sleep condition. Treatment and follow-up are individualized.

Is a home sleep apnea test right for you?
Home sleep apnea testing is appropriate for selected uncomplicated adults with suspected obstructive sleep apnea. Certain significant medical conditions, possible central sleep apnea, severe insomnia, and negative or inconclusive home tests can require an in-laboratory sleep study instead. Testing is ordered following a clinical evaluation.

Your questions, answered
Do I need to come into the office?
Telehealth evaluation and shipment of an approved home test are available when clinically appropriate and where permitted. A physician will determine whether a home test is suitable.
Does WatchPAT automatically send the results?
With the WatchPAT ONE smartphone-enabled system, recorded study data are transmitted to a cloud platform after completing the test when setup and connectivity requirements are met. The automated report requires clinical review.
What happens if sleep apnea is diagnosed?
We review the results and discuss an individualized treatment plan, including CPAP/APAP when appropriate.
Does the test show REM and deep sleep?
WatchPAT provides estimates of sleep stages such as REM, light and deep sleep, alongside respiratory and oxygen-related measures. These estimates supplement—not replace—medical interpretation.
