The WatchPAT One is a single-use home sleep test worn on the wrist that uses peripheral arterial tonometry (PAT) to detect your breathing events, along with heart rate, oxygen levels, snoring, body position, and sleep stages. It is FDA-cleared and clinically validated with 89% agreement to an in-lab study. It is designed to make sleep testing simpler, removing the need for wires, masks, or lab visits. Just wear it overnight and get accurate results delivered securely to your provider.

No hassle. Just sleep as usual.

This compact device uses advanced sensors to gather key data while letting you move naturally throughout the night. It captures everything needed for a full diagnostic report, including apnea events, snoring, heart rate, and more, all without disrupting your rest. After analysis, you'll receive a detailed medical report and, if needed, a prescription (Rx) for a CPAP machine or other appropriate treatment, without needing to visit a sleep lab.

Wear the device on your non-dominant hand to minimize disruptions while sleeping.
Remove any rings, bracelets, or watches from the test hand to avoid sensor interference.
Make sure the finger probe is inserted fully, with the “TOP” label aligned over your fingernail.
Aim for at least 6 hours of sleep to ensure the test gathers enough data for analysis.
Keep your phone within 5 meters of the device to maintain strong Bluetooth connectivity.
Plug your phone in overnight so it stays charged throughout the test.
Turn off nearby Bluetooth devices to avoid potential interference with the data transmission.
Sleep in your normal position and environment, this test is meant to capture how you sleep naturally at home.
Don’t worry about masks, wires, or lab settings, the device collects all necessary data from your wrist, chest, and finger.
After waking up, press “End Recording” and make sure the data fully uploads before removing the device.
The test automatically tracks snoring, oxygen levels, heart rate, and sleep stages without requiring any input from you.
The results are securely transmitted and analyzed, so your provider gets a full clinical report without delay.
Make sure the adhesive patch on your chest is fully secured for reliable sensor readings.
Don’t reuse the device. WatchPAT One is designed for single use and comes ready to go.
If you’re unsure about setup, follow the included instructions or contact support, setup is simple and only takes a minute.
Avoid sleeping with pets or young children in the bed during the test to reduce accidental disruption.

WatchPAT is a clinical-grade, FDA-cleared home sleep testing system that uses Peripheral Arterial Tonometry (PAT) to evaluate sleep-disordered breathing. The device is worn on the wrist with a finger probe that measures vascular tone and oxygen levels, along with a chest sensor that records snoring and body position. Through these signals, it calculates indices such as the Apnea-Hypopnea Index (AHI), Respiratory Disturbance Index (RDI), oxygen desaturation, heart rate variability, and sleep architecture across light, deep, and REM sleep.

WatchPAT One measures your True Sleep Time, so it calculates your AHI and RDI based on the time you are actually asleep rather than the total time the device was recording. Many home sleep tests use total recording time, which can underestimate the severity of sleep apnea. WatchPAT One also reports sleep stages including REM, the Respiratory Disturbance Index (RDI) with respiratory effort-related arousals (RERAs), and data that helps distinguish central from obstructive events.

Data from the WatchPAT is processed immediately after the session ends, but clinical interpretation is required. Most providers deliver results within 3 to 7 business days, depending on review and scheduling. The report includes diagnostic markers such as AHI, RDI, lowest oxygen saturation, sleep staging distribution, and snoring frequency.

WatchPAT has been validated in peer-reviewed studies against polysomnography (PSG), the gold standard for diagnosing obstructive sleep apnea. Correlation levels for AHI and RDI are high, making it a reliable tool for remote diagnosis. It does not replace full PSG for complex neurological or non-respiratory sleep disorders, but for OSA assessment it provides clinically accurate results suitable for treatment planning.

The WatchPAT setup requires three contact points: the wrist unit, the finger probe, and the chest sensor. The wrist device records vascular and motion data, the finger probe captures arterial tone and oxygen levels, and the chest sensor identifies snoring vibrations and body position. The WatchPAT One app guides the patient step by step, confirming sensor placement and recording readiness before sleep.

Yes. The WatchPAT system is built to capture natural body movement during sleep. Temporary interruptions, such as getting out of bed, do not disrupt the recording. The study remains valid as long as the sensors remain attached until the test completes.

Yes. The WatchPAT One is a disposable home sleep study device intended for a one-night session. The sensors are pre-calibrated for single use and cannot be reapplied. After use, the unit does not require return or disinfection, making the process streamlined for both patient and provider.

The WatchPAT One is FDA-cleared for individuals 12 years and older for its main sleep apnea measures, and 17 and older for the central apnea index (pAHIc). It is used under the direction of a physician.

Yes. WatchPAT is often prescribed to evaluate treatment efficacy after CPAP adjustments, oral appliance therapy, weight changes, or lifestyle interventions. Its ability to measure AHI, RDI, and oxygen saturation remotely makes it practical for longitudinal monitoring without requiring repeated lab visits.

You do not need to bring your own prescription. WatchPAT One is an FDA-cleared home sleep test, and your purchase at Sleeplay includes review of your results by a board-certified physician. After your test, the physician interprets the data and provides a medical report, and if obstructive sleep apnea is diagnosed you receive a prescription (Rx) you can use to obtain CPAP therapy.

Yes. Because the WatchPAT One is classified as a medical diagnostic device, it qualifies under most Health Savings Accounts (HSA) and Flexible Spending Accounts (FSA) as a reimbursable expense. Patients may use pre-tax funds to reduce the overall cost of testing.

Your WatchPAT One report includes the Apnea-Hypopnea Index (AHI) and the Respiratory Disturbance Index (RDI). Sleep physicians generally classify obstructive sleep apnea by AHI as normal (fewer than 5), mild (5 to 15), moderate (15 to 30), or severe (30 or more) events per hour of sleep. RDI can be higher than AHI because it also counts respiratory effort-related arousals (RERAs). Your physician interprets these numbers alongside your symptoms.

For evaluating obstructive sleep apnea at home, the WatchPAT One provides clinically validated data that is often enough for a diagnosis. It does not replace in-lab polysomnography for complex cases or other sleep disorders, and it is not a CPAP titration study. Your physician will advise if an in-lab study is needed.
