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.
