WatchPAT 300: Patient Setup & Instructions for a Successful Sleep Study

The WatchPAT 300 is a gold-standard home sleep testing (HST) device that utilizes Peripheral Arterial Tone (PAT) technology to accurately diagnose sleep-disordered breathing. This instructional video is designed to walk patients through the self-application process to ensure accurate data collection and a comfortable night's sleep.

What is covered in this step-by-step guide:

• Device Overview: Introduction to the WatchPAT 300 components, including the reusable wrist device, the integrated chest sensor (for snoring and body position), and the single-use finger probe.

• Preparation: Guidance on skin preparation, removing jewelry, and selecting the non-dominant hand for the most accurate results.

• Chest Sensor Application: How to properly adhere the snoring/body position sensor to the center of the chest (sternal notch) using the provided adhesive.

• Wrist Device Securing: Instructions on how to tighten the wrist strap—firm enough to stay in place, but comfortable enough for a full night's sleep.

• Finger Probe Activation: The final step—sliding the finger into the PAT probe until it clicks, ensuring the sensor is positioned correctly to monitor blood flow and oxygen levels.

• Starting the Test: How to verify the device is powered on and recording before lights out.

• Morning Routine: Instructions on how to carefully remove the sensors and power down the device for return to the clinic.

Clinical Advantage: The WatchPAT 300 measures Actual Sleep Time (rather than just total recording time), providing a more accurate Respiratory Disturbance Index (RDI) and Apnea-Hypopnea Index (AHI).
