About WatchPAT 400
WatchPAT 400 provides a streamlined, app-connected home sleep apnea testing (HSAT) solution that improves clinical workflow and patient compliance. It preserves the clinical accuracy of WatchPAT technology while enabling cloud transmission of results for immediate access.

Efficient Experience

• Immediate access to study results via secure cloud transmission
• Proven WatchPAT clinical accuracy

Simple Compliance

• 3 points of contact for reliable signal acquisition
• Intuitive setup guided by the WatchPAT app

Innovative Design

• SleePATh functionality integrated with the WatchPAT app
• Streamlined workflow to accelerate clinical decision-making

Accurate

• 7 channels with 4 respiratory indices
