Chest patch sensor to monitor breathing with fingertip sensor for sleep apnea

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study builds on the PranaQ system, adding a chest patch accelerometer to capture respiratory movements alongside the existing fingertip PPG and movement data. The goal is to see if the chest-based respiratory signal can better link apnea events to body position and distinguish central from obstructive apnea. The current validation of the fingertip sensor is strong, but the added respiration data may improve diagnostic accuracy for sleep-disordered breathing. Participants are adults undergoing assessment for sleep apnea at Taipei Veterans General Hospital, with exclusion criteria designed to avoid confounding lung and neurological conditions. No intervention is described beyond sensor data collection during routine monitoring settings.
