Development of a Torso Patch Sensor (C-TraQ) as a Companion Device to a Fingertip Sensor (TipTraQ) for Direct Monitoring of Respiratory Effort

Condition(s) studied

Study summary

The existing PranaQ system utilizes a fingertip sensor that captures PPG(Photoplethysmography) and accelerometer data, and its clinical validation is well-established. While PPG alone has shown effectiveness in diagnosing obstructive sleep apnea, its limited data channels restrict comprehensive evaluation. For instance, it struggles to link apnea events with body position or differentiate between central and obstructive sleep apnea.

To address these limitations, the PranaQ system incorporates new sensors, specifically the chest patch sensor, to monitor respiratory movements via accelerometer signals. The additional respiration signal has the potential to improve diagnostic accuracy for apnea through additional information from respiratory effort.

Eligibility

Primary outcome measure(s)

• Respiratory Rate — one night
  PSG recording estimated respiratory rate as ground truth to compare with the C-TraQ-generated respiratory rate.
• Sleep Position — One night
  Sleep Position measured by PSG as ground truth to compare with C-TraQ generated sleep position
• AHI — One night
  Technician labeled AHI based on PSG signal to compare with PranaQ system's prediction.
