Sleep Apnea, Obstructives

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.

The aim is to investigate whether the tissue-preserving tonsil surgery technique is as effective as complete tonsil removal in the treatment of obstructive sleep apnea. The primary outcome measure is the change in the apnea-hypopnea index (AHI) before surgery and at 4-6, 24, and 60 months after surgery.
