A comparative study of accuracy in major adaptive filters for motion artifact removal in sleep apnea tests.

ABSTRACT: Sleep apnea is probably the most common respiratory disorder; respiration and blood oxygen saturation (SpO₂) are major concerns in sleep apnea and are also the two main parameters checked by polysomnography (PSG, the gold standard for diagnosing sleep apnea). In this study, we used a simple, non-invasive monitoring system based on photoplethysmography (PPG) to continuously monitor SpO₂ and heart rate (HR) for individuals at home. Various breathing experiments were conducted to investigate the relationship between SpO₂, HR, and apnea under different conditions, where two techniques (empirical formula and customized formula) for calculating SpO₂ and two methods (resting HR and instantaneous HR) for assessing HR were compared. Various adaptive filte
