Fuzzy reasoning Clinical Decision Support for manual titration of Positive Airway Pressure Support and Oxygen supply in patients with Obstructive Sleep Apnea

摘要

Continuous Positive Airway Pressure Support (CPAP) devices are commonly used in Home Care for treating patients with sleep breathing disorders. This paper presents a Clinical Decision Support (CDS) model for adult patients with Obstructive Sleep Apnea, advising manual titration of positive pressure support and Oxygen supply. The CDS collects data from wireless devices, namely Arterial Oxygen Saturation (SaO2) and upper airway flow & pressure, and utilizes a Fuzzy logic (FL) algorithm for producing advice on the level of pressure support and oxygen supply according to patient's needs. CDS suggestion on pressure supply closely followed clinical guidelines (mean rmse 3.16 cm H2O).
