Obstructive sleep apnoea (OSA) is a sleep disorder characterized by a partial or complete cessation of upper airway during sleep. It is estimated that approximately one billion individuals between the ages of 30 and 60 are affected by sleep apnoea worldwide [1]. Currently, the apnoea-hypopnoea index (AHI), which represents the number of apnoeas and hypopnoeas per hour during sleep, is commonly used to diagnose OSA and assess its severity. These respiratory events are typically accompanied by oxygen desaturations.
