Diagnosis of obstructive sleep apnoea-A review

Obstructive sleep apnoea (OSA) is a breathing disorder that takes place during sleep and it involves a decreased or complete cessation in airflow despite the effort to breathe. The diagnosis of obstructive sleep apnoea syndrome (OSAS) requires the combined assessment of clinical features and the assessment of abnormal breathing during sleep. Current evidence indicates that attempts to base the diagnosis of the clinical syndrome on either aspect alone are unreliable. In this review article, we will discuss various modalities to make diagnosis of obstructive sleep apnoea by various ways. Keywords: Sleep Apnoea, Diagnosis, Hypopnoea, OSA, OSAS.
