Obstructive sleep apnoea (OSA) is sleep associated disorder of breathing with an episodic reduction or complete airflow obstruction despite an ongoing effort by patient for breathing. OSA seems to affect especially middle-aged and elderly men its prevalence has increased substantially over the last two decades. Few predisposing factors that affect OSA are obesity, craniofacial abnormalities, increasing age, male predilection, family history, smoking, micrognathia, enlarged adenoids and tongue. With rising awareness of OSA and the increasing prevalence of obesity, OSA is increasingly recognized as a major contributor to cardiovascular morbidity including systemic and pulmonary arterial hypertension, heart failure, acute coronary syndromes, atrial fibrillation, and other arrhythmias. Management primarily includes the use of continuous positive airway pressure (CPAP) or Bi-level positive airway pressure (BiPAP) devices during sleep. Alternate options such as mandibular devices and surgical procedures are considered for certain patient populations
