Abstract: This publication is a literature survey on OSA Obstructive Sleep Apnea, carried out with help from reputed physicians. The inputs from Polysomnography Centre are also considered in this study. The major points included in this study are the basic information about OSA, its symptoms’, the diagnosis and treatment options available. Obstructive Sleep Apnea (OSA) is the most common type of sleep apnea and is caused by complete or partial obstructions of the upper airway. It is characterized by repetitive episodes of shallow or paused breathing during sleep, despite the effort to breathe, and is usually associated with a reduction in blood oxygen saturation.

I. INTRODUCTION

Obstructive Sleep Apnea (OSA) is the most common type of sleep apnea and is caused by complete or partial obstructions of the upper airway. It is characterized by repetitive episodes of shallow or paused breathing during sleep, despite the effort to breathe, and is usually associated with a reduction in blood oxygen saturation. These episodes of decreased breathing are called Apneas. Polysomnography is method for diagnosing OSA. In Polysomnography measures respiration, blood saturation (SPO2) and chest’s expansion and compression. As in central apnea, pauses are followed by a relative decrease in blood oxygen and an increase in the blood carbon dioxide. Continuous Positive Airway Pressure (CPAP) therapy on the structural and functional characteristics of the right heart in patients with Obstructive Sleep Apnea (OSA). CPAP treatment would improve right ventricular (RV) function in patients with OSA. When CPAP is used, the titration is performed according to usual manual standardized procedure, which includes CPAP monitoring.
