Supplemental Oxygen and Sleep Related Hypoxemia during Night

Navyasree Nuthalapti

People suffering from obstructive sleep Apnea have intermittent oxygen desaturation with periods of Apnea or hypopnea. Oxygen saturation levels below ninety are considered harmful. Usually Apnea which turn into hypoxemia. Unfortunately, for nasal continuous positive airway pressure (CPAP) or surgical correction for OSA is not used. Three types of sleep-disordered breathing are obstructive sleep Apnea syndrome, Cheyne–Stokes respiration and central sleep Apnea in chronic heart failure, and obesity hypoventilation syndrome, three conditions hypoxia appears to affect body functioning in different ways. Mostly there are molecular and cellular mechanisms that occur in response to SDBrelated hypoxia. During OSAS, most organ, tissue or functional impairment is to the severity of nocturnal hypoxia, OHS is a growing health concern, owing to the worldwide obesity epidemic and OHS morbidities OSAS is defined by symptoms such as excessive daytime sleepiness (EDS) and daytime functioning impairment, occurring during sleep. The scoring of ventilator events includes Apnea, hypopneas and also episodes of increased upper airway resistance that this latter type of event should be included in OSAS.
