    What Is A CPAP Therapy?

    A CPAP is a positive continuous pressure device in the airways that provides air at a predetermined pressure through a mask and is the first line treatment of Obstructive Sleep Apnea-Hypopnea Syndrome. It is used to maintain constant pressure in the airway during the entire respiratory cycle. It acts in a physiological way, fitting tightly over the patient’s nose, like a pneumatic splint, avoiding the collapse of the upper airway during inspiration and expiration. This basically prevents the obstruction of the airway during sleep. Sleep Apnea Obstructive sleep apnea-hypopnea is a common disorder with a slight prevalence in middle-aged people. Several factors have been associated with an increase in its prevalence, such as obesity, age, and arterial hypertension. Among its symptoms are the recurrent collapse of the upper airway during sleep, resulting in repetitive episodes of dyspnea and frequent awakenings, which can lead to daytime drowsiness, decreased attention span and quality of life, and an increase in the prevalence of cardiovascular and cerebrovascular diseases, in addition to an increase in insulin resistance. Treatment with CPAP is indicated in patients with an apnea-hypopnea index greater than thirty episodes per hour, regardless of the associated symptoms. It is also indicated in those who have an apnea-hypopnea index of five to thirty episodes per hour accompanied by symptoms such as daytime sleepiness, cognitive decline, mood changes, insomnia or cardiovascular diseases including high blood pressure, cardiovascular ischemic disease or cerebrovascular accident. So therefore, it is crucial to treat sleep apnea, as doing so can significantly improve a person’s quality of life. Among the effects that allow the use of CPAP to treat sleep apnea are the reduction of sudden nocturnal awakenings, thus improving the quality of sleep and the daytime cognitive activity of the patients. It is not a curative treatment so it should...
