Obstructive Sleep Apnea
Overview
Obstructive sleep apnea (OSA) happens to be the most common of all the other kinds of sleep apnea – with the other types of OSA being mixed sleep apnea and central sleep apnea. Garvey, Pengo, Drakatos and Kent (2015) point out that as a matter of fact, there is evidence to suggest that it is the most common respiratory disorder. This, in the words of the authors, is more so the case given “recent data from the United States and Europe suggesting that between 14% and 49% of middle-aged men have clinically significant OSA” (Garvey, Pengo, Drakatos and Kent, 2015, p. 274).
Breathing Cessations and Severity Assessment
In basic terms, OSA involves periodic breathing cessations during sleep – with the occurrence (and the number) of the said cessations varying significantly. Most cases of OSA go unrecognized, effectively meaning that a very small percentage of those suffering from the same seek medical attention. According to Garvey, Pengo, Drakatos and Kent (2015), the severity of sleep apnea “is usually assessed by the apnea-hypopnoea index (AHI) which is the number of complete (apneas) or incomplete (hypopneas) obstructive events per hour of sleep” (275).
Symptoms
OSA comes about when, during sleep,...
In this case, the relaxation of the muscles in the throat triggers the ‘sagging’ or falling back of either the throat’s fatty tissues and/or tongue into an individual’s airways – effectively obstructing airflow. When this occurs, the brain is signaled to awaken partially, with the result being snorting, choking, as well as gasping as the body attempts to restore airflow. This can occur numerous times during a single night.
There are several symptoms associated with OSA. Some of the more common symptoms identified by Silber, Krahn, and Morgenthaler (2016) include, but they are not limited to, nighttime sweating, loud snoring, morning headaches, high blood pressure, sore throat and a dry mouth in the morning, chocking and gasping after waking up abruptly, decreased libido, as well as excessive sleepiness and fatigue during the day.
Diagnosis
There are several diagnostic tests that could be ordered in primary care. Evaluations are founded on not only the signs and symptoms presented by the patient, but also on various examinations and tests. Physical examination could be inclusive of an observation of the patient’s throat, nose, as well as mouth for any abnormality. Routinely, a blood…
