Acute effects of obstructive sleep apnoea.


The pharyngeal airway narrows when pharyngeal muscle tone decreases. During sleep, partial collapse at this level leads to snoring, and complete collapse to obstructive sleep apnoea [25], Such upper airway incompetence is relatively common: 17% of randomly selected normal British men snore [60]; one in 300 have severe obstructive sleep apnoea and cannot maintain a patent airway in any sleeping posture [60]. In hospital inpatient cohorts the prevalence is greater still. In one middle-aged group with ischaemic heart disease, significant obstructive sleep apnoea affected 14% of the sample [30]. Obstructive sleep apnoea has a range of undesirable acute effects which may be avoided by appropriate management. This review considers the causes of upper airway collapse, its consequences and treatment for the patient in hospital.
