Description

Sleep apnea syndrome (SAS), especially obstructive sleep apnea/hypopnea syndrome (OSAHS) can be defined as the coexistence of excessive daytime sleepiness with irregular breathing at night, impairment of cognitive function, mood and personality changes. All patients suspected of SAS should complete an Epworth questionnaire to assess the degree of sleepiness. Polysomnography (PSG) with EEG-based sleep staging is not necessary to diagnose sleep apnea in most patients. Oximetry study may play a role in the initial assessment of OSAHS with limitations. Weight loss should be encouraged in all OSAHS patients. nCPAP (nasal continuous positive airway pressure) is the first choice of therapy for patients with moderate or severe OSAHS. Persistent low CPAP use should lead to a review of treatment. Pharmacological therapy should not be used as first line therapy.
