Abstract

Polysomnography is one of the most useful diagnositc methods for detecting sleep apnea syndrome (SAS). The subjects consisted of 30 adult patients suffering from snoring or sleep apnea. In order to diagnose the location of stenosis and severity of SAS, the mesopharyngeal pressure amplitude (MPA), lowest SaO2 and apnea index (Al) are analyzed. Al< 5 is defined the snoring group, and AI>5 defined the SAS group. The MPA obtained in the SAS group was higher than in the snoring group (P<0.01). The lowest SaO2 obtained in the SAS group was lower than in the snoring group (P<0.01).
