 The purpose of this study was to examine the meaning of intraesophageal pressure monitoring in patients with obstructive sleep apnea-hypopnea syndrome(OSAHS). Thirty-three patients(27 men and 6 women; mean age 48.7 years) with OSAHS underwent all-night polysomnography with monitoring of intraesophageal pressure. The number of apnea+hypopnea per hour in stage(1+2) and stage REM was significantly larger than that in stage(3+4). The intraesophageal pressure swings in stage 2, stage 3 and stage 4 were significantly larger than those in the wakened state. These results suggest that the respiratory disorders exist overnight in patients with OSAHS. It is concluded that all-night polysomnography with monitoring of intraesophageal pressure is necessary to make a precise diagnosis of the respiratory disorders in patients with OSAHS.
