Abstract: Objective To assess neuromuscular factors influencing the apnea duration in patients with obstructive sleep apnea-hypopnea syndrome(OSAHS). Methods Totally 64 male patients were diagnosed OSAHS by sleep study and were monitored with surface electromyography(EMG). We compared different apnea events with different duration through the percent of compensated EMG value(PCEV). PCEV was determined from awake to early stage of obstructive apnea. Results There was significant difference between PCEVs in different apnea(P<0.05). Conclusion Neuromuscular factors have a certain impact on apnea duration.

Key words: obstructive sleep apnea, electromyography, apnea duration, polysomnography
