Abstract:
Objective To investigate the characteristics of respiratory impedance in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods The impulse oscillometry(IOS) and polysomnography (PSG) indices were measured in 52 patients with OSAHS, 13 patients with chronic obstructive pulmonary disease (COPD) and 17 healthy persons. Results The levels of R20, total respiratory impedence and central airway resistance in the patients with OSAHS were significantly higher than those in healthy persons (P
