采用６２００ＡｕｔｏｂｏｘＤＬ型全自动体积描记仪对３７例健康成人和２８例慢性阻塞性肺部疾病（ＣＯＰＤ）患者用浅快呼吸法和平静呼吸法测定气道阻力（Ｒａｗ）。结果：健康成人及ＣＯＰＤ患者二种方法测出的气道阻力值，浅快呼吸法大于平静呼吸法，二者差异显著或非常显著（Ｐ＜０．０５～０．００１）。气道传导率、比气道阻力、比气道传导率、胸气量差异均无显著性（Ｐ＞０．０５）。由于浅快呼吸法对病人的配合要求较高，年老体弱及严重气道阻塞的患者不易完成。平静呼吸法的测定，不需要对患者进行特别的训练，属生理状态的测试。故我们认为当患者不能完成浅快呼吸法的气道阻力测定时，可用平静呼吸法代替。
Airway resistance (Raw) was measured using the 6200 Autobox DL automated plethysmography apparatus in 37 healthy adults and 28 patients with chronic obstructive pulmonary disease (COPD) by shallow breathing and calm breathing. Results: The airway resistance values measured by two methods in healthy adults and patients with COPD were higher than those of calm breathing, and the difference was significant or significant (P <0.05 ~ 0.001). There was no significant difference in airway conduction, airway resistance, specific airway conduction and chest airway between two groups (P> 0.05). Due to shallow breathing method to patients with higher requirements, frail elderly and severe airway obstruction in patients with difficult to complete. Determination of calm breathing method, does not require special training of patients, is a physiological state of the test. Therefore, we believe that when the patient can not complete the shallow breathing method of airway resistance determination, calmed-breathing can be used instead.
