本文对正常人、慢性支气管炎、支气管哮喘、肺心病四组进行肺通气功能、残气检查和气道可逆性的测定,藉以评价支气管舒张剂试验中常用的肺功能指标,探讨气道可逆性因素的判断核准。指出在临床肺通气功能检查中,尤其在以残气检查结果来判断肺功能时,必须考虑气道可逆性因素。并建议把吸入异丙基肾上腺素作为残气测定前的常规准备程序。 In this paper, normal lung function, chronic bronchitis, bronchial asthma, pulmonary heart disease four groups of lung ventilation, residual gas examination and determination of airway reversibility in order to evaluate bronchodilator test commonly used in lung function indicators to explore the airway reversibility factors Judgment of approval. Pointed out that in clinical pulmonary function tests, especially in the determination of residual lung function to determine lung function, we must consider the airway reversibility factors. And recommended that inhaled isoproterenol as a residual gas measured before the routine preparation process.
