作者分析211份肺功能测定资料,评价呼吸描记法的检出及说明限制性功能障碍的敏感性和特异性。211例中有哮喘26例,COPD 44例,COPD 或哮喘6例,非阻塞性肺病99例,正常人19例,心脏病12例,哮喘缓解期5例。以临床有使肺容积减少,肺顺应性下降的肺疾患病史和体积描记法示 TLC 低于正常范围,而 RV 不增高,SR(比气道阻力)正常作为诊断限制性功能障碍的依据;以降低 FEV_(1.0)/FVC％正常作为呼吸描记法诊断依据。
The authors analyzed 211 lung function test data to evaluate the sensitivity and specificity of the breath-hold assay for detection of restrictive dysfunction. Among 211 cases, there were 26 cases of asthma, 44 cases of COPD, 6 cases of COPD or asthma, 99 cases of non-obstructive pulmonary disease, 19 cases of normal, 12 cases of heart disease and 5 cases of asthma remission. Clinical history and plethora of lung diseases with reduced lung compliance and decreased pulmonary compliance were shown to be below the normal range of TLC while RV did not increase and SR (normal airway resistance) was normal as a basis for the diagnosis of restrictive dysfunction; Reduce the FEV_ (1.0) / FVC% normal as a diagnostic basis of the breath.
