便携式肺功能仪临床应用的可行性分析.

Objective To analyze the consistency of pulmonary function parameters measured by portable and Jaeger spirometer and explore the clinical feasibility of the portable spirometer. Methods The pulmonary ventilation functions of 151 subjects were simultaneously measuerd by Jaeger spirometer and Medikro PRO portable spirometer. Eight parameters.i. e. .forced vital capacity (FVC), forced expiratory volume in one second (FEV, ), precentage of predicted forced expiratory volume in one second (FEV, J'cpred) <FEV, FVC.peak expiratory flow (PEP) .forced expiratory flow at 25^: of FVC exhaled (FEF2S ). FEFW and FEF7S. were analyzed and compared using intraclass correlation coefficient (ICC) and Bland-Altman methods. Results No significant biases in the above pulmonary function parameters were found between the Medikro PRO portable spirometer and Jaeger spirometer. The ICC values were as follows:0.988,0. 990,0. 986,0.962,0.969,0. 935.(1. 958,0.935, respectively. More than 92?' of the pulmonary function parameters from these two spirometers were in range of 95^1 consistence interval. Conclusions Compared with Jaeger spirometer.the Medikro PRO portable spirometer has good consistency in the pulmonary ventilation function tests. [ABSTRACT FROM AUTHOR]
