Abstract

The phase difference between mouth flow and chest flow in cases of pulmonary diseases measured using a body box was compared with those in normal subjects. Phase differences in chronic pulmonary emphysema (CPE) and diffuse panbronchiolitis (DPB) patients increased compared to normal subjects, but remained normal in interstitial pneumonitis patients (Normal: 3.76 +/- 1.71, CPE: 10.70 +/- 4.93, DPB: 10.81 +/- 3.15, IP: 3.83 +/- 0.15 degrees). In addition, there was a good correlation with FEV1.0, FEV1.0% and RV/TLC (r: -0.634, -0.610 and 0.803). The analysis of phase differences during rest breathing is clinically useful because it is non-effort dependent and can evaluate the degree of airway disorders.

摘要

使用人体箱测量的肺部疾病患者口腔气流与胸部气流之间的相位差与正常受试者进行了比较。与正常受试者相比，慢性肺气肿（CPE）和弥漫性细支气管炎（DPB）患者的相位差增加，但间质性肺炎患者的相位差保持正常（正常：3.76±1.71，CPE：10.70±4.93，DPB：10.81±3.15，IP：3.83±0.15度）。此外，与FEV1.0、FEV1.0%和RV/TLC有良好的相关性（r：-0.634、-0.610和0.803）。静息呼吸时相位差的分析在临床上是有用的，因为它不依赖于用力，并且可以评估气道紊乱的程度。
