Chronic obstructive pulmonary disease (COPD) is a common disease. Spirometry is a standard method of assessment of severity of COPD. We evaluate utility of diaphragmatic excursion using ultrasonography in COPD patients and compare this technique with spirometry.
Twenty-six COPD patients and 18 self-reported healthy controls were included in this study. After taking the sociodemographic data, measurement of diaphragm excursion was done using M-mode and B-mode ultrasound. Lung function was assessed by spirometry.
In the COPD group, diaphragmatic excursion was found to be reduced, and it correlates with forced expiratory volume in 1 s (FEV1)/forced vital capacity, whereas it did not correlate with FEV1.
Ultrasound assessment of diaphragmatic excursion is an easy, noninvasive, and readily available diagnostic tool and correlates with spirometry in estimation of severity of COPD.
慢性阻塞性肺疾病(COPD)是一种常见疾病。肺活量测定是评估COPD严重程度的标准方法。我们评估超声检查膈移动度在COPD患者中的应用价值,并将该技术与肺活量测定进行比较。
本研究纳入了26例COPD患者和18例自我报告的健康对照者。收集社会人口统计学数据后,采用M型和B型超声测量膈移动度。通过肺活量测定评估肺功能。
在COPD组中,发现膈移动度降低,且与1秒用力呼气容积(FEV1)/用力肺活量相关,而与FEV1无关。
超声评估膈移动度是一种简便、无创且易于获得的诊断工具,在评估COPD严重程度方面与肺活量测定相关。
