深吸气量测定在慢性阻塞性肺疾病患者中的临床意义

目的探讨深吸气量测定在慢性阻塞性肺疾病（COPD）患者的临床应用价值。方法对61例COPD急性加重引起呼吸困难患者在其症状改善前、后进行肺功能测试,并比较各项肺功能指标的变化。结果在各项肺功能指标中,深吸气量（IC）、用力肺活量（FVC）、第一秒用力呼气量（FEV1）均有改善。IC的平均改善率（20.36±0.59）%,其中改善率≥10%的占70.5%（43/61）;FEV1平均改善率（11.88±0.11）%,其中改善率≥10%的占34.4%（21/61）。结论深吸气量测定可以作为评价COPD患者呼吸困难改善程度的指标。

The clinical implication of inspiratory capacity in patients with chronic obstructive pulmonary disease

Objective To evaluate the clinical implication of inspiratory capacity in patients with chronic obstructive pulmonary disease （AECOPD）.Methods Pulmonary function tests were performed in 61 patients with acute exacerbations of chronic obstructive pulmonary disease （AECOPD）,compared the variation of pulmonary function indexes before and after symptom improvement.Results In those pulmonary function indexes,such as IC,FVC and FEV1 increased after symptom improvement.The reversibility in IC was（20.36 0.59）%.A reversibility great or equal to 10% in IC was 75.7% （43/61） of the patients,but The reversibility in FEV1was （11.88 0.11）,A reversibility great or equal to 10℅ in FEV1 was 34.4% （21/61） in 61 the patients.Conclusion Inspiratory capacity is a index to evaluate the level of pulmonary function for patients with chronic obstructive pulmonary disease
