老年哮喘和慢性阻塞性肺疾病患者的呼吸阻抗临床探讨

To investigate the clinical geriatric asthma and respiratory impedance in patients with chronic obstructive pulmonary disease

目的:通过探讨老年哮喘和慢性阻塞性肺疾病呼吸阻抗,旨在为提高患者生活质量提供理论依据。方法:选择老年哮喘患者36例作为哮喘组,老年慢性阻塞性肺疾病患者36例作为COPD组,再选择同期接受检查的健康体检者作为对照组,应用常规通气功能、脉冲震荡法对三组患者呼吸阻抗测定,记录FEV1、FEV1/FVC和R5-R20、Rp、Fres。结果:哮喘组和COPD组通气功能指标与对照组比较显著降低,哮喘组和COPD组气道阻力R5-R20、Rp、Fres显著高于对照组,差异有统计学意义(P<0.05)。结论:哮喘和慢性阻塞性肺疾病患者气道阻力显著增加,且呼吸阻抗与通气功能呈一定相关性。

Objective To investigate the elderly by breathing in asthma and chronic obstructive pulmonary disease resistance,and to provide the theory basis for improving the quality of life of the patients.MethodsSelect treated 36 cases of elderly patients with asthma as asthma group,elderly patients with chronic obstructive pulmonary disease in 36 cases as COPD group,and then select the same period examined subjects served as the control group,the three groups of patients with respiratory impedance measured using conventional ventilation function,pulse shock method,FEV1,FEV1/FVC and R5-R20 record,Rp,Fres.Results The asthma group and the COPD group of ventilation function index compared with the control group decreased significantly,asthma group and the COPD group of R5-R20,Rp,Fres,airway resistance was significantly higher than that of control group,and there was significant difference（P〈0.05）.Conclusion Asthma and chronic obstructive pulmonary disease patients airway resistance increased significantly,and the respiratory impedance were associated with ventilation function.
