Research On Medium-Light Degree COPD Patients Right Ventricular Function Change And The Inhalation Of PGE₁'S Influence On It

Objective: This subject applies Doppler technology to evaluate the systolic and diastolic function of medium - light degree COPD patient's and thus investigates the relevance of medium-light COPD and change of right ventricular function. Based on the observation of treatment effect for medium-light degree COPD patients through different ways of providing PGE₁ and the relationship between medium-light degree COPD patients and their right ventricular function changes, this subject investigates the treatment effect of inhaled and veinal on right ventricular function abnormality and their side effects. 1.1 Research object and approachThe choice of case study is based on disease history, physical characteristics. First, do regular checking for denied patients on electrocardiogram, liver, kidney, blood, urine, then use Italian COSMED PONY Graphic lung function measuring instrument to measure lung function, including Volume capacity (VC), Maximum voluntary ventilation (MVV), Force Volume capacity (FVC), First-second Exhale Volume (FEV₁), FEV₁/FVC (FEV₁%), Functional Residue capacity (FRC), Residue Volume (RV), Total Lung capacity (TLC) and RV/TLC. Sixty medium-light degree COPD patients from November of 2002 to October of 2004 were investigated, 38 of whom were men, and 22 were women, aging from 54 to 72, and with average age of 61.8± 9.6. The COPD judging standard refers to Chinese Medical Association respiratory branch COPD treatment standard (draft). Classify. Subjects chosen were classified as I class and II class according to GOLD.
