目的 应用运动心肺负荷试验早期检出慢性阻塞性肺疾病 (COPD)运动性低氧血症及运动性肺动脉高压。方法 实验组分为 2组 ,慢性阻塞性肺疾病组 62例 ,正常对照组 3 0例 ,用HPSONS 10 0 0型彩色多普勒超声仪 ,采用三尖瓣返流法于运动前后分别测定 2组受试者的肺动脉收缩压。用Jaeger公司产运动心肺功能仪 ,采用连续递增负荷方案测定最大摄氧量 (VO2 max) ,最大功率 (WATT)等。结果 COPD患者运动能力较对照组明显减低 ,运动后动脉氧分压降低 ,肺动脉收缩压增高 (P <0 .0 5 )。结论 COPD患者运动能力下降 ,运动心肺功能试验可早期发现低氧血症及肺动脉高压。
Objective To detect exercise-induced hypoxemia and exercise-induced pulmonary hypertension in patients with chronic obstructive pulmonary disease (COPD) early in exercise cardiopulmonary load test. Methods The experimental group consisted of two groups, 62 patients with chronic obstructive pulmonary disease group and 30 normal control group. The HPSONS 100 color Doppler ultrasound was used to measure the changes of 2 Group Subjects Pulmonary Artery Systolic Pressure. Using Jaeger company sports cardiopulmonary function meter, continuous incremental load program determination of maximum oxygen uptake (VO2 max), maximum power (WATT) and so on. Results The exercise capacity of patients with COPD was significantly lower than that of the control group. The arterial oxygen tension decreased and the pulmonary systolic pressure increased after exercise (P <0.05). Conclusions The exercise capacity of COPD patients decreased. Cardiopulmonary exercise test could detect hypoxemia and pulmonary hypertension early.
