【摘要】：目的:观察稳定期慢性阻塞性肺疾病(COPD)患者的恒定功率运动表现与动态过度充气间的相互关系。方法:对30例中度以上稳定期COPD患者进行常规肺通气功能、80%Wmax恒定功率自行车运动测试,分析运动耐受时间、呼吸困难程度、最大摄氧量量及最大公斤摄氧量百分比与深吸气量百分比变化值之间的相互关系。结果:COPD患者均出现不同程度的运动能力下降,且在恒定功率运动中伴随显著的动态过度充气;相关分析提示,恒定功率运动最大公斤摄氧量百分比与动态过度充气百分比呈负相关(r=-0.480,P=0.007),而与静息深吸气量百分比呈正相关(r=0.667,P=0.01)。结论 :动态过度充气可能是COPD患者恒定功率运动受限的重要影响因子,抑制动态过度充气可能有助于改善患者的恒定功率运动表现。
[Abstract]:Objective: To observe the relationship between constant power exercise performance and dynamic hyperinflation in patients with stable chronic obstructive pulmonary disease (COPD). Methods: 30 patients with moderate and above stable COPD were performed routine pulmonary ventilation function, 80%Wmax constant power bicycle exercise test, and analysis of exercise tolerance time, dyspnea and maximum oxygen uptake The relationship between the volume and the maximum percentage of oxygen uptake and the change in the percentage of deep inspiratory volume. Results: COPD patients all had varying degrees of movement ability and were accompanied by significant dynamic hyperinflation in the constant power movement; correlation analysis suggested that the maximum oxygen uptake percentage of the constant power movement and the dynamic overcharge were observed. The percentage of gas was negatively correlated (r=-0.480, P=0.007), but positively correlated with the percentage of resting deep breathing (r=0.667, P=0.01). Conclusion: dynamic hyperinflation may be an important factor in the constant power movement restriction of COPD patients. Inhibition of dynamic hyperinflation may help to improve the patient's constant power movement performance.
