关于呼吸肌在健康和疾病状态时的功能及其变化,人们做了很多工作,认识到呼吸肌疲劳是慢阻肺呼吸衰竭的一个重要因素。现就呼吸肌的一般生理解剖、功能测定和慢阻肺呼吸肌功能变化综述于下。【呼吸肌的一般生理解剖】呼吸肌包括膈肌、肋间肌、胸廓辅助呼吸肌和腹肌。不论是荧光屏下透视还是体积描记法测定,都证明在平静呼吸时,膈肌起主导作用,是完成呼吸泵工作的主要动力来源。肋间
Much work has been done on the function and changes of respiratory muscles in health and disease states, recognizing that respiratory muscle fatigue is an important factor in COPD respiratory failure. Now on the general physiological anatomy of respiratory muscles, functional measurements and respiratory function of COPD changes in the next review. General physiological anatomy of respiratory muscles Respiratory muscles include the diaphragm, intercostal muscles, thoracic auxiliary respiratory muscles and abdominal muscles. Whether fluoroscopy fluoroscopy or plethysmography determination, have proved calm breathing, the diaphragm plays a leading role, is to complete the work of the main source of breathing pump. Intercostal
