[Exercise test in respiratory system].

A ramp exercise test was thought to be adequate especially for evaluation of patients with respiratory system diseases. First, we told about the significances, the methods and apparatus, the arrangements for workload and the matters that demand special attentions of this exercise test. Next, various indices which were obtained during ramp exercise and the estimations of them were explained. Furthermore, we referred to the exercise-limiting factors for patients with COPD and pulmonary fibrosis as symmetrical respiratory system diseases.
