The two most common stress tests for the diagnosis of lung diseases are the determination of the 6-minute walk distance and cardiopulmonary exercise testing. Six-minute walk distance at this simple test to be performed is determined the maximum walking distance, patients can travel within 6 minutes at their own pace. This test measures the overall functional capacity, but does not provide specific information about the individual systems that are involved in physical performance, represent (i. E., Heart, lung, haematological, musculoskeletal system). The patient’s effort is not detected. This test is used before and after lung transplantation and lung volume-reducing operations of assessing the response to therapeutic interventions, and pulmonary rehabilitation and for the prediction of mortality and morbidity in cardiac and pulmonary vascular disease. Spiroergometry This automated function test allows an analysis of respiratory gas exchange for each Atemzugund of cardiac function at rest and during a period defined load. The load is then increased continuously until symptoms force them to abort. It collected data on respiratory flow, O2 consumption, CO2 production and heart rate and used for the automated calculation of other variables. Exhaust gas can be collected. The loading takes place on a treadmill or bicycle ergometer; the latter might be preferable, since the power can be measured directly and the test is less affected by obesity. Primarily, the spiroergometry determines whether patients have normal or reduced maximum physical exercise capacity (VO2max) and points – if so actual attention to the possible cause. CPET is used to determine which organ system is the extent to which participate in the exertion and power reduction. In addition, this function test to detect early or subclinical stages of disease is more sensitive than less detailed test procedures alone. Clinical applications include determining the efficiency for the diagnosis of a heavy damage Preoperative Assessment The determination as to whether Dyspnoesymptome from cardiac or pulmonary problems in patients revealed who are suffering from both organ systems. Selection of candidates for a heart transplant assessment of prognosis in selected diseases (eg. As heart disease, pulmonary vascular disease, and cystic fibrosis) Furthermore serves CPET to measure the therapeutic success of operations and can be decision support for regulation of physical workouts as part of rehabilitation programs. For therapy or follow-ups can take place continuously increasing load steps, such as are used in the maximum spiroergometry a, be helpful for 6 min maintained constant load level, which corresponds to about 50-70% of the maximum load. Repeated measurements over time at this constant strain level provide comparable data, and are sensitive to detect improvements and degradations of cardiopulmonary function. In spiroergometry different variables are collected, none of which alone could reveal the cause of limited efficiency. Instead, an integrated approach is used, be included in the clinical data, the development direction under load and the detection of underlying physiological response patterns in the evaluation.
