Physiological Factors Relevant to Exercise Tests in Pulmonary Rehabilitation of COPD Patients

Abstract

Chronic obstructive pulmonary disease (COPD) is a major cause of chronic morbidity and mortality in the world special in United States. Patients with COPD often complain of dyspnea and fatigue in exercise intolerance, also significantly impede quality of life of them. Main propose in this study is comparison all of Physiological Factors in reports and results of researches in relevance to Cardiopulmonary Rehabilitation in COPD patients with exercise approach. In this study with style of Theoretical basic research and data calculate of digital resources, PubMed, Science direct, Scopus, Guidelines of ERS/ATS with Bibliographic method. Our approach is comparison all of physiological factors in investigations relevant to exercise tests in cardiopulmonary rehabilitation of COPD patients include: VO2Max, VCO2, VE, HR, FEV1, FVC, assessment of perceptual responses e.g. dysfunctions in muscle, dyspnea, leg discomfort, fatigue and such as exercise-related arterial oxygen desaturation, dynamic hyperinflation and limb-muscle strength. In many researches more improved of VO2max in Cardiovascular limitation than Ventilate limitation in COPD patients. In Cycle ergometer testing, COPD patients had less in elicit O2 desaturation that might occur in during lung ambulation. By using maximal incremental treadmill exercise test protocols can be developed and increased tolerance exercise in COPD patients. Treadmill testing have more physiological limitations than cycle ergometer and COPD patients often in treadmill tests have more limiting factors: dyspnea and coughing.
