与任何心肺运动试验一样，对肥胖者进行心肺运动试验（CPET）的目的是确定患者的运动耐受性，并帮助识别和/或区分可能导致运动耐受性的各种生理因素。运动时无法解释的呼吸困难是CPET的常见原因，但这是一个非常复杂的症状。有时肥胖是排除其他可能性的简单答案。因此，区分劳累性呼吸困难的多种临床原因取决于排除可能性的能力，同时识别肥胖患者特有的反应模式。这包括其他健康的肥胖患者，以及可能存在多重心肺功能限制的肥胖患者。尽管在肺功能、代谢疾病和/或心血管功能障碍方面存在明显的局限性，但肥胖可能是运动性呼吸困难的最可能原因。在这篇文章中，我们将回顾健康肥胖成人运动时更常见的心肺反应，特别强调运动时的呼吸困难。肥胖单独和/或作为混杂因素可能导致DOE，需要在CPET期间仔细评估http://ow.ly/Secp305mId2
The purpose of cardiopulmonary exercise testing (CPET) in the obese person, as in any cardiopulmonary exercise test, is to determine the patient's exercise tolerance, and to help identify and/or distinguish between the various physiological factors that could contribute to exercise intolerance. Unexplained dyspnoea on exertion is a common reason for CPET, but it is an extremely complex symptom to explain. Sometimes obesity is the simple answer by elimination of other possibilities. Thus, distinguishing among multiple clinical causes for exertional dyspnoea depends on the ability to eliminate possibilities while recognising response patterns that are unique to the obese patient. This includes the otherwise healthy obese patient, as well as the obese patient with potentially multiple cardiopulmonary limitations. Despite obvious limitations in lung function, metabolic disease and/or cardiovascular dysfunction, obesity may be the most likely reason for exertional dyspnoea. In this article, we will review the more common cardiopulmonary responses to exercise in the otherwise healthy obese adult with special emphasis on dyspnoea on exertion. Obesity alone and/or as a confounding factor may contribute to DOE requiring careful assessment during CPET http://ow.ly/Secp305mId2
