2010年6月28日 · A peak RER of ≥1.10 is generally considered an indication of excellent subject effort during CPX, but it is not an indication to stop the test. Achievement of a peak RER <1.00 in a CPX that is terminated by subject request, absent any electrocardiographic or hemodynamic abnormalities, generally reflects submaximal cardiovascular effort but ...

Cardiopulmonary exercise testing (CPET) is a dynamic, non-invasive assessment of the cardiopulmonary system at rest and during exercise. Deficiencies in the CPET-derived variables anaerobic threshold, peak oxygen consumption, and ventilatory efficiency for carbon dioxide are associated with poor postoperative outcomes.

心肺运动试验(cardiopulmonary exercise testing, CPET)是综合评价人体呼吸系统、心血管系统、神经生理以及骨骼肌系统对同一运动应激的整体反应，通过测定人体在休息、运动及运动结束时恢复期每一次呼吸的氧摄取量(VO2)、二氧化碳排出量(VCO2)和通气量(VE)，及心率 ...

2018年1月8日 · Sometimes, the RQ (respiratory quotient) will be reported as the RER (respiratory exchange ratio) in a CPET report. The end-tidal oxygen concentration (PETO2) begins to rise . When the muscles switch to anaerobic metabolism, they are no longer primarily consuming oxygen to make energy.

Cardiopulmonary exercise testing (CPET) is a maximal exercise test with concomitant gas exchange analysis that provides an integrative and comprehensive assessment of physiologic responses to exercise and cardiorespiratory fitness.

Cardiopulmonary exercise testing (CPET) provides assessment of the integrative exercise responses involving the pulmonary, cardiovascular, haematopoietic, neuropsychological, and skeletal muscle systems, which are not adequately reflected through the measurement of individual organ system function.

2022年12月27日 · 心肺运动试验(cpet)是一种可以使研究者同时观察患者的心血管系统和呼吸系统对同一种运动应激的反应情况的临床试验。 因为，呼吸道的气体交换与循环相关联，可以同时反映心排血量、肺血流以及外周O2的摄取，所以同时监测呼吸与循环是可行的。

2024年9月28日 · “CPET是心肺运动评估的金标准，本篇将从基本概念、操作流程、主要指标及意义、临床应用4个方面对CPET做全面的介绍。 是指在逐渐递增的运动负荷下，通过测定人体从静息状态到运动至最大用力状态及再恢复到静息状态过程中的气体代谢、心率、血压、血氧饱和度及心电图等一系列指标变化，记录受试者在测试过程中出现的相应症状，客观反映不同负荷水平下发生的生理病理变化及功能受损程度，从而综合评价心肺等器官系统整体功能和储备能力的一种 …

最初知道心肺运动试验（Cardiopulmonary Exercise Testing, 下文简称CPET）是在知乎看到好几位大V提起，加上最近恰好看了几本跑步相关的书正想提高体能，看到这个试验可以直接测出最大心率和 最大摄氧量 等指标，顿时产生了兴趣（本意是先测一次初始值，训练一段 ...

In particular, cardiopulmonary exercise testing provides precise determination of aerobic capacity, the causes of dyspnea with exertion, and prognosis in patients with systolic heart failure. This review provides basic, practical information about cardiopulmonary exercise testing for …
