The ramp approach to exercise testing has recently been advocated because it facilitates recommendations made in these guidelines. This article reviews these issues and discusses the evolution of ramp testing which has occurred in the 1990s.

2023年1月29日 · CPET通过测定患者的peakVO 2 、AT、峰值心率、峰值负荷等指标，评估有氧运动能力和心肺储备能力，制定运动处方的目标运动量、目标靶心率等；同时CPET还可检测出运动相关不良反应，如缺血、缺氧、心律失常、血压改变等，评估患者的疾病危险分层，是准确 ...

2010年6月28日 · Ramp protocols typically involve increments in work rate at intervals of <10 to 60 seconds. 19 Regardless of the specific protocol chosen, the protocol should be tailored to the individual to yield a fatigue-limited exercise duration of ≈8 to 12 minutes.

2024年9月28日 · cpet 被认为是评估心肺储备能力的金标准，对有氧运动处方制订有重要的指导价值。 同时，CPET 有助于发现运动所诱发的病理生理变化，提高运动安全性。

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.

2022年1月12日 · CPET is usually performed as symptom-limited cycle ergometry in a sitting position. A continuously incrementing ramp protocol (increase of work rate, e.g., every 2–15 s) or minute-by-minute increments in 5–30 W/min steps to symptom-limited maximum of exercise is used as standard.

The aim of a standard CPET protocol is for the individual to be exposed to a load using a bike ergometer or a treadmill and incrementally increase workload for about 8 to 12 minutes until they can go no further. These are often referred to as an incremental ramp protocol to a volitional maximum. During

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 ...

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. In contrast to exercise ECG, the direct noninva-sive determination of minute ventilation, heart rate and.

2000年8月1日 · This article describes the basic principles and methodology of CPET and provides an overview of important studies that utilized CPET in patients with ESKD, in an effort to increase awareness of...
