The article reviews the course of VO2 in the phase of recovery kinetics of oxygen uptake (VO2rec) cardiopulmonary exercise test. VO2rec kinetics cannot be completely defined using a single parameter. The article describes the three most frequently used methods: %VO2-REC2, T1/2 VO2rec and TC VO2, and provides detailed procedures of their analysis. The three aforementioned parameters are also at the heart of our classification of VO2rec. The method %VO2-REC2 is an essential one, in our view, since its prognostic significance is proven and it can be also easily applied only based on a data record of the cardiopulmonary exercise test. %VO2-REC2 should be seen, together with VO2peak, VE/VCO2 slope and exercise oscillatory ventilation (EOV) - as one of the four elementary prognostic markers establishing an advanced chronic heart failure.Key words: cardiopulmonary exercise test - chronic heart failure - prognosis - recovery kinetics of oxygen uptake.
本文回顾了心肺运动试验中摄氧量恢复动力学（VO2rec）阶段VO2的变化过程。VO2rec动力学不能用单一参数完全定义。本文描述了三种最常用的方法：%VO2-REC2、VO2rec的T1/2和TC VO2，并提供了详细的分析步骤。上述三个参数也是我们对VO2rec进行分类的核心。我们认为，%VO2-REC2方法至关重要，因为其预后意义已得到证实，而且仅基于心肺运动试验的数据记录就可以轻松应用。%VO2-REC2应与VO2峰值、VE/VCO2斜率和运动振荡通气（EOV）一起，被视为建立晚期慢性心力衰竭的四个基本预后标志物之一。关键词：心肺运动试验-慢性心力衰竭-预后-摄氧量恢复动力学
