Introduction: A growing body of evidence shows the prognostic value of oxygen uptake efficiency slope (OUES), a cardiopulmonary exercise test (CPET) parameter derived from the logarithmic relationship between O(2) consumption (VO(2)) and minute ventilation (VE) in patients with chronic heart failure (CHF).

2017年6月30日 · A higher OUES (steeper slope) represents more efficient oxygen being delivered in the body; while a lower OUES (more flat slope) represents a higher amount of ventilation required in response to a given oxygen uptake (Figure 1A and 1B). 4 Predicted values for OUES were calculated from the equations introduced by Hollenberg and Tager 17 In men ...

2023年8月15日 · The oxygen uptake efficiency slope (OUES) is another CPET parameter proposed to assess severity of illness in patients with HF. The OUES is the slope of the relation between VO 2 and log VE. A steeper slope, or larger value for OUES, equates to more efficient utilization of oxygen at any given rate of ventilation.

2024年6月13日 · The oxygen uptake efficiency slope (OUES) serves as a prognostic measure derived from cardiopulmonary exercise testing (CPET) in heart failure. Various equations are utilized as references to calculate predicted OUES (1,2).

As an alternative, the oxygen uptake efficiency slope (OUES) is a reproducible and reliable parameter measured during CPET, which does not require a maximal exercise to be interpretable. This study aimed to evaluate the OUES of a large cohort of children with CHD, in comparison with healthy controls.

2020年3月9日 · Several significant CPET threshold values were identified in detecting a forced expiratory volume in 1 second (FEV1) < 1.6 L: 1) oxygen uptake efficiency slope (OUES) < 1.3; and 2) circulatory...

2023年5月24日 · Oxygen uptake efficiency slope (OUES) measured by cardiopulmonary exercise testing (CPET) is a measure derived from submaximal oxygen uptake values and has prognostic significance in heart failure patients. Measured values are compared to reference standards for an adequate individual assessment.

2011年10月1日 · A growing body of evidence shows the prognostic value of oxygen uptake efficiency slope (OUES), a cardiopulmonary exercise test (CPET) parameter derived from the logarithmic relationship between O 2 consumption (VO 2) and minute ventilation (VE) in patients with chronic heart failure (CHF).

2022年6月1日 · Five CPET parameters were calculated: vO2 max, oxygen uptake efficiency slope (OUES), VE/vCO2 Slope, VE/vCO2 min, and VE/vCO2 max. The relationship between CPET parameters and postimplantation outcomes was evaluated with multivariable analysis.

Our study showed that OUES in the 6MWT had the strongest correlation with OUES in the CPET and was associated with peak VO 2 in the CPET, regardless of LVEF. Using the formula obtained through the linear regression analysis, the peak VO 2 value of the CPET can be estimated through the OUES in the 6MWT: Peak VO 2 in CPET = 13.446 + 0.004 x (OUES ...
