The minute ventilation/carbon dioxide production (VE/VCO2) slope reflects the increase in ventilation in response to CO2 production, and thus shows increased ventilatory drive (1).
What does high ve VCO2 mean?
A higher than normal ˙VE at a given ˙VCO2 would thereby indicate the presence of ventilatory inefficiency, although it should be argued on a pulmonary gas exchange basis that increased ˙VE resulting from alveolar hyperventilation does not meet this definition.
What does VE VCO2 mean?
— Definition of abbreviations: 1stVT = first ventilatory threshold; M = men; ˙VCO2 = volume of exhaled carbon dioxide; ˙VE = ventilation; ˙VO2Peak = peak oxygen uptake; W = women. *Values are calculated for men of 75 kg and women of 60 kg weight.
What is VCO2 in respiratory?
Minute ventilation-to-carbon dioxide output (VE/VCO2) slope is the strongest predictor of respiratory complications and death after pulmonary resection. Ann Thorac Surg.
What does the VE/VCO2 slope tell us about cardiac mortality?
The VE/VCO2 slope is a strong predictor of cardiac‑related mortalities in the patients with CHF analyzed. Introduction The minute ventilation/carbon dioxide production (VE/VCO 2 ) slope reflects the increase in ventilation in response to CO 2 production, and thus shows increased ventilatory drive ( 1 ).
What is the normal range of VE/VCO2?
In healthy individuals, the values of VE/VCO 2 slope are usually lower than 30. VE/VCO 2 slope can be increased in both pulmonary and cardiac diseases. Patients with lung disease, for instance, have increased ventilatory requirements for a given level of exercise.
What causes the VE/VCO2 slope to change?
Changes in the VE/VCO 2 slope may be induced by increases in the number of chemoreceptors, the peripheral ergoreceptor response, the ventilatory dead-space and also by the muscle mass engaged in exercise ( 2 – 5 ).
What does VCO2 stand for?
Minute ventilation-to-carbon dioxide output (VE/VCO2) slope is the strongest predictor of respiratory complications and death after pulmonary resection. VE/VCO2 slope is a better predictor of respiratory complications than peak VO2.
