The VE/VCO2 index defines ventilatory efficiency, for it reflects the interaction between pulmonary ventilation, pulmonary perfusion, and cardiac output, contributing to the prognosis of the patient. An elevated VE/VCO2 index, which is present in patients with cardiac diseases, indicates inefficient ventilation [4. D.
How is ventilatory efficiency calculated?
The regression equation for the lowest VE/CO2 output ratio was 27.94 + 0.108 x age + (0.97 = F, 0.0 = M) - 0.0376 x height, where age is in years and height is in centimeters. We conclude that the lowest VE/CO2 output ratio is the preferred noninvasive method to estimate ventilatory inefficiency.
What is VE in exercise physiology?
Responses to Dynamic Exercise. Pulmonary Responses to Exercise. • Ventilation (VE) increases. VE = tidal volume (VT) + respiratory rate (RR) – Increase in VT (depth of breath)
