Reliability and Physiological Interpretation of Pulmonary Gas Exchange by “Circulatory Equivalents” in Chronic Heart Failure
BACKGROUND: Peak ratios of pulmonary gas‐exchange to ventilation during exercise ([Formula: see text] and [Formula: see text] , termed “circulatory equivalents”) are sensitive to heart failure (HF) severity, likely reflecting low and/or poorly distributed pulmonary perfusion. We tested whether peak...
