Wasserman Algorithm Index Calculator

Wasserman Algorithm Index: Explanation and Clinical Context The Wasserman Algorithm Index is a clinical tool used to evaluate cardiopulmonary exercise capacity relative to predicted values based on age and sex. It incorporates measured VO2 peak during exercise testing, resting heart rate, and demographic variables to provide a percentage of predicted maximal oxygen uptake. A value >80% of predicted is generally consi

Weber Classification (CPET Functional Class) Calculator

Weber Classification (CPET Functional Class): Explanation and Clinical Context The Weber classification categorizes patients with chronic heart failure based on peak oxygen consumption (peak VO₂) measured during cardiopulmonary exercise testing (CPET). Class A corresponds to peak VO₂ > 20 mL/kg/min, indicating near-normal exercise capacity and favorable prognosis. Class B (16–20 mL/kg/min) indicates mild limitation o
