Cath Lab
Qp:Qs, Fick cardiac output, PVR/SVR, Gorlin valve area, O₂ content, VO₂ estimation
Qp:Qs (Shunt Ratio)
Calculates pulmonary-to-systemic blood flow ratio from oxygen saturation data to quantify intracardiac shunts
Oxygen Content (CaO2/CvO2)
Calculates arterial and venous oxygen content and arteriovenous oxygen difference
Fick Cardiac Output
Calculates cardiac output and cardiac index using the Fick principle with optional LaFarge-Miettinen VO2 estimation
PVR / SVR
Calculates indexed pulmonary and systemic vascular resistance with PVR/SVR ratio
Gorlin Valve Area
Calculates aortic or mitral valve area using the Gorlin formula and Hakki simplified method
VO2 Estimation
Estimates oxygen consumption using LaFarge-Miettinen (age >= 3), infant regression, and age-based lookup methods
