Ejection fraction
From end-diastolic and end-systolic volume (Simpson) or from diameters (Teichholz)
Scientific basis
Body surface area
For indexing, body surface area is calculated by Mosteller from height and weight (body surface area rule set); the pediatric echo recommendations (Lopez 2010) mostly use Haycock for z-scores – for cardiac index and stroke volume index, the choice of formula is of minor importance.
Calculation aid for healthcare professionals: the calculator reproduces what the sources cited assign to the inputs. Clinical assessment and every treatment decision remain with the treating physician. Inputs and results are not stored.
