WebBy using the formula: (LVEDD - LVESD / LVEDD) x 100 we get the percentage of size differences of the left ventricle as a parameter of how well the left ventricle is contracting itself and therefore reduces the size during systole. Values > 28% are considered to be normal. It was very popular although there are some important pitfalls. WebCardiac output is therefore calculated using the formula: Cardiac output = Oxygen consumption / Arteriovenous oxygen gradient; Normal values: Normal cardiac output is 4-8 L/min; Normal cardiac index is 2.5-4 L/min/m²; Normal stroke volume is 60-100 ml/beat; Normal stroke volume index is 33-47 ml/beat/m²

It relates the cardiac output (CO) from the left ventricle in one minute to the BSA called body surface area. So, its measurement is litres per minute per square meter and written as L/min/m2. The normal range for cardiac index (CI) is 2.5 to 4 L/min/m2.

WebCardiac index. Cardiac index ( CI) is a haemodynamic parameter that relates the cardiac output (CO) from left ventricle in one minute to body surface area (BSA), [1] thus relating heart performance to the size of the individual.
