Cardiac index (CI) is a haemodynamic parameter that relates the cardiac output (CO) from left ventricle in one minute to body surface area (BSA), thus relating heart performance to the size of the individual. The unit of measurement is litres per minute per square metre (L/min/m ). See more The index is usually calculated using the following formula: $${\displaystyle {\text{CI}}={\frac {\text{CO}}{\text{BSA}}}={\frac {{\text{SV}}\times {\text{HR}}}{\text{BSA}}}}$$ where CI Cardiac index BSA Body surface area SV Stroke volume … See more The normal range of cardiac index at rest is 2.6–4.2 L/min/m . The cardiac index is frequently measured and used in both See more WebThe presumption is that increased cardiac output will lead to increased oxygen delivery (DO2) and increased tissue oxygenation — but this is not always the case, and may not benefit the patient anyway! ... — A 15 second expiratory occlusion is performed and an increase in pulse pressure or cardiac index predicts fluid responsiveness with a ...
