Definitions of recorded cardio-haemodynamic parameters
| Parameter | Abbreviation | Unit | Definition |
| Cardiac output | CO | l/min | Amount of blood pumped by the right/left ventricle per minute |
| Cardiac index | CI | l/min/m2 | Cardiac output per body surface area |
| Stroke volume | SV | ml | Amount of blood pumped by the right/left ventricle per contraction |
| Systemic vascular resistance | SVR | dyne·sec·cm−5 | Resistance to the flow of blood in the peripheral circulation (resistance is greatest in the arterioles) |
| Systemic vascular resistance index | SVRi | dyne·sec·cm−5·m2 | Systemic vascular resistance related to the body surface area |
