The cardiac index (HI) indicates the ratio of cardiac output (HMV) to body surface area (KO) and can be calculated using the following formula:
KI = HMV / body surface area l / min / m2 (Lapp 2014)
The lower normal limit at rest is > 2.5 l / min / m2 (Herold 2020).
Decreased values of < 2.2 l / min / m2 are a criterion for septic shock (Krist 2024)
