HR (Heart rate) Hjertefrekvens (min-1)
SV (Slagvolumen)
Den mængde blod, der pumpes ud ved hver kontraktion = EDV - ESV (50-100 ml)
CO (Cardiac Output) SV (ml) · HR (min÷1)
CI (Cardiac Index)
Hjertets minutvolumen indekseret (l/min/m2);
CO (l/min):BSA (m2)
MAP Middel arterie tryk (65-95 mmHg)
MPAP (PAMP) Middel pulmonal arterie tryk (10-22 mmHg)
CVP (Central venous pressure) Central venøst tryk (0-8 mmHg)
LAP (Left atrial pressure) Venstre atriums tryk (6-12 mmHg)
PCWP (Pulmonary capillary wedge pressure) Pulmonalt indkilingstryk (6-12 mmHg)
EDPAP
(End Diastolic Pulmonary Artery Pressure)
Slutdiastolisk pulmonal tryk
RV (right ventricle) Højre ventrikel
LV (left ventricle) Venstre ventrikel
EDV (End-diastolisk volumen) Slut-diastolisk volumen (fyldning før kontraktion)
ESV (End-systolisk volumen) Slut-systolisk volumen (fyldning efter kontraktion)
LVEDP (Left ventricular end-diastolic pressure) Venstre ventrikels slutdiastoliske tryk
LVEDV (Left ventricular end-diastolic volume) Venstre ventrikels slutdiastoliske volumen
EF (Ejection fraction) (EDV - ESV):EDV = SV:EDV (normalt 55-75 %)
SVR (Systemisk vaskulær resistance) ((MAP - CVP)·80):CO  ( 900-1500 dyn·sec·cm÷5)
PVR (Pulmonal vaskulær resistance) ((MPAP - PCWP)·80):CO  (50-150 dyn·sec·cm÷5)
