Hemodynamische parameters:
- body surface area (nl 1.6-1.9 m 2 ): BSA = [lengte (cm) + gewicht (kg) – 60] / 100
Centraal veneuze druk CVD 1 – 6 mmHg
Pulmonary capillary wedge pressure PCWP 6 – 12 mmHg
Cardiac index CI 2.4 - 4.0 L/min/m 2
Stroke volume index SVI 40 – 70 mL/beat/m 2
Li ventrikel stroke work index LVSWI 40 – 60 g.m/m 2
Re ventrikel stroke word index RVSWI 4 – 8 g.m/m 2
Re ventrikel ejectie fractie RVEF 46 – 50 %
Re ventrikel eind diastolisch volume RVEDV 80 – 150
Systemisch vasculaire resistance index SVRI 1200 – 2400 dynes.sec.m 2 /cm 5
Pulmonale vasculaire resistance index PVRI 200 – 400 dynes.sec.m 2 /cm 5
Pulmonary artery pressure PAP syst: 15-30; diast: 6-12 mmHg
Re ventrikel druk RVP syst: 15-30; diast: 0-4 mmHg
Re atrium druk RAP 0 – 4 mmHg
Gemengd veneuse zuurstof saturatie S VO2 70-75%
Oxygen delivery D O2 500 – 600 mL/min.m 2
Oxygen uptake V O2 110 – 160 mL/min.m 2
Oxygen extraction ratio O 2 ER 20-30%
CVD = RAP = RVEDP = 1-6 mmHg
PCWP = LAP = LVEDP = 6-12 mmHg
CI = CO / BSA
SVI = CI / Heartrate
(stroke volume index: volume ejected by the ventricles during systole)
RVEF = SV / RVEDV
(ejectiefractie: fractie van ventriculair volume dat geejecteerd wordt tijdens systole)
LVSWI = (MAP – PCWP) x SVI x 0.0136
(LVSWI: work performed by the Ve to eject the stroke volume into the aorta)
RVSWI = (PAP – CVD) x SVI x 0.0136
(RVSWI: work needed to move the stroke volume across the pulmonary circulation)
SVRI = (MAP – RAP) x 80 / CI
PVRI = (PAP – PCWP) x 80 / CI
D O2 = CI x 13.4 x Hb x S aO2
V O2 = CI x 13.4 x Hb x (S aO2 – S vO2 )
O 2 ER = V O2 / D O2 x 100
