Pulse pressure
systolic presure - Diastolic pressure
compliance
Change in volume / Change in pressure
Stroke volume
EDV - ESV
Ejection fraction
Sv / EDV
Cardiac output
SV x HR
stroke work
VPP x SV
Ventricular pulse pressure
Peak systolic pressure - EDP
Work
Force x distance
Ventricular minute work
SV x HR x VPP
Cardiac output
whole body O2 / artery O2 - vein O2
Mean arterial pressure
CO x TPR
or
SV x HR x TPR
change in pressure
MAP - RAP
Net filtration pressure
(hydrostatic pressure capillaries - hydrostatic pressure in interstitial fluid) - (capillary oncotic pressure - interstitial osmotic pressure)
(pc-pi) - (ttc-tti)
fluid movement
km x (hydrostatic pressure capillaries - hydrostatic pressure in interstitial fluid) - (capillary oncotic pressure - interstitial osmotic pressure)
km=1
flow
pressure in artery - pressure in vein
