From: Can perioperative hemodilution be monitored with non-invasive measurement of blood hemoglobin?
Volume kinetics. Curve-fitting of the Hb data from Studies 1–3 as obtained by the (a) invasive and (b) non-invasive measurements. c Schematic drawing of the kinetic model. d The model-predicted versus the measured plasma dilution as obtained with the (d) invasive and (e) non-invasive Hb. f Simulation of the volume expansion of the central body fluid space (the plasma) when 1 L of Ringer’s acetate is infused over 30 min
