Instructions for calculating the residual concentration (%) after a non-isovolumetric plasma exchange

Cell Text to be entered
A1 Kinetics of continuous flow plasma exchange – non-isovolumetric
A3 Patient’s blood volume (mL)
A4 Patient’s initial venous haematocrit (%)
A5 Correction factor for the body haematocrit
A6 Removed volume (mL)
A7 Ratio between the infused and the removed volumes
A9 Patient’s plasma volume (mL)
A10 Removed volume (%)
A11 Residual concentration (%)
Value to be entered
B3 Blood volume of the patient (mL), e.g. 4,500
B4 Initial haematocrit of the patient, e.g. 30
B5 Correction factor for body haematocrit: 0.91
B6 Volume of plasma removed (mL), e.g. 3,000
B7 Ratio between the infused and the removed volumes, e.g. 0.8
Formula to be entered
B9 =B3*(1−B4/100*B5)
B10 =B6/B9*100
B11 =POWER(1+((B7−1)*B6/B9), 1/(1−B7))*100
