  1. Infusion 70 kg adult

  2. Sample Problem A subject weighs 80 kg. Calculate the volumes of the ICF, ECF, interstitium and plasma. Total Body Water: 80 kg x 0.60 = 48 liters ICF: 80 kg x 0.40 = 32 liters ECF: 80 kg x 0.20 = 16 liters Interstitium: 16 liters x 0.75 = 12 liters Plasma: 16 liters x 0.25 = 4 liters
