5. Using the following formula, complete the table in preparing red cell suspension with the desired concentration. Show your computations below. % red cell suspension = Amount of washed packed red blood cells Total Volume x 100 Total volume = amount of washed PRBC + amount of NSS to be added Total Volume Amount of washed packed red blood cells 0.10 mL 0.15 mL Solution: 0.20 mL 0.10 mL Desired % 3% 3% 2% 3mL 5mL Amount of NSS to be added 9.80mL
