FAQ

What is 1 plasma volume?

  • 1 plasma volume is the volume of plasma contained in the entire circulatory system, which is approximately 4-5 liters in adults.
  • So, if an individual has a plasma volume of 3 liters, it means that their circulatory system contains 3/4 or 60-75% plasma.

How much plasma is in 1 mL of blood?

  • There is approximately 0.55 mL of plasma in 1 mL of blood.
  • This means that the plasma makes up about 55% of the total blood volume, with the remaining 45% made up of red blood cells, white blood cells, and platelets.

How do you calculate plasma volume?

Plasma volume can be calculated using the following formula:

PV = TBV × (1 - Hct)

 

where

  • TBV = Total Blood Volume
  • HCT = Hematocrit Value
