Question

How much blood is collected from a person during donation?​

Answer 1

Explanation:

This blood is typically separated into parts, usually red blood cells and plasma, since most recipients need only a specific component for transfusions. A typical donation is 450 millilitres (or approximately one U.S. pint) of whole blood, though 500 millilitre donations are also common.

Answer 2

Answer:

Explanation:

Blood collection from donors weighing 45-55 Kg should be 350 ml blood and from those weighing 55 Kg and above should be 450 ml. The systolic blood pressure should be between 100 and 160 mm of mercury and the diastolic pressure should be between 60-90 mm of mercury.
