Every hospital needs large supplies of blood for transfusions. It is given by donors.

Before giving blood, the donor is given tests to determine his blood group and make sure he is not suffering from certain diseases. When this has been done his blood can be taken.

First he lies down with his arm on a pillow. Next the nurse puts the cuff of the sphygmomanometer around his upper arm, and inflates it to compress the veins. At this stage she cleans his skin with ether and inserts the needle into a vein. As she does this the blood begins to flow into a bottle until it is full. Meanwhile the donor opens and closes his hand to increase the flow.


As soon as the bottle is full the nurse takes off the sphygmomanometer and withdraws the needle. Finally, she puts a dressing on the donor’s arm. The blood is immediately labeled and refrigerated.
