This film is designed to illustrate the ever increasing need for blood and blood products. It describes modern methods of collection, testing, handling and distribution to meet not only routine demands but also specialised applications. A heart/lung machine is shown in action during an actual valve replacement operation. Examples of patients being treated with blood components are also featured. Blood components are used in the treatment of many specific conditions. The one 'pint' of blood given by a donor is broken down into its different components which are then used to help a number of patients with differing problems.
Segment 1 A reenactment of a young boy's bike accident is seen. His mother is interviewed about his treatment; he had a ruptured spleen and 3 units of blood were required. The narrator explains that blood is needed for life-saving treatments but also for operations performed to improve quality of life, such as fixing a heart's faulty valve. The operation is seen and the narrator explains how the blood transfusion process works during the surgery. A travelling team from the National Blood Transfusion Service is seen; staff unload a lorry and set up a donor session in a school canteen. The donor register is seen. Time start: 00:00:00:00 Time end: 00:05:11:09 Length: 00:05:11:09 Segment 2 A first-time donor is interviewed by a nurse about any illnesses or medication. A blood test for anaemia is seen, and then the main blood donation. The test for determining blood group is seen; both mechanical and manual tests are shown. A machine tests blood for anaemia and diseases. A haematology department is shown, with researchers examining blood. The narrator explains that advances in technology have brought new possibilities for the blood transfusion service. Time start: 00:05:11:09 Time end: 00:09:59:15 Length: 00:04:48:06 Segment 3 Blood is separated by a centrifuge. The narrator explains blood clotting and the treatment of haemophiliacs; a young boy with haemophilia is seen. His mother keeps factor VIII, a clotting agent, in the home freezer to treat him with. Plasma is seen once it has been separated out; it is frozen into large blocks and sent to a blood products laboratory for research and production of clotting factors and immunoglobulins. Time start: 00:09:59:15 Time end: 00:14:29:02 Length: 00:04:29:12 Segment 4 A donor session is being held at a factory in the north west of England. Foreman Eric Davy is introduced; he has been giving blood since 1940. A man is seen giving plasma only; the red cells are returned to him after they are separated out. He is able to donate plasma more frequently this way. Other uses for blood donations are shown; young girls who were rhesus incompatible with their mothers received anti-rhesus antibody at birth. A burns victim is also seen being treated. The narrator stresses that one unit of blood donated can have many uses, and that 'a little goes a long way'.
