Blood transfusions lifespan what is blood cancer called

Human blood is made of a fluid called plasma. Plasma carries red and white blood cells and platelets. Each part of blood has a special function. These parts can be separated from each other. Bone marrow, the soft, spongy material in the center of the bones, makes most of the body’s blood cells. Here is a look at each part of the blood, and why it might be transfused:

Red blood cells. These cells carry oxygen from your lungs to other body organs. They also carry carbon dioxide back to the lungs to be breathed out (exhaled). The body needs a certain number of these cells to work well. Bleeding due to injury, surgery, or disease may cause a low red blood cell count. This is the most common type of transfusion.

White blood cells. These cells fight infections by destroying bacteria, viruses, and other germs.


White blood cells are rarely transfused. They are often set aside as a short-term (temporary) treatment for people with a low white cell count and severe infection that has not responded to antibiotics.

Platelets. These little pieces of blood cells help blood to clot. Your body may not make enough platelets. This might be due to bone marrow disorders, increased destruction of platelets, or medicines such as chemotherapy. Platelets may be transfused before a procedure that may cause a person with a low platelet count to bleed.

Plasma. This fluid carries the blood cells all over the body. It contains proteins, vitamins, and minerals. Some of the proteins also help blood to clot. Plasma or fresh frozen plasma can be transfused in people who severely lack certain parts of the blood that help with clotting. What are the risks of a blood transfusion?

Most hospitals use blood from volunteer donors. These donors are not paid for giving blood or blood products. Each blood donor must answer medical history questions and have a limited physical exam before being accepted as a donor. Donated blood is carefully tested, which lowers the chances of transfusion-related infections. Donated blood is tested for:

Transfusion reactions can occur even if the donated blood is the right blood type. Transfusion with blood that is the wrong type can be fatal. But this is unlikely to occur because medical workers check blood multiple times. Other types of blood donation

Directed blood donation. This is when friends or family donate blood for a certain person. This blood is set aside for that person’s use. This type of donation requires a prescription and must be scheduled in advance. Direct blood donations go through the same testing as other volunteer donations. If the person does not use this donated blood, it may be made available for someone else.

Donating blood for yourself (autologous donation). This is your blood that you donate for your own use. It is set aside and can be transfused back into your own body if needed for a later, planned surgery. This type of donation requires a prescription from your provider and is scheduled in advance. It does not go through the same testing as other blood donations. If you don’t use the blood, it is thrown away. How do I get ready for a blood transfusion?
