How can i build up blood without transfusion?

User Avatar

Asked by Wiki User

Answer

If you are otherwise healthy, maintaining a good diet is usually all that it takes for your body to make all the blood that you need.

Sometimes, an extra emphasis on iron-rich foods(green leaf vegetables) or even iron supplements can be needed.

Answer

there are four methods that i know of ------Normal Saline and Lactated Ringers Solution, Dextran, Haemaccel, Hetastarch, and in the case of surgery request a "Cell Saver" the intraoperative cell salvage machine suctions, washes, and filters blood so it can be given back to the patient's body instead of being thrown away. One advantage to this is the patient receives his/her own blood instead of donor blood, so there is no risk of contracting outside diseases. Because the blood is recirculated, there is no limit to the amount of blood that can be given back to the patient. The cell saver is also a viable alternative for patients with religious objections to receiving blood transfusions. ---------------------------------------

basically its a mini kidney dialysis machine , it recycles your blood through the machine and back into your body

Why can't blood be donated for a year after a transfusion?

User Avatar

Asked by Wiki User

FDA guidelines require a temporary deferral of one year from date of transfusion for potential donors who have received blood products. This is to minimize the possibility of transfusion-transmitted diseases entering the blood supply. Though unlikely, there is a risk of transfusion-acquired infections with all blood component use. The one year deferral allows any potential disease to be present long enough to be detected by FDA-mandated screening tests.

Why is it dangerous to receive blood of a different type than your own?

User Avatar

yes it is really dangerous to drink blood of different blood type. It is fatal.Incompatible blood causes reactions and that reactions forms blood clotts and it blocks the airways , veins and arteries.

Blood that is drunk follows the same route as all food and drink - into your stomach where it is digested.

What is a hemolytic reaction to a blood transfusion?

User Avatar

Asked by Wiki User

Most severe type, but rare incompatible blood incompatibility in multiple transfusions. Mostlikely to occurs when transfused red cells react with circulating antibody in the recipient with resultant intravascular hemolysis. When a group O patient is mistakenly transfused with group A, B, or AB blood. Patients receiving a major ABO- incompatible marrow or stem cell transplant with sufficient red cell content will likely develop an acute hemolytic reaction. Symptoms are: fever, chills and fever, the feeling of heat along the vein in which the blood is being transfused, pain in the lumbar region, constricting pain in the chest, tachycardia, hypotension, and hemoglobinemia with subsequent hemoglobinuria and hyperbilirubinemia. Prevention: proper identification of patients, pre-transfusion blood samples and blood components at the same time of transfusion.

Can blood transfusions cause HIV?

User Avatar

Asked by Wiki User

Blood transfusions can't cause HIV, but if a carrier of HIV would donate blood, then whoever gets that blood can catch HIV from the donated blood.

It happened a few times when HIV had just started to spread, but nowadays there are testing procedures in place to stop that from happening.
