Blood Transfusions

Blood is stored within a blood bank because it will keep the blood fresh and preserved until it is sent off to hospitals that need it for patients that are in critical condition. There is a constant demand for blood donations as hosptials always need to have an ample supply to treat patients, so blood banks help out by by always increasing their supply whenever they can so that they can continously deliver them to hospitals.

Most areas will have a blood bank in their vicinity that can be contacted with regards to any questions that concern this topic.

No, of course not. Blood from different species does not work together at all because the immune system recognizes blood from a difference species as being foreign and rejects it.

because all the contents of the blood could not travel through bigger number gauges or lesser diameter hypodermic needles

This is not a routine practice, but it is desirable when transfusing animmunocompromised patient, as the T-lymphocytes in the transfused blood may otherwise provoke a graft-versus-host reaction. Low-dose ionising radiation inactivates the T-lymphocytes without harming the other blood components.

Radiation has also been proposed as a method of sterilising the blood units, but much higher doses, which are not necessarily well tolerated by the blood cells, are needed for this purpose.

Well, you can´t be white if you have interracial marriages in your ancestors, so the questions is quite illogical. But anyways a blood transfusion doesn´t have anything to do with what your children will inherit from your genes... for example, if you are a AB+ and receives a O- blood transfusion, it´ll have nothing to do with your future children, it´s impossible to a AB+ to conceive a O- child, and vice-versa.

This varies depending on trust/hospital policy.

My policy: Blood can be out of the fridge for 3 hours but each unit must be given within 30 minutes. Any blood that is not used, opened or not must be returned to the blood bank.

Most patients will not require transfusion of blood components if 500 ML of whole blood is lost. However, depending on the patients underlying medical condition and cardiovascular/respiratory reserve, even small amounts of blood loss may lead to significant reactions requiring replacement.

the inertia will cause the blood to flow down to the tip of the finger and make it easier for us to collect sufficient blood for the experiment.

In medicine, women prefer to have a woman overseeing their medical care, and men prefer male doctors. There are no religious objections to blood transfusions, however Hindu people believe in reincarnation with a cause and effect relationship.

Not a good Idea. When it comes to someone wanting bank account transfer, its usually fraudulent.

Well, not if it is your own blood, that would defeat the whole purpose. But, it might be possible. It would take a decent bit of blood to even make a cupful and it is not easy to digest. People, with stomach or intestinal problems that cause bleeding, often have upset stomachs from the blood. So, perhaps it might not make that much of a difference. Interesting question.

The Kell Antigen system is a system of antigens on the surface of human's red blood cells. The antigens are the distinguishing factor in the human blood type and also important for the immunology of the human body.

Most doctors do not give lasix before a transfusion, but give it between 2 units of PRBC to prevent fluid volume overload.

To learn the answer of the above question first we have to know about the blood characteristics.There are four major types of blood A, B, AB, and 0. The blood types are determined by proteins called antigens. This antigen is found on the surface of the Red Blood Cell (RBC). Basically there are two antigens, A and B. If you have the A antigen on the RBC, then you have type A blood. When B antigen is present, you have type B blood. When both A and B antigens are present, you have type AB blood. When either are present, you have type O blood. When an antigen is resent on the RBC, then the opposite antibody is present in the plasma. For instance, type A blood has anti-type-B antibodies. Type B blood has anti-type-A antibodies. Type AB blood has no antibodies in the plasma, and type O blood has both anti-type-A and anti-type-B antibodies in the plasma. These antibodies are not present at birth but are formed spontaneously during infancy and last throughout life. In addition to the ABO blood group system, there is an Rh blood group system. There are many Rh antigens that can be present on the surface of the RBC. The D antigen is the most common Rh antigen. If the D antigen is present, then that blood is Rh+. If the D antigen is missing, then the blood is Rh-. Blood is transfused to a patient after determining the blood group and matching the characteristics of both. In such case the immune system accepts the foreign object.

the hypothalamus produces corticotropin-releasing hormone (CRH) to stimulate the pituitary gland to make more ACTH. ACTH levels rise in response to stress, emotions, injury, infection, burns, surgery, and decreased blood pressure

The most common time to find out is either when donating blood, or recieving a blood transfusion, or having surgery. If you don't know what type of blood you have, it is difficult to know what kind you would need in the event of a surgery.

Im no doctor but like to share my experience.

My 17 year daughter is diagnosed with ITP. Last year she experienced her first blood transfussion. The adverse effect were severe. She was shiverring and almost lost conciousness. Rushed to ICU to be stabalized. 3 hours later the doctors tried a 2nd attempt and everything was smooths ailing...no side effects.

Just recently, she had to go through another platelet tarnsfussion due to a fever which caused her platelets to reduce tremendously. After about 2 minutes as the platelet entered her system, she started coughing, felt sharp sparks in her face, vommitted, BP dropped to almost zero, in a state of shock..and immediatedly rushed to ICU.

It was a terrible experience as blood transfusion will safe life but theri effects can sometimes be fatal.

My daughter is well now with the help of prednisolone and steroids.

No. An AB neg can receive blood from any blood group with a negative Rh (A neg, B neg, AB neg, O neg).

Blood is separated by centrifugation. That's like when you spin a bucket round your head and it stays put which is centrifugal force. Well, blood is spun round and the heavier particles, red blood cells, go to the outside, middle platelets stay in the middle and the lighter plasma is balanced on the top. Centrifugal force comes from the Latin meaning Centrum "center" and fugere "to flee". It is made when the substance is spun and pushed to the outside; the particles that are heavier have more gravitational pull so they are pulled to the bottom of the container they are in. The machine that blood is separated in is called the centrifuge they are used in laboratories and on an industrial scale for separating solids in suspensions of liquids.

The loss of blood volume and low oxygen levels are the major reasons doctors transfuse blood. Blood volume levels can be replaced without using whole blood or blood plasma. The simplest is saline (salt) solution, which is both inexpensive and compatible with our blood. There are also fluids with special properties, such as Dextran, Haemaccel, and lactated Ringer's solution and Hetastarch (HES). {Such fluids have definite advantages; they are relatively nontoxic and inexpensive, readily available, can be stored at room temperature, require no compatibility testing and are free of the risk of transfusion-transmitted disease} Physicians can also help their patients to form more red cells by giving them iron-containing preparations (into muscles or veins), which can aid the body in making red cells three to four times faster than normal. Your kidneys produce a hormone called erythropoietin (EPO), which stimulates bone marrow to form red cells. Now, synthetic (recombinant) EPO is available. {Doctors may give this to some anemic patients, helping them to form replacement red cells very quickly.***Cooling a patient to lessen his oxygen needs during surgery*Laser "scalpels"*Hypotensive anesthesia*Therapy to improve coagulation*The heart-lung machine*Desmopressin (DDAVP) to shorten bleeding time.***{I've had two 'successful' major surgeries (Hysterectomy and Gall Bladder removal) using a combination of the blood expanders and the surgical procedures highlighted above, without the use of blood or blood products}***

If the recipient has type B blood, they can receive either type B or type O blood. If the donor blood is type B, then the recipient can be either type B or type AB
