Blood Transfusions

A phlebotomist is an individual trained to draw blood (venipuncture), either for laboratory tests or for blood donations. They are not necessarily (in fact not usually) doctors.

As many as necessary to prevent bleeding associated with thrombocytopenia.

In patients refractory to random donor platelet transfusions, platelet crossmatching may identify units providing better platelet count increases. If crossmatching is not effective, HLA matching of platelets may be necessary.

doctors typically draw blood from veins because veins are more superficial (ie close to the surface of the skin) and therefore more easily accessible. additionally, arteries are under high pressure and there is a risk of major bleeding. lastly, you have less collateral circulation with arteries than veins. what that means is this (let's use your arm as an example): there are many different veins in your forearm that lets blood get from your hand back to your heart, so damaging any one of these veins isn't a big deal. however, there are only two arteries in your forearm that supplies blood to your hand (the radial and ulnar arteries). Arterial blood is sampled from the radial artery because it's bigger and more easily accessible. However, damaging this artery can be catastrophic if the ulnar artery is not well developed, because then your hand is not getting enough blood, and it can become gangrenous and die (this is a vascular emergency). That is why doctors will do an Allen's test (look it up on google... you can even try it on yourself) before doing an arterial stick to make sure you have good blood flow through your ulnar artery that can sustain your hand in case the radial artery is destroyed with the arterial stick. so for these reasons, doctors don't do an arterial blood draw unless they really need one, and the one test that comes to mind where you absolutely need arterial blood is the arterial blood gas test. this test is used when doctors need to know the oxygen saturation and pH of the arterial blood, typically in patients with respiratory failure and sometimes in type 1 diabetics with diabetic ketoacidosis (DKA).

Yes! according to the Halakhah (Jewish law) it's a Mitzva (imperative) to have a blood transfusion when needed, since it's a Mitzva to save one's life.

There are three components of motivation. These three components are activation (beginning a behavior), persistence (continuing the behavior), and intensity (the amount of effort put forth in completing the behavior or reaching a goal).

the average adult has ten pints of blood.

Blood types, as people commonly know, has a classification which is simply based on two things:

* ABO group

* Rhesus factor Now, the ABO group, depends on two antigens; antigen A and antigen B. which lie on the surface of the RBC:

* A person having an A antigen on his RBC cells will show a blood type of A * A person having a B antigen on his RBC cells will show a blood type of B * A person having both A & B antigens on his RBC cells will show a blood type of AB * A person having neither of those antigens will show a blood type of O Second, the rhesus factor, which depends on a single antigen; antigen D, which also lies on the surface of the RBC:

* A person having a D antigen is called an Rh positive, e.g. A, B and D antigens' presence exhibit a blood type of AB+ (universal acceptor)

* A person without the D antigen is called an Rh negative, e.g. Neither A, nor B, nor D antigens' presence exhibit a blood type of O- (universal donor). Both factors combine to form the blood types as we know them today.

The person's body will immediately begin destroying the B blood cells, causing shock and possibly even death. People carry naturally occurring antibodies to A or B antigens if they are not that type, which react strongly with transfused blood to destroy it.

because it is a real universal donor and can donate to every blood group safely.

The Bible says in Acts 15:29 to " Abstain from blood. (Illustration.) If a doctor told a patient who was an alcoholic, drinking a bottle of whiskey every day to ABSTAIN from whiskey or he would soon be dead. Then he said come to my surgery every morning when I start and I will transfuse a bottle of whiskey into your arm. Would that seem right and logical? There is no difference in blood by drinking it and transfusing it except it will affect you quicker. There are many other issues to this matter so the next time the Witness's call on you ask them to give you the booklet. " Blood medicine and the Law of God.

The patient's blood is slowly withdrawn (usually about 5 to 20 mL at a time, depending on the patient's size and the severity of illness). An equal amount of fresh, prewarmed blood or plasma flows into the patient's body. This cycle is repeated until the correct volume of blood has been replaced.

The volume is dependent on the size of the patient, therefore the units of blood required are variable.

yes the hospital do have enough

Well, type A blood can only receive type A blood and those who have type B blood can only use type B blood, and for type AB, you can get type 0 blood meaning you can receive any type of blood in your body has both A and B antigens on red cells. For type A blood, it has only the A has only the A antigen on red cells and for type B blood, it has only the B antigen on red cells.

All of them.

Hospital induced volume overload is the over-infusion of fluids by a hospital. Overload can cause congestive heart failure, pulmonary edema, or generalized edema. (Edema is the collection of fluid outside of cells or veins.) Overload can be mild or life threatening. It is generally a correctable problem.

Human blood is only good for about 4 hours after it is no longer refrigerated, so if the transfusion takes longer than that, the remainder must be discarded and a new unit ordered. Typically transfusions are given pretty slowly so the body can adjust. (about 4 ml per minute or less in an adult)

can

Red blood cells (RBC) have different surface protein's (antigens) such as a person with blood group B will have B antigens on their RBC surface. someone with blood group B will the have antibodies in their plasma that attack A antigens. this reaction between the antibodies and antigen is that dangerous if only 10ml of the wrong blood enters the body, it is fatal.

Here are some combinations of blood types that can be donated to different blood types.

AB+; ALL BLOOD TYPES.

AB-; ALL NEGATIVE GROUPS

B+; B+, B-, O- AND O+

B-; B- AND O-

A+; A+, O+, A- AND O-

O+; O+ AND O-

O-; O- ONLY

so those with blood group O- are most at risk if anything is to go wrong, hospitals run vigorous training session to insure that mistakes never happen, if something is to go wrong, the person that was responsible would be likely to lose their job unless proven that it was not their fault.

Hemophilia commonly describes a condition where the patient is deficient in a clotting factor. Hemophilia A is associated with deficiencies in Factor VIII, while Hemophilia B is associated with Factor IX deficiencies. Decreased levels and/or inhibition of factor activity may lead to increased risk of bleeding. Red cell transfusions may be needed to treat acute or chronic anemia associated with an increased bleeding tendency.

Specific clotting factor concentrates are used in modern transfusion medicine to treat such conditions, while fresh frozen plasma and/or cryoprecipitate are used when multi-factor deficiencies are present (i.e, liver disease, hypo/dysfribrinogenemia) and specific factor concentrates are not available.

one answer is to extract the flavor of a substance by placing it in a hot liquid.

For example tea bag put in hot water to make tea. The flavor escapes into the water.

No.

If they are saved (Catholic or Baptist, Methodist, Lutheran) they are receiving comfort from the fact that Christ died for them, and thanks be to Him, they are going to heaven to live with Him eternally. He died for everyone, including the dying people as well as those who reject Him, and if that dying person accepted Him, that person can die in peace.

There are a number of things that a snake can and will eat. Typically snakes eat small animals like mice.
