Blood Transfusions
A blood transfusion is when blood or blood-based products are transferred from one person to another. This is often done because of major blood loss from something such as an accident or childbirth, but sometimes because of a disease such as anemia or sickle-cell disease.

How long does it take to transfuse packed red blood cells?
It depends on the scenario, PRBC infusers can infuse 1 unit in 5 minutes in trauma settings with acute blood loss while people who have CHF and are at risk volume overload it can take as long as 2-3 or more hours to infuse 1 unit.
Do doctors have to remove blood because of to much volume in the human body?
That idea was held until a few hundred years ago. When a patient was sick with
certain kinds of ailments, doctors would "bleed" the patient, presumably to drain
some of whatever was in him that was making him sick.
Near the end of George Washington's life, he was weak and sinking, and doctors
'bled' him. When it didn't seem to help much, they bled him again, and I believe
they eventually bled him a third and maybe even a fourth time, until the effect
was clear ... he died.
There are procedures in modern medicine where some blood is removed.
Nowadays, it can be blood taken out of a healthy person, and used to replace
blood lost by someone else, either during surgery, or as the result of a violent
injury. Or a person may 'bank' his own blood for use during his own surgery.
But it's never taken out on account of 'too much blood', or to let something
out of a patient that's making him sick.
What do white blood cells look like?
White Blood Cells are roundish in shape, with a rough texture. They are like elastic, they are flexible so they fit through the walls of a capillary, to attack, kill and digest an infection.
What are different examples of a person's blood type?
in the A, B, AB, O. These four blood types also have a positive or negative attached to them.
The bloods are a gang that was created in Los Angeles during the year of 1971. Their color is red, they are rivals to the crips, and in California they are a black gang, but their race may include Latino in other states.
Possibly (Brothers in Blood) this may be an alternate title. curiously I saw this film as a kid at a summer camp conducted by-and there is some humor here-The Brothers of The Sacred Heart!- a religious order. The film was a little risque in one scene the Editor was attempting some amorous relaitons with the leading lady in the back oif a Jaguar(Get in theback of M"Jag! ) then Father Clem the camp director yelleed(stop the Projector!) nuff said. whoever picked out the mo vies either thought it was good religious drama , or knowingly played a prank punning on the very name of the Religious order. it happened.
What are the major functions fo plasma proteins in the blood?
There are numerous kinds of proteins in the blood, thus proteins have many important functions. The major ones are:
- molecule transportation (Ex.: Lipoproteins make it possible for cholesterol to move freely in the aqueous environment of the organism);
- immunity;
- coagulation of blood (clots are made thanks to a reaction chain occurring between many kinds of proteins, the ''coagulation factors'');
- the maintain of oncotic pressure in blood vessels(oncotic pressure is a part of the osmotic pressure between the plasmatic and the lympatic environments).
Other functions exist, though.
Plasma proteins perform various functions. Plasma contains hundreds of proteins each having their specific function. A major protein is Albumin, which is responsible for transport of fatty acids, lipids, drugs etc in the body, it also maintains the osmotic balance with body. Albumin is followed by Immunoglobulins, which are responsible for the immune response. Fibrinogen is responsible for the blood clotting at the time of injury. There is a long list of proteins and an even longer list of their functions.
How much blood does the body have?
The total amount of blood in each person's body is approximately a gallon and a quarter, or ten pints, or 4.7 liters of blood.
Why do Jehovah witnesses not do blood transfusion?
Because in The Bible, it states we shouldn't use or eat blood to sustain the body in any way. Some people abstain from eating blood but then accept a blood transfusion. This is wrong because imagine someone was an alcoholic, so his doctor said to not drink it. Would it be okay if he just simply shot it into his veins? No. Also, some people might say that Jehovah's Witnesses don't accept medical treatment. They say this because they don't accept transfusions. But, actually, they only want the best care for themselves and their families so, they don't want to take any chances. Someone might want to give blood but might have AIDS. The persinal will scan him/her but AIDS can't be found unless it's active so what happens when it's not? They can't find it. so they allow him/her to give blood. When someone has a blood tranfusions with that blood, they can get AIDS! Hopefully that answers your question.

Can A negative blood type receive positive blood type?
An Rh negative recipient may receive Rh positive cellular blood products IF the recipient does not have preexisting Anti-D antibodies present in their plasma, is not a female of child bearing age/capable of becoming pregnant and/or there is an emergent need for blood components (trauma, etc.) and Rh negative products are not available. If Rh positive products are administered to an Rh negative recipient, Rh positive components may continue to be administered until anti-D antibodies are detected on pre-transfusion screening tests. If Rh positive platelets are administered to an Rh negative recipient, Rh Immune Globulin (e.g., RHoGam) may be administered to prevent sensitization in the recipient.
Why do you swing your hand for 10 to 15 second before pricking the tip of your middle finger?
to make the blood circulation move clearly
Why swing hand for 10 seconds before pricking the tip to the middle finger?
when you swing your hand, the inertia will cause the blood to flow to your hand, so there will be enough blood to be tested.
When people need repeated blood transfusion?
Haemophilia(only if bleeding occurs)
leukemia
sickel cell anaemia
beta thalasemia
What is the LPNs role in administration of blood transfusions?
It depends on the state/facility. Most LPNs are not allowed to perform blood transfusions, that is a task that cannot be delegated to ancillary staff, or those that are not registered nurses.
How low does your Hb need to be before they do a blood transfusion?
normal hemoglobin level is between 12-18 g/dL. elderly patient's may be slightly less.
What do type O negative and type AB positive blood have in common?
Type O NEG is the universal red cell donor
AB POS is the universal red cell recipient
Type O is the universal recipient for plasma
AB is the universal donor for plasma
Type O NEG is characterized by the lack of ABO and D antigen on the red cells.
AB POS has every AB/D antigen present on the red cells.
You may find some sort of commonality in there...although it's mostly opposites.
Is it true in some people HIV was unable to be known in blood test up AIDS?
Depends on what type of blood test you take. Regular blood tests do not show AIDS, unless you ask for the facility to look for it. If you have a blood test done for, as an example, being a blood donor, then they will look for AIDS
When you find blood on your panties is there something wrong?
Bleeding after your cycle is over can be caused by a sudden drop in estrogen that occurs just before ovulation. The drop in hormones can trigger withdrawal bleeding. Spotting tends to be more common in longer cycles.
Blood infusion is a misused term for blood transfusion. This is where a person receives blood through an IV.
Is there any blood substitute?
If you meant "is it possible to exchange all the blood with any substitute?" - then "no. that's impossible".
But probably you didn't mean that - would be crazy.
If your looking for some substance to substitute blood during a surgery, i.e. to avoid blood transfusion (as it is always a risky thing)... then yes. High tech hospitals are already doing surgeries without real blood. The problem is the quantity that can be substituted by the specific substances... density, osmolarity... (they check those properties).
So... please check some medical information sites or whatever... I know it exists for sure... those hospitals are really modern (and maybe very few). But don't let anyone tell you there wouldn't be any at all... there has been an international special medical convention in Geneva (Switzerland) about surgeries without blood and blood substitutes. Good luck.

Answer: Some of the Methods
Fluids: Ringer's lactate solution, dextran, hydroxyethyl starch, and others are used to maintain blood volume, preventing hypovolemic shock. Some fluids now being tested can transport oxygen.
Drugs: Genetically engineered proteins can stimulate the production of red blood cells (erythropoietin), blood platelets (interleukin-11), and various white blood cells (GM-CSF, G-CSF). Other medications greatly reduce blood loss during surgery (aprotinin, antifibrinolytics) or help to reduce acute bleeding (desmopressin).
Biological hemostats: Collagen and cellulose woven pads are used to stop bleeding by direct application. Fibrin glues and sealants can plug puncture wounds or cover large areas of bleeding tissue.
Blood salvage: Salvaging machines recover blood that is lost during surgery or trauma. The blood is cleansed and can be returned to the patient in a closed circuit. In extreme cases, liters of blood can be recovered using such a system.
Surgical tools: Some devices cut and seal blood vessels simultaneously. Other devices can seal bleeding on large areas of tissue. Laparoscopic and minimally invasive instruments allow surgeries to be performed without the blood loss associated with large incisions.
Surgical techniques: Thorough operative planning, including consultation with experienced clinicians, helps the surgical team to avoid complications. Prompt action to stop bleeding is essential. Delays greater than 24 hours can greatly increase patient mortality. Dividing large surgeries into several smaller ones decreases total blood loss.
You can find much information on Jehovah's Witnesses official website. Working with Jehovah's Witnesses, many hospitals all over the country have developed a Bloodless Medicine Program and Department. Englewood Hospital snd Medical Center, Englewood, New Jersey is the frontrunner.
What is a blood type table used for?
The blood type table is most often used when determining which types of blood are compatible with others. This is extremely important when in regards to blood transfusions.
