How does an air embolism occur during a blood transfusion?
GaleEncyofMedicine
Very rarely, an air embolism is created when air is introduced into a patient's veins through the tubing used for intravenous infusion. The danger of embolism is greatest when infusion is begun or ended.

What are the risks associated with receiving a blood transfusion?
Sometimes problems occur with a blood transfusion, but that is supposed to be rare. Some people can have an allergic reaction to the transfusion.
What is Embolism?
Embolization. Material injected into the vessel blocks blood flow which helps control blood loss during or reduces the size of inoperable growths. A serious side effect, stroke, can occur if a major blood vessel becomes blocked.
When does cerebral embolism occur?
Cerebral embolism occurs when a blood clot from elsewhere in the circulatory system breaks free. If it becomes lodged in an artery supplying the brain, either in the brain or in the neck, it can cause a stroke.
What blood clot forms after a fracture?
A clot that has dislodged into the vascular system is called an embolism. When you fracture a long bone you run the risk of fat from the bone marrow becoming dislodged into your blood vessels and forming a fat embolism.
What is thrombo embolism?
A thrombus is a blood clot. It is attached to the wall of the blood vessel. If it dislodges to flow thru the blood stream then the blood clot is called an embolus. Oftentimes the terms 'blood clot and thrombus' are used interchangeably clinically. However, it is important to note that a 'clot' is the result of the coagulation cascade (e.g. such that it can occur in a vial), while a thrombus refers to BOTH the coagulation cascade occurring AND the aggregation of platelets on the side of a vessel.
What conditions are caused by blood clots?
A blood clot that blocks an artery to the brain can cause a stroke. If the clot blocks blood flow to the lungs pulmonary embolism can occur. A blood clot that blocks a coronary artery can cause a heart attack.
Why does a transfusion reaction not occur the first time a rh positive patient is exposed to rh negative blood?
the transfusion reaction doesn't occur the first time an Rh+ patient is exposed to Rh- blood because the Rh+ patients body hasn't created the antibodies needed to attack the Rh- blood that it comes in contact with. the second time the Rh+ patients body comes in contact with Rh- blood, it will have the antibodies necessary to fight against Rh- blood.
Why can't blood be donated for a year after a transfusion?
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 can a person with rh- blood not receive rh plus blood?
The person with Rh- blood will begin to make antibodies against Rh+ upon exposure. This may not occur with the first transfusion - but it is still not recommended to give an Rh- person Rh+ blood.
My mother-in-law is 89 and needs a blood transfusion. Her blood count is a 6.7. She is on hospice and has a dnr. Is this the point where she will start having problems?
This is a point where continual decline will occur. But, it is not necessarily where problems will now begin.
What happens if a person is given the wrong blood during transfusion?
It's most likely that the person would die because their body would reject the blood, and it would be just as effective as filling the person with water.
Can there be multiple blood clots in pulmonary embolism?
Yes, a person can have multiple pulmonary embolisms. They can have many small ones, or just one and can occur in just one lung, or both at the same time.
