Blood transfusions are done to replace blood lost during surgery or due to a serious injury. A transfusion also may be done if your body can't make blood properly because of an illness. During a blood transfusion, a small needle is used to insert an IV line into one of your blood vessels. Through this line, you receive healthy blood. The procedure usually takes 1 to 4 hours, depending on how much blood you need. Blood transfusions are very common. Each year, almost 5 million Americans need a blood transfusion.
It also helps to improve the oxygen saturation in blood. It can be stored at 1.0 Â°C-6.0 Â°C for 35â45 days. Platelet transfusion, is transfused to those who suffer from low platelet count. This can be stored at room temperature for 5â7 days. Plasma transfusion is indicated to patients with liver failure, severe infections or serious burns. Fresh frozen plasma can be stored at a very low temperature of -25 Â°C for up to 12 months.
