How long does a transfusion take? Type of transfusion Timing Red cells For many people, this takes 90— minutes per unit. But for a severe hemorrhage, it may be possible and necessary to give each unit in 5—10 minutes.
Platelets This transfusion usually takes 30—60 minutes per unit. Fresh frozen plasma The rate is usually 10—20 milliliters per hour. How long does a blood transfusion take to work? Who needs a blood transfusion? Types of transfusion. What to expect during the procedure.

Is blood actually blue? Health-care facilities must have an approved process for ongoing inspection and validation for all infusion devices. Infusion devices have been known to cause mechanical hemolysis; 18 therefore, prior to implementing the use of an infusion device, confirmation that it has been approved for use in transfusing blood components should be obtained from the manufacturer.
See Chapter 10 of this Guide for more information about the causes of mechanical hemolysis. Infusion devices may be used to transfuse blood components e. The use of infusion devices must always adhere to the health-care facility policy. A pressure infusion device may be used for rapid administration of blood components. The pressure applied to the blood component should not exceed mm Hg as this may result in hemolysis or bag breakage.
A blood warmer device may be used to prevent hypothermia during rapid administration of cold blood components, such as in the operating room or trauma setting.
A blood warmer device may be used in routine transfusion for a patient with cold agglutinin disease; however there is limited evidence for the efficacy of this strategy and warming the patient is more likely to be feasible and just as likely to be beneficial.
When a blood warmer is used, the temperature upon initiation and the unique identifier of the device e. Pre-transfusion patient assessment and a measurement of baseline vital signs must be documented within 30 minutes prior to transfusion. Identify any potential risks of a transfusion reaction or any pre-existing symptoms that could later to be mistaken for a transfusion reaction e.
If the patient is able to participate, education should be provided so the patient understands the importance of immediately reporting any new onset symptoms during or after transfusion. Any pre-medications required should be prepared and administered as ordered e. Blood components and PPP must be stored in monitored blood storage and transported in a validated system. Storage and transport systems are validated and monitored by the transfusion service.
A blood component or PPP should only be obtained from storage when all preparation for administration is complete. Prior to obtaining a blood component or PPP, confirm that a transfusion order exists and informed consent is documented.
Follow health-care facility procedures when obtaining a blood component or PPP from the transfusion service or satellite blood refrigerator. It is imperative that positive patient identification is confirmed again at this time and the right product is obtained for the right patient. If the retrieved blood component or PPP is no longer required, it should be returned immediately to the transfusion service to maintain safe storage conditions and prevent waste. The pre-transfusion safety check includes checking the blood component or PPP and verifying positive patient identification on the product to the patient.
All identifying information linking the patient to the blood component or PPP must be matched. Always follow facility-specific policies for confirming patient identification and the blood component or PPP. Depending on the blood component or PPP to be administered, there will be additional considerations. See Table 3 for a summary of administration requirements. As mentioned previously, misidentification can occur at several points during the transfusion process and it is imperative that positive patient identification is maintained through the entire process.
The safety check immediately prior to administration of a blood component or PPP is the last opportunity to prevent an identification error from reaching the patient.
The following list summarizes the general steps included in preparing for and initiating a blood transfusion. Confirm consent for transfusion. Provide information to the patient regarding the planned transfusion e. Confirm pre-transfusion testing or collect pre-transfusion sample if applicable. Assemble required equipment. Complete a patient assessment and obtain baseline vital signs within 30 minutes pre-transfusion.
Administer pre-medication s if required. Obtain the blood component or PPP from storage or the transfusion medicine laboratory. Complete pre-transfusion checks.
Refer to facility-specific policies and procedures. Document the pre-transfusion checks, including date and time and the identity of the persons completing the checks.
Prepare to initiate the blood component or PPP:. One unit usually takes 1. Maximum infusion time is 4 hours. Platelets are transfused through platelet filters at a rate which allows a pool of random donor platelets or a single donor platelet to be transfused within 30 to 60 minutes. FFP is usually transfused through a standard blood filter at a rate of 30 to 60 minutes per bag.
At this rate, a pool of 10 bags can be infused in approximately 30 minutes. Transfusion Delays If the start of a transfusion is delayed after a unit of Red Blood Cells has been issued, the unit can be returned to inventory if it has not remained at room temperature for more than 30 minutes.
The Red Blood Cell unit's temperature will usually not exceed 10o C for at least the first 30 minutes at room temperature. If a unit remains at room temperature for longer periods of time, glucose and ATP might become depleted and any contaminating bacteria might begin to proliferate. Home Transfusion Blood Infusion. Blood Infusion. Blood components must be filtered during transfusion to remove clots and small clumps of platelets and white blood cells that form during collection and storage.
Standard blood infusion sets contain - micron filters. Smaller component sets with in-line filters for plasma, platelets, and red cell aliquots are also available. The manufacturer provides instructions for priming and use on the infusion set package. Blood sets should not be piggy-backed into other lines if this can be avoided.
Injuries or surgeries that cause a high amount of blood loss can become emergencies. In cases of chronic medical conditions, your doctor will order a blood test called a complete blood count CBC to determine if you need a blood transfusion. It takes just a few minutes for blood to be drawn for this test. Results are available anywhere from a few hours to a few days later. If your situation is an emergency, a doctor will act before waiting for the results of the blood test.
Once your doctor has determined that you need a blood transfusion, a medical professional will draw another blood sample. The sample will be sent to a lab for testing known as blood typing and crossing. This testing can be done in just a few minutes.
Knowing your blood type is important. It ensures the type of blood your doctor gives you is a match. Your identity will be checked to ensure you are given the correct blood. They will administer the blood through this line. A nurse will remain with you for at least the first 15 minutes of the transfusion. This is because most reactions with blood transfusions, if they happen, occur immediately.
Examples of transfusion reactions include:. Over the course of the transfusion, your nurse or doctor will check your vital signs frequently.
