The process begins with the insertion of an IV catheter, typically into a vein in the arm, though other sites may be used depending on the patient's condition and the type of infusion required.

Once the catheter is in place, a sterile solution containing the medication or fluid is connected to the IV line. The solution is administered at a controlled rate, which can be adjusted based on the patient's response and the specific treatment protocol. Infusion therapy can be continuous, where the medication is delivered steadily over a period, or intermittent, where doses are given at specific intervals.

Healthcare professionals closely monitor patients receiving infusion therapy to ensure the treatment's effectiveness and address any potential side effects. The process requires careful preparation and adherence to sterile procedures to minimize the risk of infection and ensure the treatment's success.

How Does Transfusion Work?

Blood transfusion is a complex process that involves matching the donor's blood type with the recipient's to ensure compatibility. The procedure begins with the collection of blood from a suitable donor. This blood is then tested for compatibility and screened for infectious diseases to ensure its safety for transfusion.

Once compatibility is confirmed, the blood or blood components are prepared for transfusion. The patient typically receives the transfusion through an IV line inserted into a vein. The rate of transfusion is carefully controlled, and the patient is monitored throughout the process for any adverse reactions such as fever, chills, or allergic responses.

Transfusions can involve whole blood or specific components like red blood cells, platelets, or plasma, depending on the patient's medical needs. Each component serves a different purpose, such as increasing the oxygen-carrying capacity of the blood or aiding in clot formation.
