The word “infusion”, when used in ICU, means giving fluids directly into the bloodstream. Machines called infusion pumps are used to do this. Infusions often contain liquid medicines.
First, a small plastic tube is inserted into a patient's vein. This tube is often called a ‘line‘. The veins used for infusions are usually in the neck, the groin or the arms. The line is connected to the infusion pump. An infusion bag with the liquid for the body is attached to the pump.
Many kinds of medicines can be given via an infusion pump. Examples are antibiotics, strong heart medicines such as adrenaline and blood pressure medicines.
