Intravenous therapy consists of a long, progressive injection to the vein. A catheter, a type of flexible tube, is inserted into a peripheral vein, or sometimes into a central vein to allow for a higher volume of diffusion. Fluids administered can be blood, in blood transfusions particularly used in cases of severe anemia (decrease in blood hemoglobin volume); or a solution of molecule compounds aimed at stimulating blood pressure when it falls too low to compensate for blood loss following an accident, for example; or even medication. This last type of intravenous therapy is employed when oral administration is not possible, due to the patient being incapable of taking medication orally, or when a faster, more effective treatment is required, such as for certain potentially serious infections. The possible complications consist primarily of venal inflammation and blood infection.
