What are the definition of IV fluids administration?

Intravenous administration involves directly delivering the drug into the veins., ensuring that the entire dose enters the patient's bloodstream. Intravenous administration leads to immediate therapeutic effect yet this effect is irreversible.

Intravenous administration refers to supplying medication directly into the blood stream. A hollow tube attached to a hollow needle (cannula) is inserted into a patients vein. The tube and needle are secured to the skin with adhesive tape so that it doesn't come out when a patient moves. The other end of the tube is usually attached to an IV bag that contains medication and a carrier fluid, such as a saline (salt) solution. In between there would be a manual roller clamp that can be used to control or limit the infusion (rate of flow) of the medication by pinching the tube as well as a slide clamp to shut it off completely without having to disturb the roller clamp setting. The tube can also go through a computerized machine to accomplish the same and keep track of the amount of fluid used.
