Definition of perfusion - What it is, Meaning and Concept

Knowing the etymological origin of the word perfusion leads us to decide that it derives from Latin.Specifically we can determine that it is the result of the sum of several Latin components: • The prefix “per-”, which is equivalent to “by complete.”• The verb“ fundere ”, which is synonymous with“ melt or spill.”• The suffix“-sion ”, which is used to indicate“ action and effect.”

Perfusion is a term linked to the verb perfuse , whose action is to make a liquid enter slowly but steadily into the body.The substance to be introduced can be serum , blood or an antibiotic , to name a few possibilities, which is injected into the veins.

It is necessary to establish that in order for perfusion to be carried out, it is necessary to have a series of elements such as a catheter, which is the one that inserts into the vein to get the liquid to penetrate the body.

In addition to all of the above, we would have to establish that, as a general rule, any physician bets on perfusion when the patient cannot take a specific medication by himself or when a quick solution to a powerful problem is necessary.which can be very serious or even fatal if it is not stopped without delay.

However, we cannot forget that, sometimes, when you decide to carry out an infusion, obstacles are encountered.In particular, several complications can arise, the most frequent being, blood infection or inflammation of the veins.

For medicine , therefore, perfusion is the supply of certain substances to a system, an apparatus, a tissue or an organ.It may be the blood circulation (naturally or artificially promoted) or intravenous drug provision.

Based on this main idea, various medical concepts have been developed.The myocardial perfusion , for example, is the clinical analysis that is carried out from the injection of radiopharmaceuticals in the patient.Part of these substances lodge in the myocardium and adhere to the mitochondria, which allows us to study how blood supply develops and detect possible coronary disorders.

The idea of ​​ ventilation-perfusion relationship , on the other hand, is used to express the link between pulmonary ventilation (V) and circulatory flow (Q) of the lungs.The relationship considered as Normal is between 0.8 and 1 V/Q per minute.An embolism can increase this relationship, while the lack of oxygen generates the opposite effect.

The blood flow that reaches the brain , finally, is called cerebral perfusion .The pressure produced by this infusion must be maintained within a specific range, otherwise, the person may suffer from various disorders (such as an ischemia).

It should also not be overlooked that there is what has been called renal perfusion.out to find out how much blood is in the body and how it is distributed to the kidneys.Only so you can know if the person in question suffers from any disease.
