Knowing the etymological origin of the word perfusion leads us to rule that it derives from Latin. Specifically, we can determine what is the result of the sum of several Latin components:
• The prefix "per-", which is equivalent to "completely".
• The verb “fundere”, which is synonymous with “melt or spill”.
• The suffix “-sion”, which is used to indicate “action and effect”.
Perfusion It is a term linked to the verb infuse , whose action is to make a liquid enter slowly but steadily in the body. The substance to be introduced can be serum , blood or a antibiotic , to name a few possibilities, which is injected into the veins.
It must be established 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 doctor bets on perfusion when the patient cannot take a specific medication by himself or when a rapid 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 perform an infusion, obstacles are encountered. In particular, several complications may arise, the most frequent being blood infection or inflammation of the veins.
For the medicine therefore the perfusion is the supply of certain substances to a system, an apparatus, a tissue or an organ. It may be blood circulation (naturally or artificially promoted) or the intravenous supply of drugs.
From 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. Some of these substances lodge in the myocardium and adhere to the mitochondria, which allows us to study how blood irrigation develops and detect possible coronary disorders.
The idea of ventilation-perfusion ratio On the other hand, it is used to express the link between pulmonary ventilation (V) and the circulatory flow (Q) of the lungs. The ratio considered 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, it is called cerebral perfusion . The pressure produced by this infusion must be maintained within a specific range, otherwise the person You can suffer from various disorders (such as ischemia).
Nor should we overlook that there is what has been called renal perfusion. This is done to find out how much blood is in the body and how it is distributed to the kidneys. Only then can you know if the person in question suffers from any disease.
