Perfusion is based on allowing a liquid to enter the body in a sustained and slow manner.
Knowing the etymological origin of the word perfusion leads us to rule 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 “completely”.
• The verb fundere , which is synonymous with “melt or pour.”
• The suffix -sion , which is used to indicate “action and effect.”
Perfusion is a term linked to the verb perfuse , whose action consists of causing a liquid to enter the body slowly but steadily. The substance to be introduced can be serum , blood or an antibiotic , to name a few possibilities, which is injected into the veins.
Development of perfusion
It must be established that in order for the perfusion to be carried out, it is necessary to have a series of elements such as a catheter, which is inserted into the vein to ensure that the liquid penetrates the body.
In addition to all of the above, we would have to establish that, as a general rule, any doctor opts for perfusion when the patient cannot take a specific medication on his or her own or when a quick solution to a far-reaching problem that can be very serious is necessary. serious or even fatal if not stopped without delay.
However, we cannot forget that, sometimes, when you decide to carry out a perfusion, you encounter obstacles. Specifically, several complications can arise, the most common being blood infection or inflammation of the veins.
Blood perfusion is necessary in certain cases.
The notion of medicine
For medicine , therefore, perfusion is the delivery of certain substances to a system, an apparatus, a tissue or an organ. This may involve blood circulation (natural or artificially promoted) or intravenous delivery of drugs.
From this main idea, various medical concepts have been developed. Myocardial perfusion , for example, is the clinical analysis that is carried out from the injection of radiopharmaceuticals into the patient. Part of these substances stay in the myocardium and adhere to the mitochondria, which makes it possible to study how the blood supply develops and detect possible coronary disorders.
Different types of perfusion
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 normal is between 0.8 and 1 V/Q per minute. An embolism can cause this ratio to increase, while a lack of oxygen generates the opposite effect.
The blood flow that reaches the brain , finally, is called cerebral perfusion . The pressure produced by this perfusion has to be maintained within a specific range, otherwise the person may suffer various disorders (such as ischemia).
Nor should we overlook the fact that there is what has been called renal perfusion. This is carried out to find out how much blood there is in the body and how it is distributed to the kidneys. Only in this way can you know if the person in question suffers from an illness.
