Perfusion

1. The passage of fluid through tissue, in particular, the passage of blood through lung tissue to enrich it with air oxygen contained in the alveoli (it gets there thanks to the constantly ongoing process of ventilation of the lungs) and remove carbon dioxide from it. If the process of ventilation of the lungs is disrupted for any reason, then venous blood with insufficient oxygen content in it returns to the general bloodstream. If the perfusion process is disrupted, then incomplete gas exchange occurs in the patient’s body.

2. The deliberate introduction of fluid into a tissue (usually by injecting it into the blood vessels supplying that tissue).

Perfusion: What is it and why is it important?

Perfusion is the process of fluid passing through tissue, including blood passing through lung tissue to enrich it with oxygen and remove carbon dioxide. This process is the primary mechanism for delivering oxygen and nutrients to the body's cells and removing waste and carbon dioxide from the body.

If the process of ventilation of the lungs is disrupted for any reason, then venous blood with insufficient oxygen content in it returns to the general bloodstream. This results in insufficient oxygen supply to tissues, which can lead to serious consequences including cardiac arrest and death.

In addition, if the perfusion process is disrupted, then incomplete gas exchange occurs in the patient’s body. This can lead to the development of acute or chronic diseases such as myocardial infarction, stroke, acute renal failure and others.

The deliberate introduction of fluid into a tissue (usually by injecting it into the blood vessels supplying that tissue) is also called perfusion. This method is used to deliver drugs and other substances directly to the desired tissues of the body, providing a quick and effective treatment effect.

Perfusion is also an important element in medical diagnostics, especially in the field of brain imaging. The perfusion tomography method allows you to evaluate blood flow in the brain, identify disturbances in this process, and identify areas of the brain that do not receive enough oxygen and nutrients.

Overall, perfusion is an important process for maintaining body health and treating various diseases. Its normal functioning ensures proper gas exchange and the supply of oxygen and nutrients to tissues, as well as the removal of waste and carbon dioxide.
