Ventilation, Breathing

Ventilation of the Lungs, Breathing (Ventilation) is an important process that ensures the flow of air into the respiratory tract and its removal from them. This process is necessary to maintain the normal functioning of the lungs and the entire body as a whole. In this article we will look at how ventilation occurs and what consequences may arise if it is disrupted.

The process of ventilation begins with inhaling air through the nose or mouth. The air passes through the trachea and bronchi, ending up in the final sections of the respiratory tract - the alveoli. Alveoli are small bubbles surrounded by a network of capillaries through which gas exchange occurs between blood and air. As a result of this process, the blood is enriched with oxygen, and carbon dioxide is removed from the body.

One important aspect of ventilation is dead space ventilation. This is the space in the respiratory tract in which air exchange occurs, but there is no gas exchange between blood and air. Therefore, the air passing through the dead respiratory space does not participate in the gas exchange process and does not contribute to the enrichment of the blood with oxygen. A tracheostomy is a surgical procedure that creates an artificial opening in the windpipe to make breathing easier. Thus, tracheostomy can help reduce dead air space and improve ventilation.

Violation of the ventilation/perfusion process can lead to serious consequences for the body. Ventilation/perfusion mismatch of alveoli that are poorly washed by blood can lead to ineffective gas exchange and the development of anoxia - oxygen starvation of tissues. Perfusion of poorly ventilated alveoli (shunt) can also lead to anoxia and cyanosis - a blue-violet discoloration of the skin and mucous membranes due to lack of oxygen in the blood.

In conclusion, ventilation is an important process that ensures the normal functioning of the body. Impaired ventilation/perfusion can lead to serious health consequences. Therefore, it is important to monitor your lung health and seek medical help if you experience breathing problems.



Ventilation is the process of air entering and removing from the respiratory tract. It plays an important role in gas exchange at the level of the alveoli of the lungs, which is necessary to maintain the vital functions of the body.

The respiratory system consists of the airways, lungs and breathing muscles. The respiratory tract includes the nasal cavity, oral cavity, larynx, trachea, bronchi and bronchioles. The lungs consist of many small bubbles - alveoli, which are surrounded by a network of capillaries.

The air passing through the respiratory tract does not take part in the gas exchange process, therefore this area is called dead space ventilation. In the alveoli of the lungs, effective gas exchange occurs between the blood flowing through the capillaries and the air ventilating the alveoli (perfusion).

However, disruption of the ventilation/perfusion process (ventilation of poorly washed blood or perfusion of poorly ventilated alveoli) is one of the important reasons for the development of anoxia and cyanosis. Anoxia is the lack of oxygen in the tissues, and cyanosis is the coloring of the skin and mucous membranes blue, caused by insufficient oxygen supply to the blood.

To maintain normal ventilation of the lungs, it is necessary to ensure free breathing and proper functioning of the respiratory muscles. However, in some cases, pulmonary ventilation may be impaired, for example, with diseases of the respiratory system, injuries, operations, intoxication and other conditions.

Tracheostomy, a surgical procedure that creates an opening in the trachea to make breathing easier, may be used to treat severe ventilation problems. A tracheostomy can be temporary or permanent and can be used as an alternative to intubation - inserting a tube into the airway through the mouth or nose.

In conclusion, ventilation is an important process that allows oxygen to enter the body and carbon dioxide to be removed. Poor ventilation can lead to serious health consequences, so it is important to seek medical help at the first sign of breathing problems.



In the process of human life, a constant supply of oxygen and removal of carbon dioxide from the body is necessary. This process occurs through breathing, that is, air circulation through the lungs. The need for timely supply of oxygen to the lung tissue and the need to remove carbon dioxide is due to the presence of special organs that perform these functions - the lungs.

Ventilation of the lungs should be understood as the process of moving air during inhalation and exhalation. But what kind of air should get into the lungs? The air inside the lungs is usually called outside air or atmospheric air. This definition applies to both inhalation and exhalation. Outside air is a mixture of gases contained in the atmosphere. Gases such as oxygen and carbon dioxide are present in certain proportions during respiration. Changing this ratio by regulating inhalation and exhalation allows the body
