Residual Air

Residual air is a term used in classical medicine to refer to a physical phenomenon that is associated with the presence of air in a person's blood vessels and tissues between inhalation and exhalation. This air is not considered full breathing, but is of great importance for the functioning of the body, as it ensures gas exchange and maintains oxygen balance in cells and tissues.

The air contained in the vessels is called residual air. Its presence means that blood must pass through it when breathing, causing resistance to blood flow. Residual air is an important component of the functioning of the cardiovascular system, as it ensures the exchange of oxygen and carbon dioxide between the blood and air. In this case, residual air can cause shortness of breath and difficulty breathing, especially in people with diseases of the respiratory system.

However, according to modern concepts, there is no residual air; such air is called gas chromium and its amount is directly proportional to the hemic oxygen threshold. There are other theories of the occurrence of residual air, which explain its presence by various physiological abnormalities, such as bronchiectasis, lung collapse and
