Breathing reserve

The human body is an amazing creation of nature. With all their diversity, people have one thing in common - they breathe. And how effectively this process is carried out is very important for the body as a whole. With the exception of rare cases (for example, with pathological changes in blood properties), the respiratory rate of a person in a calm state (lying on his back) is 9-17 inhalations and exhalations per minute. This breathing is called short breathing (in other words, systolic breathing, respiratory rate = 14-20 min-1 at rest). Imagine that you



What is respiratory reserve and its importance for health

**Respiratory reserve** is the difference between the maximum breathing volume (maximum ventilation) and the minute breathing volume at rest. Maximum ventilation, or maximum respiratory rate, is determined by the tidal volumes of air that a person can inhale or exhale in a certain period of time, for example, per minute. Minute respiration volume is measured as the amount of air that a person exhales or inhales in one minute. If the difference between these two indicators is small, it may indicate certain diseases or disorders of the respiratory system, such as bronchial asthma, emphysema, chronic obstructive pulmonary disease (COPD) or smoking. However, if the difference between maximum ventilation and minute volume of respiration is high, this indicates the body's ability to quickly restore its oxygen supply during physical activity, which is an important condition for health and performance.



Respiratory reserve is a key variable that reflects a person's ability to breathe without compromising health. This is the most important indicator of homeostasis - the state of the body, reflecting adaptive reactions and being disrupted by the external environment.
