Expiratory Reserve Volume

Expiratory reserve volume is the volume of air that a person can exhale after maximal exhalation. It is about 1.5-2 liters and is one of the indicators of the respiratory system.

Expiratory reserve volume is important for assessing the state of the respiratory system and its functioning. If you have lung disease or other breathing problems, this volume may be reduced, which can lead to a lack of oxygen in the body and poor health.

To measure the expiratory reserve volume, a special device is used - a spirometer. This is a device that measures the volume of air passing through the lungs when breathing. During the measurement, the person must exhale as much as possible, after which he is asked to slowly inhale air into the spirometer. The measurement results allow you to assess the condition of the respiratory system and identify possible problems.

In addition, expiratory reserve volume plays an important role in sports. Many sports such as running, swimming, gymnastics and others require deep breathing and maximum use of the lungs. Therefore, it is important to know your reserve volume and train it to achieve better results.

Thus, expiratory reserve volume is an important indicator of the health of the respiratory system, and its measurement can identify possible problems and improve health.

Expiratory reserve volume

Expiratory reserve volume is the volume of gas that can be exhaled from the lungs after a quiet inhalation of air in the first two seconds of a quickly exhaled breath. The reserve depends on the air temperature and the ratio of O2 and CO2 at the entrance to the lungs. The higher the air temperature, the more you can exhale,
