Lung Volume Residual Volume

Residual volume is the amount of air remaining in the lungs after maximum exhalation. This volume is usually about 1-1.5 liters.

The residual volume is necessary to maintain the structure of the lungs and prevent lung collapse. It fills the bronchi, bronchioles and alveoli even after full exhalation.

An increase in residual volume is observed with the development of pulmonary emphysema, a chronic disease in which stretching and destruction of the pulmonary alveoli occurs. This leads to disruption of bronchial obstruction and accumulation of air in the lungs. Therefore, with emphysema, the residual volume can increase 2-3 times compared to the norm.

Thus, the residual volume of the lungs is an important indicator of their functional state. Its increase may indicate the development of pathological processes in the respiratory system.

Residual volume (RV) is a parameter that characterizes the volume of air remaining in the lungs after full exhalation. It is one of the important indicators of lung function and is used to diagnose various diseases.

RV is measured using spirometry, which measures the volume of air moving through the lungs with each inhalation and exhalation. This measures the volume of air leaving the lungs at one time, as well as the time required for complete exhalation.

Residual lung volume can vary depending on many factors such as age, gender, weight and level of physical activity. In healthy people, RV is about 1-2 liters. However, in some lung diseases, such as emphysema, RV may increase. This occurs because more air remains in the lungs after exhaling than usual.

Measuring residual lung volume can be useful for diagnosing various lung diseases, such as chronic obstructive pulmonary disease (COPD), bronchiectasis, pneumonia, etc. This parameter can also be used to evaluate the effectiveness of treatment and monitor lung condition.

In conclusion, residual lung volume is an important parameter that helps evaluate lung function and diagnose various diseases. To measure it, the spirometry method is used, which is simple and accessible to most patients.

Residual volume (RV), also known as lung reserve volume or expelled residual air, is the amount of air that remains in the lungs after exhalation and the exhalation of the body's entire oxygen reserve.

The RV value is one of the indicators of external respiration function and is used in pulmonology to assess the condition of the lungs and diagnose diseases of the respiratory system.

Residual lung volume: - Measured in milliliters. - Determined using the external respiration function (spirometry). - Changes in residual lung volume may be associated with a variety of lung diseases, including emphysema (widening of the space between the alveoli of the lungs as a result of aging lung tissue, damage to the alveolar wall, or insufficient ventilation of the lungs), bronchitis, bronchial asthma, congestive heart failure, and some abnormalities of the heart or respiratory system, for example, with a ventricular septal defect.
