Légzéskapacitás

Légzéskapacitás, often translated as lung capacity or respiratory capacity, refers to the total volume of air that the lungs can hold. It is a measure of the lungs' ability to inhale and exhale air. This capacity is influenced by several factors, including age, sex, height, and overall health, particularly the presence of respiratory conditions.

There are several components that make up lung capacity. Vital capacity is the maximum amount of air a person can exhale after a maximal inhalation. It represents the usable volume of air in the lungs. Total lung capacity is the total volume of air in the lungs after a maximal inhalation, including residual volume, which is the air remaining in the lungs even after a maximal exhalation. Functional residual capacity is the volume of air remaining in the lungs after a normal exhalation.

Measuring légzéskapacitás is typically done using spirometry, a non-invasive test that measures lung function. Doctors use these measurements to assess lung health, diagnose respiratory diseases such as asthma or COPD, and monitor the progression of these conditions. Changes in légzéskapacitás can indicate underlying health issues, and maintaining good respiratory health through exercise and avoiding irritants is important for preserving lung function.
