Vital Capacity is the maximum amount of air a person can exhale after taking the deepest breath possible. It is an important measure of lung function and overall respiratory health. Vital Capacity is typically assessed using a device called a spirometer, which helps to determine how well the lungs are working. This measurement is crucial for diagnosing and monitoring conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other respiratory disorders. Vital Capacity can be influenced by factors like age, gender, body size, and physical fitness, making it a valuable indicator of an individual's lung capacity and health status.
