Vital capacity (VC) refers to the total amount of gas that can be exhaled at a time when you try to breathe in. Adult men’s vital capacity is about 3500-4000 milliliters, and women are about 2500-3000 milliliters. The better the health is, the greater the vital capacity is.
Spirometer is a portable, handheld device for measuring your ability to exhalate air from the lungs, and can provide a correct data to reflect the ventilation of the trachea.
