Detailed explanation-1: -Vital capacity (VC), the volume of exhaled air after maximal inspiration, normally is 60 to 70 mL/kg and in normal persons is determined primarily by the size of the thorax and lungs.
Detailed explanation-2: -It is the total amount of air exhaled after maximal inhalation. The value is about 4800mL and it varies according to age and body size.
Detailed explanation-3: -Some examples of spirometry measurements are: Forced vital capacity: the maximum amount of air you can forcibly exhale from your lungs after fully inhaling. It is about 80 percent of total capacity, or 4.8 liters, because some air remains in your lungs after you exhale.
Detailed explanation-4: -The volume of air remaining in the lungs even after a forcible expiration is called Residual Volume. This is about 1100 ml to 1200 ml in a normal adult.
