this is he total volume of air you can forcefully expire until you can not blow any air out. So you have to use the maximum force and as long a you can to blow out all the air from your lungs. In health person the volume will depend on height, weight, age and gender. in a twin the boy will blow out more than a girl. When you are 18, you will blow out air more than your father would,
