What is stage 1 emphysema?

ANSWER

Emphysema stages are a measure of how well you can breathe. One widely used guideline is called the Global Initiative for Chronic Obstructive Lung Disease (GOLD). It says that stage 1 emphysema is when the amount of air you can breathe out in 1 second is 80% or more of the average for someone of your age, sex, and height.
