Answer:
if you doctor suspect that you have COPD , they will calculate your fev1/fvc ratio . this represent the percentage of your lung capacity that you can explain in one second. the higher your percentage , the larger your lung capacity and the healthier your lungs
The ratio [tex]\frac{FEV1}{FVC}[/tex] indicates the diameter of an airway. The greater the value, the more quickly air can pass through the airway.
The volume of air in the lungs at different stages of the respiratory cycle is referred to as lung volumes and lung capacities. An adult human male's entire lung capacity is around 6 liters of air.
The ratio [tex]\frac{FEV1}{FVC}[/tex] indicates the diameter of an airway. The greater the value, the more quickly air can pass through the airway. As a result, the lower the resistance, the broader the airway becomes.
Hence the lower the resistance, the broader the airway becomes.
