The second key spirometry measurement is FEV1. This is the amount of air you can force out of your lungs in 1 second. It can help your doctor evaluate the severity of your breathing issues. An FEV1 reading that’s lower than expected shows you might have a significant breathing obstruction. Your doctor will use your … See more One of the primary spirometry measurements is FVC, which is the greatest total amount of air you can forcefully breathe out after breathing in as deeply as possible. If … See more Doctors often analyze the FVC and FEV1 separately, then calculate your FEV1/FVC ratio. The FEV1/FVC ratio is a number that represents the percentage of your lung capacity you’re able to exhale in 1 second.
