WebThis problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: 7.) What is the FEF 50%/FIF 50% ratio … 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 your FVC is lower than expected, something is restricting your breathing. “Normal” or “abnormal” resultsare evaluated differently between … See more 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 … 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 … See more
