Frc on spirometry
WebSep 22, 2024 · The FEV1/FVC is a ratio that reflects the amount of air you can forcefully exhale from your lungs. It's measured by spirometry, a test used to evaluate lung function. The FEV1/FVC ratio is often used in diagnosing and monitoring the treatment of lung diseases such as chronic obstructive pulmonary disease (COPD). WebMar 5, 2024 · Interpreting Results . Again, ERV is not a separate test but rather one of several measurements of lung function obtained from spirometry. It is determined after a key measurement of lung volume—functional reserve capacity (FRC)—has been measured.FRC refers to the volume of air left in the lungs after a normal, passive …
