Tiffeneau-Pinelli index

The Tiffeneau-Pinelli index, also known as the FEV1/FVC ratio, measures lung function by comparing how much air someone can forcibly exhale in one second (FEV1) to their total forced exhalation volume (FVC). It helps assess whether airflow is obstructed, as seen in conditions like asthma or COPD. A normal ratio suggests healthy lungs, while a reduced ratio indicates airway obstruction. It’s a key diagnostic tool in respiratory medicine, providing a quick and reliable way to evaluate lung health.
