Preserved ratio impaired spirometry (PRISm ... with a focus on PRISm (forced expiratory volume in 1 second [FEV1]/vital capacity [VC] ≥ 0.70 and FEV1 < 80% of predicted value).

FEV1 is measured during a spirometry test ... involving FEV1 and another breathing measurement called forced vital capacity (FVC). FVC measures the greatest amount of air you can forcefully ...
