We assessed the validity of several measures derived from the expiratory phase of the flow-volume curve obtained from spirometry to diagnose COPD: the slopes corresponding to the volume expired after the 50% and 75% of the FVC, the slope formed between the Peak Expiratory Flow (PEF) and the FVC, and the area under the expiratory flow/volume curve. %I Universidad de La Sabana %T Comparison of new spirometry measures to diagnose chronic obstructive pulmonary disease.
