  • A Stepwise Approach to the Interpretation of Pulmonary

    ResultsTreatmentExampleRisksPrognosisDiagnosisBefore PFT results can be reliably interpreted, three factors must be confirmed: (1) the volume-time curve reaches a plateau, and expiration lasts at least six seconds (Figure 2); (2) results of the two best efforts on the PFT are within 0.2 L of each other (Figure 3); and (3) the flow-volume loops are free of artifacts and abnormalities.5 If the patientefforts yield flattened flow-volume loops, submaximal effort is most likely; however, central or upper airway obstruction should be considered. The first step when interpreting PFT results is to determine if the forced expiratory volume in one second/forced vital capacity (FEV1/FVC) ratio is low, indicating an obstructive defect. Physicians have two options to determine if this ratio is low.
