Before 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 patient's efforts yield flattened flow-volume loops, submaximal effort is most likely; however, central or upper airway obstruction should be considered. Further lung function tests may well be based on previous results for the individual. Or it may be done as part of a longer stay in the hospital.
