I got PFT test. The results is like this:
MILD RESTRICTIVE VENTILATORY DEFECT. This is indicated by the finding of a mildly reduced forced vital capacity (FVC). The finding of a
disproportionately reduced forced expiratory flow during the middle half of exhalation (FEF 25-75) suggests the possibility of a
SUPERIMPOSED EARLY OBSTRUCTIVE PULMONARY IMPAIRMENT. This interpretation is valid only upon physician review and signature.
