Cough in 47-yr-old woman

Test Result 1

Results of pulmonary function testing return and show the following:

On room air:

  • Normal forced vital capacity (FVC)
  • Forced expiratory volume in 1 sec (FEV1): 60% of predicted
  • Peak expiratory flow (PEF): 65% of predicted

After administration of inhaled albuterol:

  • FEV1: 80%
  • PEF: 75%

Findings are consistent with reactive airway disease, possibly cough-variant asthma.
