Abstract:
:The effect of smoking three cigarettes in rapid succession on maximal and partial expiratory flow rates was studied in ten healthy smokers. The mean decrease in maximal midexpiratory flow and partial midexpiratory and end-expiratory flow was statistically significant. The response was maximal after the first cigarette. These results suggest that the instantaneous midexpiratory flow after 50% of the forced vital capacity has been exhaled is a useful indicator of irritation of the airways. Reduction of partial expiratory flow rates was three times greater than reduction of maximal expiratory flow rates. We suggest the use of partial expiratory flow curves as a screening test for irritants of the airways.
