| Abstract | ||
| The effect of passive cigarette smoke exposure on the bronchial reactivity of 10 asthmatic patients was studied and compared with (10) apparently healthy people as control. Measurements of vital capacity (VF) and forced expiratory volume in one minute (FEVr) and pulmonary flow-volume curve (PF, FEF75, FEF5p,FEF25) were obtained before and after 30 minutes exposure to side-stream smoke in a simulated tobacco combustion chamber. Post exposure values were significantly reduced (p< 0.05) in all variables which were mole pronounced in astbmatic patient compared with contuol . FVC and FEY l tedtcedby 22.5To atd27.9% respectively. Air flow in mid (FEF so) and end (FEF25) airways was reduced by 32.5% arLd 45.8 % receptively such hndings clearly demonstrated the serious effect an the ventillatory function ofthe asthmatic patients exposed to a side-stream smoke in a relatively closed environment. | ||
