Abstract

|
|
It is well known that there is an adverse effect of long-term cigarette smoking on pulmonary function. Therefore we attempted to consider the vital capacity for position changes in a smokers and non-smokers. The pulmonary functions on sitting and supine positions were measured in 28 young healthy students for the change of vital capacity. Forced expiratory flow-volume curve were performed sitting position and supine position and smoking.
The results were summarized as follows;
1) The spirometric values(VC, FVC, FEV,) were progressively decreased from sitting position to 30 minutes after supine position in a non-smoking group(p<.05).
2) The VC, FVC, FEVi, FEF25----75% were decreased from sitting position to 30minutes after supine position in a smoking group(p< .01). The PEF and FEF25% were decreased from supine position to after smoking(p<.05).
3) Non-smoking group and smoking group not showed significant change(p> .05). But the spirometric values were more decreased nonsmokers than smokers.
