摘要
目的探讨吸烟对检查对象肺功能的影响,总结其规律性,寻求可能的干预方法。方法选择2010年1～12月到笔者所在医院体检的研究对象共255例。吸烟组135例,非吸烟组120例。按常规检查肺功能,检查第1秒用力呼气容积(FEV1)、用力肺活量(FVC)、FEV1/FVC、最大呼气中期流速(MMEF)、75%、50%、25%肺活量位的最大呼气流速(MEF75、MEF50、MEF25)、呼气峰流速(PEF)。结果反映肺功能的指标FEV1、FEV1/FVC、MMEF、PEF、MEF50等在吸烟组明显下降,两组比较第1秒用力呼气容积(FEV1)、用力肺活量(FVC)、FEV1/FVC、最大呼气中期流速(MMEF)、75%、50%、25%肺活量位的最大呼气流速(MEF75、MEF50、MEF25)、呼气峰流速(PEF),差异均有统计学意义(P<0.05)。结论吸烟者在尚无临床症状时,其肺通气功能已明显下降,肺功能的变化受吸烟影响,较长期大量吸烟的人的肺功能的减退尤为明显。
Objective To investigate the pulmonary function tests in normal smoking patients, summarize its regularity, and seek possible interventional methods.Methods 255 cases who had been physically examined in the hospital from January 2010 to December 2010 were randomly selected and divided into 2 groups. There were 135 cases in smoking group and 120 in non-smoking group. Their pulmonary function such as FEV1, FVC, FEV1/FVC, MMEF, MEF75, MEF50, MEF25, and PEF were detected.Results The indicants such as FEV1, FEV1/FVC, MMEF, PEF, and MEF50 which reflected pulmonary function in the smoking group had significantly decreased compared with the non-smoking group. And the indexes of FEV1, FVC, FEV1/FVC, MMEF, MEF75, MEF50, MEF25, and PEF in the smoking group had significantly decreased compared with the non-smoking group. The difference was significant(P<0.05).Conclusion Although smoking patients do not show clinical symptoms, their pulmonary functions have been reduced. The alteration of pulmonary function of smoking patients, especially long-term ones, are affected by smoking, and their pulmonary functions decrease significantly and quickly.
