摘要
本文对176例健康成人和126例慢性阻塞性肺气肿患者测定了最大用力吸气流量—容积曲线(MFIV)和75例同时测定了MFIV和最大用力吸气口腔压(MIMP)。结果表明:与健康组比较,肺气肿各组MFIV各段流量均显著降低(P<0.01)和吸气时间显著延长(P<0.01),且随肺气肿的加重MFIV呈逐渐降低趋势。RV/TLC%与肺气肿组MFIV各段流量呈负相关(P<0.01),与吸气时间呈正相关(P<0.01)。75例MFIV各段流量与MIMP显著相关(P分别<0.05及0.01)。以上结果表明,MFIV可能是反映吸气肌功能的简便指标。
he maximal forced inspiratory flow volume(MFIV )of 176 health
subjects and 126 patientswith COPD were determined. It was found that all portions of MFIV
were significantly lower andthe inspiratory time was longer in patients with COPD than those in
the control(P<0.05~0. 001).Furthermore,the inspiratory flow volume in various COPD groups
tended to decreaswith thd increase of severity of the disease. The maximal Inspiratory mouth
pressure(MIMP)andMFIV in 75 normal male subjects were determined,and a marked
association of MIMP andMFIV was found. So,we conclude that MFIV might reflect the function of
respiratory muscles tosome extent.
