1、肺功能指標(biāo)英文縮寫及臨床意義解析,Tidal volume 潮氣容積,TV,inspiratory reserve volume 補(bǔ)吸氣容積,IRV,expiratory reserve volume 補(bǔ)呼氣容積,EVR,residual volume 殘氣容積,RV,inspiratory capacity 深吸氣量,IC,functional residual capacity 功能殘氣量,FRC,Vital capacity 肺活量,VC,TLC,Total lung capacity 肺總量,FVC,Forced vital capcacity:用力肺活量：是指最大 吸氣（TLC位）后

2、以最大努力、最快速度呼氣 至完全（RV位）的呼氣氣量,FIVC：forced inspiratory vita cacapicity,用力吸氣肺活量,FEV1.0,Forced expiratory volume in one second,簡稱1秒量，最大吸氣至TLC位后第1秒內(nèi)的最快呼出氣量 FEV3.0 FEV6.0 FIV1.0,容積-時間曲線,Man 176 cm 76 kg,容積-時間曲線,FVC,流速-容量曲線,FEV1/FVC,1秒率，是判斷氣道有否阻塞 的最重要的指標(biāo),PEF，PEFR，PIF,Peak expiratory flow 呼氣峰流速 Peak expirator

3、y flow rate 呼氣峰流速變異率 PIF：peak inspiratory flow 吸氣峰流速,MVV,maximal voluntary ventilation 最大自主通氣量,MMEF，F(xiàn)EF25-75%, FET,Maximal mid-expiratory flow 用力呼氣中期流速 Forced expiratory flow 用力呼氣流量 FEF25-75% ，forced expiratory flow from 25-75% of FVC 呼出氣體25%-75%肺活量的平均流量 FEF200-1200 起始用力呼氣200ml-1200ml的平均流量 FET（Texp）

4、:forced expiratory time 用力呼氣時間,FEF25%， max75%, MEF75%,FEF25%：forced expiratory flow at 25% of FVC,用力呼出25%肺活量時的瞬間呼氣流量 max75%: maximal expiratory flow after 75% of the FVC has not been exhaled MEF75%: maximal expiratory flow after 75% of the FVC has not been exhaled,FEF50%， max50%, MEF50%,FEF50%：force

5、d expiratory flow at 50% of FVC,用力呼出50%肺活量時的瞬間呼氣流量 max50%: maximal expiratory flow after 50% of the FVC has not been exhaled MEF50%: maximal expiratory flow after 50% of the FVC has been not exhaled MIF50%: FIF50%： FEF50%/FIF50%1：胸外型上氣道阻塞,FEF75%， max25%, MEF25%,FEF75%：forced expiratory flow at 75% o

6、f FVC,用力呼出75%肺活量時的瞬間呼氣流量 max25%: forced expiratory flow after 25% of the FVC has not been exhaled MEF25%: maximal expiratory flow after 25% of the FVC has not been exhaled,FEF， max, MEF,DLco,Diffusion capacity for carbon monoxide 一氧化碳彌散量,Carbon monoxidetransfer factor determined in single breath,TIc
