作者首次用氩气替代昂贵难求的氦气作标准化一次呼吸法肺CO弥散量(D_LCO_(SB))测定获得成功。实验采用氩、氦分别或混合配制的3种混合气(A:10％He+0.3％CO;B:10％Ar+0.3％CO;C:10％Ar+10％He+0.3％CO)对118例正常人,48例患者
The authors first succeeded in using Argon for the replacement of expensive and difficult-to-use helium gas for standardized one-breath lung CO diffusivity (D_LCO_ (SB)). The experiment used three kinds of mixed gas (A: 10% He + 0.3% CO; B: 10% Ar + 0.3% CO; C: 10% Ar + 10% He + 0.3% CO) 118 normal people, 48 patients
