Abstract
The assessment of a new bellows spirometer against a water spirograph showed: slight alinearity, minimal overestimation of FVC (1.7%) and underestimation of FEV 1-0 (2.9%) as well as of the ratio FEV 1-0/FVC (4.8%). The main advantages of the instrument are: lightness, easy operation, ruggedness and low cost; it seems mainly indicated for use in large scale field surveys.
摘要
将一种新型风箱式肺活量计与水肺量计进行对比评估发现
存在轻微的非线性，用力肺活量（FVC）略有高估（1.7%），第1秒用力呼气容积（FEV₁₋₀）和FEV₁₋₀/FVC比值分别略有低估（2.9%）和（4.8%）。该仪器的主要优点是：轻便、操作简便、坚固耐用且成本低廉；似乎主要适用于大规模现场调查。
