The new, low-range Ferraris pocket peak flow meter was compared with the well established low-range mini Wright peak flow meter for measuring peak flow rates in children. The peak flow meters were compared by performing three forced expirations using each meter, in 50 children. On average the pocket peak flow meter gave higher readings than the mini Wright, by a mean of 15 l/min. The peak flow rates obtained by the two meters were highly correlated (P < 0.001, r = 0.882 n = 50). In conclusion, the Ferraris pocket peak flow meter is easy and comfortable to use, giving reproducible measurements of peak flow in children.
将新型低量程法拉利袖珍式呼气峰值流量计与成熟的低量程迷你赖特呼气峰值流量计进行比较，以测量儿童的呼气峰值流速。对50名儿童使用每台流量计进行三次用力呼气，以此比较这两种呼气峰值流量计。平均而言，袖珍式呼气峰值流量计的读数比迷你赖特流量计高，平均高15升/分钟。两种流量计测得的呼气峰值流速高度相关（P<0.001，r = 0.882，n = 50）。总之，法拉利袖珍式呼气峰值流量计使用简便且舒适，能对儿童的呼气峰值进行可重复测量。
