The performance of the Haloscale "Infanta" respirometer has been assessed in vitro using ISO test compliances and resistances, and in vivo by comparison with pneumotachograph volumes in 13 spontaneously breathing children and 13 children during intermittent positive pressure ventilation. The Infanta was shown to be capable of registering volumes between 15 and 200 ml with an accuracy of +/- 5%. The registered volume decreased rapidly below 15 ml, whilst above 200 ml over-registration developed.
已使用ISO测试顺应性和阻力在体外评估了Haloscale“Infanta”呼吸计的性能，并通过与13名自主呼吸儿童和13名接受间歇正压通气儿童的呼吸流速仪测量的容积进行比较，在体内评估了该呼吸计的性能。结果表明，Infanta能够记录15至200毫升之间的容积，准确度为±5%。记录的容积在15毫升以下时迅速下降，而在200毫升以上时则出现记录过量的情况。
