The Airflometer provides a useful index of expiratory flow rate and as such it is a worthwhile advance. It can provide an accurate index of FEV1 provided it is individually calibrated. Perhaps the only limitation is the lack of response of the instrument at low flow rates, for example, with an FEV1 of less than one litre. It is remarkably inexpensive.
气流计提供了一个有用的呼气流量指标,因此是一项值得的进步。如果进行单独校准,它可以提供准确的第一秒用力呼气容积(FEV1)指标。也许唯一的局限性是该仪器在低流量时反应不足,例如,当FEV1小于1升时。它非常便宜。
