摘要:
The performance of instruments for measuring peak expiratory flow have been investigated. This evaluation was carried out with two designs of spirometer, two types of pneumotachograph and three versions of the Wright peak flow meter. The appropriate flow profiles were generated by means of a special type of flow calibrator. The errors produced by the instruments varied from zero to about 26%.
