For reduction the working extent in measurement and classification of flow-volume curves a device was developed which calculates and indicates digitally the maximal expiratory flow values PEF, MEF 75, MEF 50 and MEF 25 directly from the flow in forced expiration. We have used an approaching calculation method whereby the expense of realization was low. By a comparative examination of 172 patients, it could be found that the device has a sufficient measuring accuracy and is advantageously applicable to clinics and screening.
为了减少流量-容积曲线测量和分类中的工作量，开发了一种装置，该装置可直接根据用力呼气时的流量数字计算并显示最大呼气流量值PEF、MEF 75、MEF 50和MEF 25。我们采用了一种近似计算方法，实现成本较低。通过对172例患者的对比检查发现，该装置具有足够的测量精度，适用于临床和筛查。
