摘要

便携式耗氧量计(Oxylog)在临床使用前的可靠性是通过比较从Oxylog和医学图形2001代谢车同时收集的数据来确定的，这些数据是在正常成年人休息和自行车测力仪运动期间收集的。结果表明两种系统的耗氧量和吸气通气量存在差异。建议通过泵送已知O/sub 2/浓度的气体通过设备，同时使用校准的注射器通过流量计引入已知的体积，从而经常检查O/sub 2/传感器，这将有助于消除对设备性能的担忧。

Evaluating the validity of the Oxylog in adults at rest and during exercise

The reliability of a portable oxygen consumption meter (Oxylog) before its clinical utilization is determined by comparing simultaneously collected data from an Oxylog and a Medical Graphics 2001 metabolic cart during rest and bicycle ergometer exercise in normal adults. The results indicate differences in oxygen consumption and inspiratory ventilation values between the two systems. It is proposed that frequent checks of the O/sub 2/ sensors by pumping a gas of known O/sub 2/ concentration through the device and, at the same time, using a calibrated syringe to introduce a known volume through the flowmeter will help eliminate concerns about the performance of the device.<>
