Abstract

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 O₂ sensors by pumping a gas of known O₂ 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
