Abstract
The presence of small gas bubbles in devices used to collect blood gas samples is considered. A gas bubble whose relative volume is 0.5 to 1% or more that of the liquid in the collection device is a potential source of significant error. Relationships describing the possible magnitude of this error are derived and substantiated.
摘要
考虑用于采集血气样本的设备中存在小气泡的情况。相对体积为采集设备中液体体积的0.5%至1%或更多的气泡是显著误差的潜在来源。推导并证实了描述该误差可能大小的关系。
