title: Bubbles in samples for blood gas determinations. A potential source of error.
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.
