This blood gas gets waved around a lot, particularly at unexpecting medical students and other impressionable individuals.
As an isolated result, this one is an abomination. Clinical scenarios with varying levels of improbability are offered to the interpreters. "This is an ABG collected during a cardiac arrest"; "This is a sample of peripheral venous blood from an unwell demented patient"; "This sample suffered prolonged transport time on the way to the laboratory". My favourite has been "This patient presented to emergency complaining of generalised unwellness, dry skin, hoarse speech, ataxia and compulsive brain-eating behaviour".
