    AbstractMost anesthesiologists, relying upon sales presentations from salesmen from oximeter manufacturers, believe that if an oximeter produces a steady signal with a good pulse amplitude, the numbers are always believable in the absence of interference from external light sources or from intravenous dyes. Here I report a case in which an oximeter appeared to be working properly yet displayed values which were falsely low. Trust in the oximeter resulted in delayed identification of the problem.
