We present a case of oxygen analyzer malfunction diagnosed by the failure of the patient to adequately breathe oxygen as measured by end-tidal oxygen concentration. A warning icon, compliant with international standards, was not noticed at the time by those involved in the patient's care. The role of effective medical device user interface design is discussed.
