✦ Synopsis

A cardiovascular alarm system formed part of an on-line real-time computer based physiological monitoring and measuring system in a post cardiac surgical intensive care unit. The incidences of false alarms was, as with other monitoring apparatus, disturbing. A detailed analysis of the causes in a clinical situation was carried out. This instanced their frequency, and confirmed that all arose at patient or patient-sensor interface levels. A postulate which might eliminate most of these was devised, and its feasibility tested over an extended period by a second detailed study. As a result, an alarm is now only sounded in response to coexistent changes in both heart rate and vascuIar pressure. The rationale of this scheme is considered. The compromise, while of limited usefulness, appears to offer practical advantages in the application of automated monitoring.
