Abstract :
A median filter is combined with narrow adjustable monitoring limits and wide physiologically determined alarm limits. This ensures both quick alarming in the case of a catastrophic failure and reliable therapy monitoring with alarms. Results of the clinical assessment of this dual-limit alarmer are provided. Results of the clinical evaluation indicate a significant reduction in the frequency of false alarm (63% per patient hour)
