Abstract

A computer-based system was used to collect and analyze data from five routinely used operating room monitors in order to identify meaningful alarm conditions and reduce the number of false positive alarms. Several methods for reduction of false alarms were implemented (patient-dependent limits, multivariable analysis and rate of change). The system was tested using operating room data from 21 surgical cases. The integrated monitor was able to correctly identify 10 of 11 intubations. Recognition of intubation was used in detection of false end-tidal-CO₂ alarms, reducing them by 70%. False heart-rate alarms were reduced by 68% using multivariable analysis and rate-of-change limits
