Description

Alarms from Vital Signs Monitors are a major distraction when over 95% are not critical. We report a practical alarm reduction method by delaying and changing specific vital signs (VS) alarm limits based on the analysis of the frequency and duration of patient monitor alarms in the neurointensive care unit (NICU). There were 671,889 alarms (8,393 hours) recorded during the study period resulting in 339 alarms per bed per day. By comparing the alarm amount in the past 8 weeks without changing alarm settings and the later 8 weeks, analysis of alarms with different limit settings based on 2 seconds collection VS showed that by changing the current NICU alarm threshold settings of SpO2 low to SpO2≤88%, tachycardia to HR≥135 bpm, and SBP high to SBP≥185 mmHg, the alarm frequency could be reduced by 46%, 42%, and 19%, respectively.

Describe the new knowledge and additional skills the participant will gain after attending your presentation.: how to evaluate neural ICU alarms; specific alarm reduction strategies based on big data analysis;
