Clinical Trial Summary

The primary aim of the current study is to assess the effect of continuous wireless vital sign monitoring with generation of real-time alerts, compared to blinded monitoring without alerts on the cumulative duration of any severely deviating vital signs in patients admitted to general hospital wards after major surgery.

We hypothesize that continuous vital signs monitoring, and real-time alerts will reduce the cumulative duration of severely deviating vital signs.

Intervention

Device:
• Active Alarms
Intervention consists of actively alerting staff personnel if physiologic vital signs, deviates from certain thresholds for more than a set duration. Continuous vital sign data will also be available to clinical staff.
