Using Technical Filtering and Clinical Criteria to Reduce Vital Sign Alarms Using Continuous Monitoring in the Ward

"The following monitoring devices are included in the WARD monitoring system (as intervention):~Isansys Life Touch patch: Measures heart rate (HR), respiratory rate (RR) and electrocardiogram (ECG)~Wearable, wireless Pulse Oximeter (Model 3150 WristOx from Nonin): Measures peripheral oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR)~Blood pressure monitor (Meditech BlueBP-05): Measures BP every 30 minutes during daytime and every 60 minutes during the night~All included patients are set up with the monitoring devices after surgery when they are back at their ward (with a maximum of 24 hours postoperative). Afterwards they wear the devices for up to 5 days. All measurements are sent through bluetooth to a tablet serving as a gateway which in turn sends data to a central server where the algorithmic processing ensures."
