Vital Signs Monitoring with Wearable Sensors in High-risk Surgical Patients A Clinical Validation Study

Conclusions All sensors were highly accurate for HR. For RR, the EarlySense, SensiumVitals sensor, and Masimo Radius-7 were reasonably accurate for RR. The accuracy for RR of the HealthPatch sensor was outside acceptable limits. Trend monitoring with wearable sensors could be valuable to timely detect patient deterioration.Editor ’s PerspectiveWhat We Already Know about This TopicChanges in vital signs are an important indicator of physiological decline and hence provide opportunities for early recognition and intervention; however, in the hospital ward, vital signs are usually measured intermittently. In between such spot checks, early signs of deterioration may be missed.Several “wearable” and wireless sensors have been developed that may capture the patient deterioration earlier.What This Article Tells Us That Is NewIn high-risk surgical patients admitted to a step-down unit, heart rate was accurately measured by the two wearable patch sensors (SensiumVitals [Sensium Healthcare Ltd., United Kingdom] and HealthPatch [VitalConnect, USA]) and by the bed-based contactless mattress sensor (EarlySense [EarlySense Ltd., Israel]) and by the patient-worn monitor (Masimo Radius-7 [Masimo Corporation, USA]). The highest precision for heart rate was seen with the HeathPatch sensor.For respiratory rate, the accuracies of the Masimo Radius-7, EarlySense, and SensiumVitals were within a predefined acceptable range, while the HealthPatch overestimated respiratory rate.
