Design outcomes

Primary

Measure	Time frame
Agreement between vital signs calculated by the snap40 wearable device and accepted measuring techniques is measured by vital signs from the snap40 wearable device and from the Draeger IACs and nursing observations continuously throughout the study.	—

Secondary

Measure	Time frame
1. Agreement between the snap40 wearable device and accepted measurement techniques at high and low reading levels is measured by vital signs from the snap40 wearable device and from the Draeger IACs and nursing observations continuously throughout the study 2. Agreement in changes in readings over time between the snap40 wearable device and accepted measurement techniques is measured measured by vital signs from the snap40 wearable device and from the Draeger IACs and nursing observations continuously throughout the study 3. Agreement between the calculation of a National Early Warning Score (NEWS) from readings taken by the snap40 wearable device to a NEWS score calculated from accepted measurement techniques is measured measured by vital signs from the snap40 wearable device and from the Draeger IACs and nursing observations continuously throughout the study	—
