The UK’s NHS is continuing its experiments with wearable tech with two trials of Snap40, a health wearable worn on the upper arm, which continuously monitors hospital patients’ vital signs.
The wireless device packs six sensors, which track heart rate, respiratory rate, temperature, oxygen saturations, blood pressure, posture, movement and even emotion. Snap40 will be used with 500 patients across two hospitals in Fife and Edinburgh, Scotland in April and May.
The data is transferred via Wi-Fi twice a minute and then put through machine learning algorithms before doctors and nurses view it on smartphone apps to analyse any changes i.e. how stable each patient is. The idea of the early warning system is that hospital staff can prevent patient’s conditions worsening, reduce hospital stays and save doctors and nurses having to manually monitor vital signs.
