SurePulse Oximeter - a Targeted Oxygenation Observation

This clinical investigation will investigate how accurate the SurePulse VS and SurePulse VS Patch (VSP) are for measuring blood oxygen levels (oxygen saturation). If the results are accurate, the VSP will be ready to apply for regulatory approval, meaning it could then be available for use on newborn babies in the National Health Service (NHS).
