Supported by NHS England, Lifelight is a life-saving digital healthcare platform that currently measures blood pressure, heart and breathing rate simply by a patient looking into a tablet or a smartphone’s built-in camera for 40 seconds.
Lifelight works by detecting colour changes of the skin, not noticeable by the human eye, but detectable by a smartphone or tablet camera. With every heartbeat our face blushes, which is enough for a device camera to take key observations, including blood pressure, heart and breathing rates. These vital measurements can be taken with zero contact, the patient simply looks at the device screen.
Our ground-breaking solution, Lifelight First, available to clinicians today, has the potential to deliver benefits across a wide range of use cases. Our starting point is in primary and secondary care, where pressure on workload and staff shortages are critical. Lifelight reduces workload pressure by:
As well as staff productivity, the contactless nature of Lifelight has been reported to improve patient experience, and reduce anxiety as no cuff is needed. This may also help to reduce ‘white coat’ syndrome which affects over 15%-30% of the population  and leads to £10.5 million of unnecessary costs pa .
Lifelight First is intended for spot measurement of vital signs in clinical settings. Our next solution (in testing), Lifelight Home will allow patients to measure their own vital signs at home using their own smartphone. Lifelight Home overcomes the barriers to regular vital sign monitoring by people with chronic diseases by measuring the 5 major vital signs (heart rate, respiratory rate, blood pressure, oxygen saturation and atrial fibrillation – coming soon) using only the camera of any standard smart device (smartphone, tablet, laptop). All that is required is the user’s face to be in line of sight of the camera for 40 seconds, meaning they can be surfing the net, contributing to social media, etc. while having their vital signs measured.
