Lifelight (Xim)

NHS problem

Over 400M observations of patients’ vital signs are taken each year in the NHS, and the data produced is critical to screening, triage, monitoring, and detecting deterioration.

Each measurement requires trained staff to be physically present, takes over three minutes of clinical time, and requires specialist equipment. Many patients find elements of the observations distressing.

The solution

Lifelight allows any smartphone or tablet device to measure blood pressure, pulse and breathing rate simply by a patient looking into the device’s built-in camera for 40 seconds. Completely contactless, with no additional hardware needed, it saves NHS staff time while improving patient experience.


Today Lifelight is detecting patients at risk of CVD early, via self-service kiosks in Health Hubs. Offering patients the opportunity to check their blood pressure and if necessary access to the right care pathway. The platform:

  • Enhances flow, saving two minutes from every observation compared with traditional cuff
  • Improves patient experience, for example helping to reduce “white coat” syndrome which affects 15-30% of the population and costs £10.5M per year
  • Enables faster triage: patients arriving in urgent care centres can self-check-in with Lifelight integrated into remote consultation services
  • Enables remote triage, which can for example reduce out of hours call outs to care homes
  • Estimated savings in primary care alone of £42,000 per practice per annum (£332M NHS wide), according to an independent SBRI health economist report
