What is Lifelight?

Supported by NHS England, Lifelight is a life-saving digital healthcare platform that measures a person’s vital signs for use in critical healthcare areas including infectious disease detection and control, long-term condition monitoring and remote primary care consultations. Lifelight allows healthcare providers to get accurate vital signs in one 40 second reading, just by the patient or user looking into a smartphone or tablet device, with no additional hardware needed.

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 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.  How does Lifelight Work?

A key goal of the NHS Long-Term plan is to offer patients remote consultations.  With this need accelerated by Coronavirus, Lifelight is moving forward to play a key role, allowing clinicians to know a patient’s vital signs remotely, accurately and in real time. Equipping them to effectively assess the physical condition of the patient for an improved outcome.

Where can Lifelight be used?

Clinically validated and regulatory approved, Lifelight delivers benefits across a wide range of use cases whether stand-alone or at scale. With its transformative ability to measure vital signs simply using the patient’s own smartphone, Lifelight removes the cost and complexity of hardware blood pressure cuffs and pulse oximeters. It is able to be embedded into existing healthcare platforms and pathways, allowing them to be more efficient, more effective and more scalable.  More importantly it enables existing digital health pathways to be revisited, revised and reengineered.

At the heart of Lifelight are patented AI algorithms that allow Lifelight to deliver continually improved accuracy of vital signs.  Built to rigorous medical grade ISO 13485 and IEC 62304 standards Lifelight is engineered to the highest standards.

Lifelight can support the entire healthcare ecosystem from pre-primary care, through primary and secondary to, critically during a pandemic, care homes – saving clinical time, informing remote consultation, allowing residents to be cared for effectively and efficiently by a known carer – and beyond, to improving healthcare itself. Wherever vital signs are needed Lifelight is needed.

Pre-Primary Care

Population Screening – allowing at volume identification of healthy people who may have an increased chance of a disease or condition.
Lifelight allows the needed reduced physical contact and advance screening at scale:

  • Track & Trace Screening – governments needing to bolster existing healthcare applications through alerts or supporting employee “back to work” programmes
  • Personal Screening – supporting the need for self-care by enhancing wellness applications with Lifelight’s clinically validated vital signs. Lifelight can be embedded into existing wellness apps and/or delivered B2B via Insurers and/or EAP providers to users/employees
  • Vaccination Centres – a specific, topical use case – screening overall health status via vitals or to support screening for a specific health risk, i.e. Cardiovascular Disease (CVD) whilst visiting for Covid or other vaccinations

Primary Care

A key market driver, especially given the ongoing COVID-19 pandemic is the ability for patients, with clinician’s guidance, to self-monitor at home.  Patients are assured their key vital signs are being remotely monitored and regularly fed directly back into their patient record, allowing the right care pathway to be actioned quicker.  Lifelight overcomes the barriers to regular vital sign monitoring for people with chronic diseases by measuring their key vital signs.

For the patient it means the obvious benefits of less appointments and a much-improved patient experience and for healthcare organisations, fewer appointments, less paperwork and for both better patient outcomes.

Ultimately, we’re working to allow true self-care, allowing us all to regularly self-monitor from any device.  Saving lives and keeping as many of us well and out of hospitals provides us with best reasons to deliver Lifelight to all.

Virtual Consultations – in Primary Care Lifelight can used by a patient with a smartphone whilst in a ‘virtual waiting room’ in advance of an online consultation, or by a GP or nurse in-practice using a tablet. Lifelight can also be embedded into existing telehealth platforms to enable Video Consultations or directly into Electronic Health Record (EHR) vendors (see Partner section):

  • Virtual waiting room
  • Live consultations
  • Rapid triage / onward referral

Secondary Care

Remote Patient Monitoring – improves outcomes by allowing regular remote monitoring of vital signs to fight chronic disease and better access for all to healthcare via an everyday smartphone or tablet:

  • Long-term condition (LTC) management
  • Remote pre-op assessment, eliminating wasted journeys for patients and clinical time
  • Early discharge monitoring

Care home, domiciliary & mental healthcare providers

Regular vital signs monitoring in social and mental healthcare is ever critical but more so during a pandemic. Lifelight enables key data to be shared remotely with clinicians without physical contact, without any stressful travel and avoids unnecessary hospitalisations.

Read NHSX’s social care case study of Lifelight with Hampshire Hospitals NHS Foundation Trust on how they responded to COVID-19.  Lifelight is enabling remote patient vital signs monitoring to continue safely with minimal contact and travel for patients and service users in a nursing home, a care home and a step-down facility.

Healthcare Improvement

  • Clinical trials, including Clinical Research Organisations (CROs) – important clinical trials can be done remotely by collecting observations from the participant’s mobile device
  • Population monitoring to drive and inform healthcare strategy and policy.

How Lifelight drives workplace efficiency & saves money

Lifelight delivers system-wide efficiencies favouring faster and more accurate observation taking, leading to clinical workforce transformation while improving patient experience.  COVID-19 has highlighted the value of remotely monitoring patients safely and at volume, resulting in high demand for Lifelight globally – Lifelight’s vision is to turn every device on the planet into a self-monitoring healthcare platform.

Our starting point is in primary and secondary care, where pressure on workload and staff shortages are critical. Lifelight reduces workload pressure by:

  • Improving throughput of consultations.  Blood Pressure measurements are taken in 31% of England’s 372 million annual GP appointments [1].  Reducing the time taken for these could free up more than 4 million hours of GP and Practice Nurse time.

  • Reducing care home and home visits.  The average surgery makes 27 home and 13 care home visits weekly, which consumes considerable clinical time, whereas Lifelight can be provided to frequent service users to make better informed remote consultations.

  • Easier capture of vital signs across all care settings leading to improved detection of sepsis and other forms of health deterioration.

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 [2] and leads to £10.5 million of unnecessary costs pa [3].

“Lifelight is estimated to save over £300m a year for NHS reinvestment, if used in GP surgeries alone.”

Lifelight Home & Futures

We’re continually working to add additional vital signs to the solution to best support patients and clinicians to give an holistic view of someone’s overall health.  As well as this continual development we’re also investing in ongoing research, including bespoke requirements, forever broadening the feasible applications of Lifelight.

Lifelight is currently intended for spot measurement of vital signs under direct clinical supervision, be that remotely or in a clinical setting. Our next iteration due very soon, Lifelight Home, will allow patients to measure their own vital signs at home using their own smartphone. Whilst allocating Lifelight Home to a patient would be within a clinical pathway, its usage would not be directly clinically supervised. Lifelight Home overcomes the barriers to regular vital sign monitoring by people by measuring their vital signs (heart rate, respiratory rate, blood pressure, oxygen saturation and atrial fibrillation  – coming soon) when they need to conveniently, without undertaking a journey, without engaging with a clinician.

FAQs – Common Questions

What is PPG & rPPG?2021-08-15T00:58:33+01:00

Photoplethysmography (PPG) is a non-invasive optical technique that detects blood volume changes in the microvascular tissue bed beneath the skin[1].

Widely used in pulse oximeters to monitor a subject’s heartrate and peripheral oxygen saturation (SpO2), PPG relies on the fact that arterial blood displays different optical absorption with respect to other tissue components in certain light wavelengths[2]. By emitting light through the skin layers and measuring the amount of light propagating in the tissue, we can obtain a PPG signal that reflects blood volume changes over time. The PPG-waveform can further be used to calculate physiological variables such as heartrate, respiratory rate, SpO2 and blood pressure. As well as use in medical applications, contact-based PPG has been adapted for use in some consumer-oriented wearable devices.

Remote PPG (rPPG) is an evolution of PPG technology that no longer requires physical contact, relying instead on ambient light being reflected from the skin and captured remotely by a CMOS camera[3][4]. The colour signals captured can then be filtered using AI techniques such as Independent Component Analysis (ICA) [5].

Lifelight’s technology is a practical application of rPPG using ubiquitous mobile phones and tablets for static non-contact health monitoring of patients/consumers, eliminating the need for additional devices.

Why does Lifelight need to know a person’s age and height?2021-08-15T00:52:50+01:00

The patient’s age, height and sex are captured to help the Lifelight First algorithm to accurately calculate systolic and diastolic blood pressure.

It is important to emphasise that although the Lifelight First application captures height age and sex, it is not associated with the patient as there is no other personal identifiable data captured – e.g. name, email address, NHS number, fingerprint, etc.  The device will wipe this information immediately after Lifelight First has sent the RGB stream to the Amazon Web Service (AWS) for processing.

Does make-up limit Lifelight?2021-08-15T00:53:42+01:00

No, in fact during our clinical trials make-up was found to aid the device camera by cancelling out unwanted light on the face.
