Smartphone Application, Lifelight, Leads as First to Deliver Blood Pressure Readings with Medical-grade Precision
In a groundbreaking development for digital health, the Lifelight smartphone app has become the first in the world to receive Class II medical certification. This certification signifies that the app, which uses only a phone camera, meets specific regulatory standards for safety and effectiveness, placing it on a recognised medical device level.
The app's development, according to Lifelight CEO Laurence Pearce, is as significant as the smartphone camera was for photography, making clinical-grade cardiovascular screening available to everyone, everywhere.
Lifelight's innovative technology employs remote photoplethysmography (rPPG), which detects microscopic colour changes in the face caused by blood flow. This method offers a highly accessible and cost-effective alternative to traditional cuff-based monitors, potentially enabling more frequent and convenient blood pressure monitoring without the need for specialized equipment.
While traditional cuff-based monitors remain the established standard for accuracy, Lifelight's app represents a significant innovation by combining ease of use and certified accuracy. The app is already used by over 100,000 people across the UK and Europe, and its development holds potential for easing pressure on healthcare services by allowing accurate blood pressure readings to be taken at home.
The app is particularly valuable for individuals with obesity, mobility challenges, or those unable to use traditional cuffs. It is also significant for making clinical-grade cardiovascular screening available to everyone, everywhere, a step forward in preventative care.
In comparison to traditional methods, the Lifelight app offers likely lower costs since it uses existing smartphone hardware without the need for additional devices. Its accessibility is very high, as it requires only a smartphone camera, enabling widespread and convenient monitoring anywhere. However, the exact comparative accuracy data vs. traditional cuffs is limited in the public domain.
Lifelight's unique proprietary clinical rPPG blood pressure dataset consists of over 25,000 paired gold standard BP and video recordings. The company holds six patents related to these models, trained on a diverse dataset of 12,500 patients.
The app's potential impact extends beyond blood pressure measurement. Lifelight's technology is being considered for remote lung function monitoring, as demonstrated by the electronRx smartphone app launch. Digital health technologies are being used to empower interstitial lung disease patients, and the Lifelight app aligns directly with NHS priorities around preventative care and cardiovascular health.
With 80% of cardiovascular disease being preventable and 15% of Europeans living with undiagnosed hypertension, early detection can be crucial. The Lifelight app's ease of use and accessibility could play a significant role in early detection and prevention, potentially saving lives and reducing healthcare costs in the long run.
As smartphone technology continues to evolve, it is clear that it will play an increasingly important role in healthcare. The Lifelight app is a shining example of this potential, offering a convenient, cost-effective, and accessible solution for blood pressure measurement and, potentially, other health monitoring needs.
