Photoplethysmography (PPG) technology has come a long way since its inception. Initially used in the medical field to measure heart rate and blood oxygen levels, PPG technology has evolved dramatically over the years, thanks to advancements in artificial intelligence (AI) and the development of remote photoplethysmographic imaging (rPPG). Today, it is poised to revolutionize various industries and improve people’s lives worldwide.
The journey of PPG technology began in the mid-20th century. It was a simple, non-invasive method that used a light source and a photodetector at the skin surface to measure the volumetric variations of blood circulation. The technology was primarily used in pulse oximeters and cardiovascular monitors. However, its potential still needed to be fully realized.
The advent of AI in the 21st century marked a significant turning point for PPG technology. AI’s ability to analyze and interpret complex data patterns allowed for a more sophisticated use of PPG technology. This led to the development of rPPG, a contactless variant of PPG that uses a camera to measure red, green, and blue light reflection changes from the skin as the contrast between specular and diffusion reflections.
The Attune Health Mobile App is a prime example of this new generation of AI-powered, contactless PPG technology. As the all-in-one biomarker analysis app, it offers a comprehensive solution for tracking a wide range of wellness data. With just a video scan of the face, users can measure biomarkers such as blood pressure, heart rate, heart rate variability (HRV), oxygen saturation, breathing rate, sympathetic stress, parasympathetic activity, and pulse-respiration quotient (PRQ). It can also measure bloodless blood tests, Hemoglobin, and Hemoglobin A1C.
The app’s use of rPPG technology is groundbreaking. It measures the changes in red, green, and blue light reflected from the skin and quantifies the contrast between specular and diffused reflection. Light levels are processed to improve the accuracy of vital signs when required. Skin detection is performed on each region of interest (ROI), followed by extracting RGB values. Each vital sign is then calculated based on varying quantities of data, with results appearing within 10 seconds to 1 minute.
The implications of this technology are profound. It has the potential to revolutionize the health and wellness industries by making health monitoring more accessible and convenient. With the Attune Health Mobile App, users can measure biomarkers for their entire family using separate profiles, all from the comfort of their own homes. This could significantly improve preventive healthcare, as individuals can make informed decisions about their health based on real-time data.
Moreover, the technology could have a transformative impact on industries beyond healthcare. For instance, trainers in the fitness industry could use the app to monitor their clients’ vital signs during workouts, allowing for more personalized and effective training programs. In the corporate world, companies could use the app to monitor employee wellness, potentially reducing healthcare costs and improving productivity.
The development of AI and rPPG technology also opens up possibilities for remote patient monitoring in telemedicine, elderly care, and chronic disease management. It could enable healthcare providers to monitor patients’ vital signs remotely, reducing hospital visits and providing more timely care.
In conclusion, the evolution of PPG technology, driven by advancements in AI and the development of rPPG, is set to bring about a paradigm shift in health and wellness monitoring. The Attune Health Mobile App exemplifies the potential of this technology, offering a contactless solution that empowers individuals with the knowledge to make informed health decisions. As we move forward, we can see this technology being adopted more widely, changing the face of various industries and improving the lives of people around the world. The future of health and wellness monitoring is here, and it is contactless, convenient, and powered by AI.
