Web photoplethysmography: opportunities and prospects

Abstract

This literature review is devoted to the possibilities of using in clinical practice a new modification of photoplethysmography – its web version. The use of modern innovative techniques in the form of photo/video fixation of the human skin allows for contactless and remote assessment of the main physiological indicators of human health. This approach is of particular importance in conditions of shortage of medical workers, territorial separation of doctors and patients, restrictions in visiting medical institutions in the event of epidemics/pandemics of infectious diseases and it contributes to the development and implementation of telemedicine technologies in the daily work of medical specialists. The article discusses the possibilities of using web photoplethysmography to assess microcirculation (web capillaroscopy), heart rate and other indicators (respiratory rate, pulse rate, saturation, body temperature, etc.). Web photoplethysmography is a sensitive, simple and effective method of registering vital body functions. Its effectiveness as a possible screening method for detecting rhythm disturbances and its prospects in using blood pressure measurement has already been proven. The possibility of using not only video, but also photographic materials, for example, for the detection of cardiovascular diseases, is also described. No less promising is the possibility of using the method in conjunction with thermometry. The importance of studying aspects of web photoplethysmography is seen in the need to activate the processes of import substitution and technological sovereignty, as one of the main paradigms of our country’s development. It is obvious that the development of contactless research methods is one of the priorities in modern healthcare. Given the widespread availability of various devices, it is necessary to further explore the possibilities of using webcams and mobile devices in medical practice. The development and introduction into routine practice of medical devices that allow remote non-invasive early diagnosis of chronic non-communicable diseases is of special interest.
