Clinical aspects of using remote sensing photoplethysmography: a narrative review

The paper analyzes the aspects of clinical use of an evolutionary method of sensing photoplethysmography in its remote version. Innovative approaches to assessing human health parameters using photographic and video recordings of human skin seem promising for telemedicine. This narrative review illustrates the possibilities of using remote sensing photoplethysmography to assess the health status of patients with cardiovascular, respiratory, and nervous system pathologies and other cases related to diagnosing and treating non-communicable diseases. This method has proven its efficiency as a promising screening tool for analyzing respiratory rate, pulse, diagnosis of rhythm disturbances, assessing tidal volumes, cerebral hemodynamics, skin integrity, etc. The authors emphasize the possible use of photo- and video materials, e.g., to detect cardiovascular diseases. Modern healthcare prioritizes the development of remote examination methods, excluding direct contact with the patient. It seems important to further examine the possibility of using web cameras and mobile devices in medical practice for early disease diagnostics, routine screening, and preventive medicine.
