Synthetic photoplethysmographic waveform at the radial artery

Obesity is a significant risk factor for development and management of cardiovascular disease, one of the leading causes of death in the United States. Blood pressure (BP) is a key factor for monitoring cardiac health. In support of design and development of wearable health devices, we have developed a model to generate synthetic photoplethysmographic waveforms captured by a commercial device for the radial artery at the volar surface of the wrist. We focus on impacts to the PPG signal as a result of various changes attributed to obesity, epidermal melanin, and vascular layers.
