Abstract
The commercialization of smartwatches and smart bands is boosting the presence of optical sensors located at the wrist. Initially aimed at monitoring heart rate, such photoplethysmographic (PPG) sensors contain additional worthwhile information that is currently unexploited: in particular, concerning blood pressure. CSEM started ten years ago developing algorithms to extract cardiovascular information out of PPG signals. Initially at the chest, and later extended to other body locations, CSEM's optical blood pressure monitoring (oBPM™) solution offers a toolbox to enlarge the capabilities of PPG sensor devices, enabling breakthrough blood pressure (BP) monitoring functionalities. To differentiate from other competitors, CSEM is currently validating oBPM™ algorithms in a cohort of anesthetized patients including invasive reference means, and involving very challenging hemodynamic variations.
