dc.description.abstractFor more than ten years, CSEM has been a pioneer in the development, implementation, and validation of novel solutions for non-invasive continuous blood pressure (BP) monitoring. One of the central devices in CSEM's catalog on BP-monitoring is a multi-wavelength reflective photoplethysmogram (PPG) sensor that allows to accurately estimate BP at the chest. As a part of the validation procedure to characterize the sensor's performances in an acute setting, CSEM is conducting a clinical trial on anesthetized patients in collaboration with the Lausanne University Hospital (CHUV). The results demonstrate that in the acute conditions a widely-used conventional single-wavelength approach remains unreliable, while the innovative multi-wavelength device considerably increases the BP-estimation performances.
