Clinical trials

This study aims to validate the accuracy and reliability of blood pressure (BP) estimates obtained over 24 hours using a PPG-based chest-patch device compared to the gold standard ambulatory blood pressure monitoring (ABPM) method using an upper arm cuff-based oscillometric BP device, in both hypertensive and normotensive individuals referred by their provider to undergo a 24-hours ABPM for clinical indication. The Awake/Asleep test, which is the primary test recommended for automated wearable cuffless BP devices that are cuff-calibrated (based on the 2023 European Society of Hypertension (ESH) recommendations for the validation of cuffless blood pressure measuring devices), will be conducted in this study. The secondary aim of the study is to assess the feasibility and convenience of the PPG-based device.

In this clinical study the investigators will compare blood pressure measurements obtained using the non-invasive, wireless Biobeat monitoring device (both a wrist watch and a patch configuration) to an invasive arterial line catheter (radial or femoral) and a Swan Ganz Catheter in 20 patients immediately after cardiac surgery, at the cardiac intensive care unit.
