The study will take place in the ICU (Intensive Care Unit) or in the CICU (Cardiac Intensive Care Unit) units, on non-anaesthetized subjects with an arterial line inserted into the radial artery. Continuous recording will be performed in parallel using invasive arterial line recording and CardiacSenseBP1 non-invasive recording. The ECG data recorded in the ICU will also be obtained. .
Up to 80 subjects will be included in the study.
The subject will possibly be connected to the CardiacSense1BP device a few times to check repeatability. The first measurement will be of up to 24h. Subsequent measurements will be of up to 5h. Data analysis will be performed offline.
Data is collected for CardiacSense1BP device algorithm development.
