The Biobeat non-invasive, wireless monitoring device is based on reflective photoplethysmograph (PPG) technology. It measures several vital signs, including blood pressure, stroke volume, pulse rate, pulse pressure, heart rate variability, respiratory rate, saturation, cardiac output, cardiac index, and more. The data is transmitted to Biobeat's application (in both Apple and Google Play), and is available on the individual's cellular phone, tablet, or as a full monitoring system in a hospital department. The aim of this study is to compare the Biobeat monitor with the invasive method of blood pressure measurement, an arterial line, and a Swan Ganz catheter for measurements of cardiac output and stroke volume. The study population includes 20 patients undergoing cardiac surgery. As per local protocol, each one of the participants will come out from the operating room with an arterial line, some will also have a Swan Ganz catheter. Once in the intensive care unit, the investigators will attach the Biobeat non-invasive monitor (both a wristwatch and a patch), these two configurations are identical in terms of the monitoring system), and monitor the participants for 4 hours. Though both methods are continuous, the investigators will record the vital signs every 15 minutes during the 4 hours of the study.
