Screening for Postoperative Vital Signs Abnormalities, and Particularly Hemodynamic Ones, by Continuous Monitoring Using the Biobeat Patch

Detection of Postoperative Complications and Particularly Hemodynamic Ones Through Continuous Monitoring Using the Biobeat Patch

Brief Summary: Post-operative morbidity remains a reality as shown by the International Surgical Outcomes Study published in 2016 and 2019 and by several recent publications which focus mainly on hypotension and cardio-vascular complications. Other complications, such as respiratory depression, are less often studied. The hypothesis is that this connected patch could be used in surgical departments to detect a postoperative complication.

Biobeat Technologies Ltd has developed a sensor which continuously records the photoplethysmographic waveform and allows the calculation of several physiological parameters: heart rate (HR), oxygen saturation (SpO2), systolic blood pressure (SBP), diastolic blood pressure (DBP), stroke volume (SV), cardiac output (CO), cardiac index (CI), systemic vascular resistance (SVR), respiratory rate (RR), and temperature.

The objective of this study is the quantification of hemodynamic, respiratory and temperature abnormalities detected by routine monitoring (routine nursing follow-up) and continuous monitoring by the Biobeat patch during the first 72 postoperative hours.
