Brief Summary
The study aims to develop a novel perioperative noninvasive delivery of oxygen (DO2) and hemodynamic index in the prediction of postoperative outcomes including post-operative acute kidney injury (POAKI), perioperative neurological cognitive disorders (PONCD) and post-operative atrial fibrillation (POAF). Our study also aims to study the effect of DO2 and hemodynamic parameters (measured noninvasively) on the development of PONCD, POAF and POAKI in cardiac surgical patients. We aim to develop a novel DO2 index and hemodynamic index predictive of PONCD, POAF and POAKI. The secondary aim would be to develop real-time machine learning aided algorithms in the analysis of noninvasive continuous hemodynamic and DO2 data, to predict and guide perioperative treatment of POCND, POAF and POAKI in the perioperative setting.
