Application of imaging photoplethysmography in surgical procedures: A review article

Abstract

Imaging photoplethysmography (iPPG) is an emerging non-invasive monitoring technology that has gained significant attention in recent years due to its numerous advantages, including safety, simplicity, and cost-effectiveness. With the continuous advancement of surgical techniques, there is an increasing demand for accurate and reliable monitoring tools in the operating room. Traditional monitoring methods often fall short in addressing the complexity of surgical procedures. In this context, iPPG has shown promising potential in various surgical applications, such as intraoperative monitoring, postoperative recovery assessment, and the prevention of complications. This paper reviews the current clinical applications of iPPG, highlighting its advantages and limitations. We also examine related research and discuss future directions to further integrate iPPG into surgical practice, with the ultimate goal of improving patient safety and surgical outcomes.
