3M™ Bair Hugger™ Patient Warming System: Computational Fluid Dynamics study shows that Bair Hugger warming did not disrupt operating room airflow or move air from floor to surgical field
This video presents the findings of a scientific research project that shows the Bair Hugger Patient Warming System did not disrupt clean operating room airflow during a simulated hip replacement procedure. Using advanced mathematical calculations based upon the fundamental laws of physics, John P. Abraham, Ph.D., Professor of Thermal Sciences at the University of St. Thomas, found that air emerging from the Bair Hugger system did not disrupt the downward, clean operating room airflow that originates in the operating room ceiling, and did not move air from the floor to the surgical site. Dr. Abraham’s findings are confirmed by a separate operating room airflow visualization study, which is shown in a separate video. Both studies rebut claims from a competitor and a group of plaintiff attorneys that the warming system causes or increases the risk of surgical site infections by disrupting clean operating room airflow. Rather, in both studies, the Bair Hugger Patient Warming System did not disrupt clean operating room airflow and did not move air from the floor to the surgical site.
