Vacuum-assisted venous drainage (VAVD) is a technique used to increase venous return during cardiopulmonary bypass (CPB). However, VAVD has created some new safety concerns. One potential problem is the pressurization of the venous reservoir in the event of vacuum failure. To prevent this overpressurization, a positive pressure release valve (PPRV) is placed on the venous reservoir. The purpose of this study was to determine if there is a difference in the pressurization of venous reservoirs… CONTINUE READING
