Vents Quest's Vacuum Relief Valves are designed to facilitate safe left ventricular venting during on-pump heart surgeries. The triple action vent valves relieve excess negative pressure, prevent retrograde flow, and relieve excess positive pressure in the left ventricular vent line.


Where to use the VRV-IIC, VRV-II or RLV:


  • Aortic Root Venting
  • Suction Line
  • Direct Venting
  • Autotransfusion Line
