Conversion of venovenous (VV) to venoarterial (VA) cannulation with a Y-connector tubing. Steps for conversion of VV to VA cannulation: 1) Continue with VV bidirectional flow while performing open cutdown and cannulation of carotid artery. 2) Once the carotid artery cannula is in place, clamp the inflow port on the VV cannula and allow inflow from the carotid artery cannula. 3) Attach Y-connector tubing to the VV dual-lumen catheter. 4) Unclamp the previous inflow port so that both ports are now connected to the extracorporeal membrane oxygenation circuit venous return.
