VV ECMO can be performed with different cannulation strategies. The use of two single lumen cannulas draining in inferior vena cava (IVC) and reinfusing in superior vena cava (SVC) or draining in SVC and reinfusing in IVC, or one dual lumen cannula inserted in right jugular vein is all possible cannulation .
Goal flow for VV ECMO (in adults) about 50-60 cc/kg/min. You can start at around 2 liters and titrate up, usually to a goal of 4-5 liters per minute. Start the sweep at about 2 lpm (for CO2 clearance) and titrate. Step 7: Clean up & confirmation.

11/11/2018 · The Avalon Elite ® is the most common dual lumen cannula used in contemporary VV ECMO , and many ECMO centers preferentially insert such catheters as the first choice cannulation technique for VV ECMO if possible. This is because dual lumen catheters for VV ECMO permit single site cannulation in the upper body.
Veno-Venous ECMO cannulation is commonly performed percutaneously with ultrasound guidance using Seldinger technique although surgical cut down may occasionally be required. Echocardiography or fluroscopy are used to confirm wire placement and cannula position. The access cannula is usually placed in the inferior vena cava via the femoral vein.
VV – ECMO circuits usually include the cannulation of two vessels (double cannulation ) in the classic configuration, the use of a single cannula is now possible for VV – ECMO support. Recently, expert centers have proposed the use of more advanced approaches, such as the cannulation Review Article, 12/6/2015 · Classically VV ECMO support is provided using two separate cannulation sites. More recently a single-site venovenous ECMO cannula has become available for sizes suitable for adults and children which allows mobilization of the patient due to lack of a femoral cannula . Choice of cannula size is critical to enable good support of the patient. One would like to provide diversion of 80% of the cardiac output on VV ECMO .
The double lumen cannula enables veno-venous extracorporeal membrane oxygenation ( VV ECMO ) to patients with severe respiratory failure. It is often used as a bridge to lung transplant. The cannulation is usually performed via the right jugular vein. This position allows the patients to stay awake and move around with the mobile ECMO system.
VV ECMO cannulation is a technically challenging and highly invasive procedure with high inherent risks for bleeding, tissue injury and air embolism. All staff undergo regular training, accreditation, supervision, and practice including in the animal lab to ensure the procedure is done in a standardised manner to minimize the potential risk to patients.
Veno-venous ( VV ) and veno-arterial (VA) extracorporeal membrane oxygenation ( ECMO ) therapy is widely used in critically ill patients with refractory cardiogenic shock and cardiac arrest or suffering from severe respiratory failure. Besides traditional ECMO cannulation , changes in patients’ condition.
6/15/2018 · V-V ECMO can be accomplished either through a dual-lumen cannula (with one draining canal and one infusion canal) or through two single-lumen cannulas. When the latter mode is used, possible configurations are femoral vein to IJV, IJV vein to femoral vein, and femoral vein (one side) to femoral vein (other side).
