Can you oxygenate blood externally?

Can you oxygenate blood externally?

ECMO stands for extracorporeal membrane oxygenation. The ECMO machine is similar to the heart-lung by-pass machine used in open-heart surgery. It pumps and oxygenates a patient’s blood outside the body, allowing the heart and lungs to rest.

What are the two types of ECMO?

There are two types of ECMO, venovenous (VV) and venoarterial (VA) (figure 1 and figure 2 and figure 3). VV ECMO is used in patients with respiratory failure, while VA ECMO is used in patients with cardiac failure.

What are the four types of ECMO?


  • VV = veno-venous.
  • VA = veno-arterial: peripheral or central.
  • Veno-pulmonary artery ECMO (provides short-term right ventricular and respiratory support following LVAD insertion)
  • high (2 venous cannulae) vs low flow (1 venous cannula)

What is the difference between VA and VV ECMO?

ECMO, Extra Corporeal Membrane Oxygenation. VA ECMO provides both respiratory and hemodynamic support; the ECMO circuit here is connected in parallel to the heart and lungs, while in VV ECMO the circuit is connected in series to the heart and lungs. During VA ECMO, blood will bypass both the heart and the lungs.

What is the only way to oxygenate the blood?

You can increase the amount of oxygen in your blood naturally. Some ways include: Open windows or get outside to breathe fresh air. Something as simple as opening your windows or going for a short walk increases the amount of oxygen that your body brings in, which increases overall blood oxygen level.

What is the difference between ECMO and ECLS?

The abbreviations ECLS and ECMO are used synonymously to mean prolonged extracorporeal circulation with mechanical devices. ECLS can be used for mechanical assistance during cardiac or pulmonary failure occurring in newborn infants, older children, or adults.

Where is VV ECMO placed?

V-V or veno-venous ECMO, supports lung function primarily. The surgeon will place the cannulae in a large vein only, usually in the neck. Based on the patient’s age and condition, the surgeon may choose to place one special cannula in a single vein or place two cannulae in two different veins.

What is VAV ECMO?

Veno-arterio-venous ECMO (VAV). VAV-ECMO drains venous blood (blue) from the right atrium and returns balanced volumes blood after reoxygenation and decarboxylation (red) to the iliac artery toward the aorta and to the right atrium toward the pulmonary circulation.

What is North South Syndrome?

Harlequin syndrome, also known as “North–South Syndrome” or “Dual Circulation,” occurs when there is an area of watershed within the aorta where the ECMO oxygenated blood from the femoral artery meets the low oxygenated blood from the impaired lungs, during peripheral VA-ECMO.
