VV ECMO (short for veno-venous extracorporeal membrane oxygenation) is a type of life support used when a person's lungs are severely damaged and can’t provide enough oxygen to the body on their own. It’s like an artificial lung outside the body that gives the lungs time to heal.
VV ECMO doesn’t treat the underlying illness—it just buys time for other treatments to work or for the body to recover on its own. Think of it as giving your lungs the rest they need, while the machine does the work for them.
VV ECMO is primarily used for patients with respiratory illness. It works as the lungs.

An ECMO team, or group of specialists, are the ones who are called when someone is being considered for ECMO candidacy. This usually will involve a critical care doctor, a cardiologist, a pulmonologist, a surgeon, alongside nurses, respiratory therapists, and perfusionists. These are incredible, life saving professionals who dedicate their careers to keeping patients safe on such a complicated machine.
The ECMO team is the one who is called to see if a patient is a good candidate for ECMO. If this is decided, the patient can be placed on ECMO either in the cath lab, bedside, or in an operating room. This procedure takes a village, and these specialists are highly trained and knowledgeable healthcare providers here for you and your loved one.
As with any major invasive procedure or surgery, ECMO does come with risks. First, and most common, is the risk of bleeding. There is also a risk of blood clots, and in the most severe cases, poor blood-flow to a limb. This may result in further procedures that your doctor will go over with you. However, when someone is sick enough to be on ECMO, the benefits of the machine outweigh the potential risks, and ECMO has saved countless lives. It is the last chance.
This is daunting and scary, however at hospitals there are support groups, and a team there to help you and thoroughly explain risks and benefits of this procedure. Always remember to advocate for yourself and your loved one. Ask questions, the team is there to help!
There are many different indications for patients who are considered for VV-ECMO. First, the team is looking to see if there is still preserved cardiac function, VV ECMO primarily assists with the lungs. There are several considerations taken into account for patients- age, acuity, and pre-existing morbidities. Once this is all considered, here is who may be placed on VV- ECMO.
Acute Severe Respiratory Failure (both hypercarbic and or hypoxemic)
Acute Respiratory Distress Syndrome
Bronchopleural Fistulas
Complex airway management
Pulmonary air leaks
Respiratory Failure after a lung transplant
