Extracorporeal membrane oxygenation (ECMO) is a life-support technique that takes over the work of a failing heart, lungs or both, giving the organ time to recover or until it can be replaced. Kauvery Hospital’s multidisciplinary ECMO team in Chennai has performed more than 370 ECMOs and specialises in awake ECMO, where suitable patients stay awake, communicate and take part in physiotherapy during treatment.
Extracorporeal membrane oxygenation (ECMO) is a life-supporting device, similar in principle to the heart-lung machine used in heart surgery. It is used when a person’s heart, lungs or both are failing and need help to keep the person alive until the affected organ recovers or is replaced.
ECMO is used in critical care settings such as the intensive care unit (ICU), where a team of specialists monitors the patient closely. It is a complex and powerful tool, often considered when other treatments have not worked.
ECMO does the work of the lungs, the heart or both outside the body, so the organs can rest and heal while the underlying illness is treated.
Blood is taken out of the body through a tube and passes into a machine that adds oxygen and removes carbon dioxide, just as healthy lungs would. The machine then pumps the oxygen-rich blood back into the body, helping the brain and other organs keep working properly.
Blood leaves the body through a tube placed in a large vein, usually near the groin or neck.
The ECMO machine acts as an artificial lung. Blood flows across a membrane that adds oxygen and filters out carbon dioxide.
Oxygen-rich blood is returned to a vein (VV ECMO) or to a major artery (VA ECMO).
The heart and lungs rest while doctors treat the underlying disease.
ECMO is started when all conventional treatment is failing to save a patient with severe lung failure, severe heart failure, or severe heart and lung failure. Results are better when ECMO is started before the kidneys, liver or other organs are affected, so early referral matters.
There are two main types of ECMO. Which one is used depends on whether the lungs alone, or the heart and lungs, need support.
| VV ECMO | VA ECMO | |
|---|---|---|
| Supports | Lungs only | Heart and lungs |
| Blood path | Vein → machine → vein | Vein → machine → artery |
| Role of the heart | Heart keeps pumping on its own | Machine bypasses heart and lungs temporarily |
| Typical conditions | Severe pneumonia, ARDS, poisoning, lung trauma, COVID-19 complications | Major heart attack, cardiac arrest, poisoning, severe heart failure |
| Complications | Fewer than VA ECMO | More than VV ECMO |
No. ECMO is not a cure. It gives the affected organ rest so it can heal while doctors treat the underlying disease. Just as a dialysis machine does the work of the kidneys, ECMO does the work of the lungs, the heart or both.
In suitable patients, ECMO can be delivered while the patient stays awake. Our team specialises in this approach. A patient on awake ECMO can:
This supports earlier recovery and discharge, and awake ECMO has shown better results than keeping patients sedated.

ECMO can be done safely only in hospitals that have:
Kauvery Hospital brings all of these together under one roof.
Yes, it is possible. ECMO can be started in any hospital, and the patient can then be moved to a hospital with the facilities above. Transfer can be done by road ambulance or air ambulance, within India and internationally.
The referring doctor calls our emergency line and shares the patient’s condition.
Our ECMO team reviews the case and advises on suitability for transfer.
Road or air ambulance transfer is arranged.
The patient is admitted to our cardiac ICU for continued ECMO care.
Call 044 4000 6000 (24/7).
Once the failing heart or lungs recover with appropriate treatment, ECMO can be removed. Depending on how well the heart or lungs recover, patients can usually return to their normal routine after a brief period of rehabilitation.
Bleeding and infection are the two main complications of ECMO. VV ECMO generally has fewer complications than VA ECMO. Because of these risks, patients on ECMO are monitored closely in the ICU by a team of specialists.
ECMO stands for extracorporeal membrane oxygenation. "Extracorporeal" means outside the body: the blood is oxygenated by a machine outside the body before it is returned.
A ventilator pushes air into the lungs and relies on the lungs to pass oxygen into the blood. ECMO adds oxygen to the blood outside the body, so severely damaged lungs (or a failing heart) can rest.
ECMO is started when conventional treatment is failing in a patient with severe lung failure, severe heart failure, or both. Results are better when it is started before the kidneys, liver or other organs are affected.
No. ECMO supports the heart and/or lungs so that they can rest and heal while doctors treat the underlying disease. It works much like a dialysis machine does for the kidneys.
VV (venovenous) ECMO supports the lungs only: blood is taken from a vein, oxygenated and returned to a vein. VA (venoarterial) ECMO supports both heart and lungs: blood is returned to a major artery. VV ECMO has fewer complications.
In suitable patients, ECMO is given while the patient stays awake and off the ventilator. Patients can talk to family, eat normally and do physiotherapy, which helps earlier discharge. Our team specialises in awake ECMO.
Bleeding and infection are the two main complications. Patients on ECMO are monitored closely in the ICU by a team of specialists.
It depends on how quickly the heart or lungs recover. Your ECMO team will explain what to expect for your condition.
Yes. ECMO can be started at any hospital and the patient can be transferred by road or air ambulance, nationally or internationally, to a hospital with a full ECMO setup.
An ECMO machine, a multidisciplinary team of doctors, round-the-clock perfusionists, trained nurses and physiotherapists, laboratory facilities and a blood bank.
Once the heart or lungs have recovered, ECMO is removed. Most patients return to their normal routine after a brief period of rehabilitation, depending on how well the organ has recovered.
The cost depends on the type of ECMO, how long support is needed, and the length of ICU stay. Please contact our team for an estimate, and see our Billing & Insurance page for payment and insurance help. Billing & Insurance
