Extracorporeal Membrane Oxygenation (ECMO) Therapy in Mumbai, India
Overview
Extracorporeal membrane oxygenation, commonly known as ECMO, is an advanced life-support technique used in critical care when the heart or lungs are unable to function adequately despite conventional treatment. It temporarily supports the role of these organs by oxygenating the blood outside the body.
The system works by circulating blood through an external machine that removes carbon dioxide and adds oxygen before returning it to the patient. Depending on the type of ECMO used, it may support lung function, heart function, or both. ECMO does not treat the underlying disease but supports the body while the heart or lungs recover or while further treatment is planned.
Types of ECMO
Veno-Venous (VV) ECMO
Veno-venous ECMO is primarily used for patients with severe lung failure when the heart is still functioning adequately. Blood is drawn from a large vein, oxygenated outside the body, and returned to the venous system. This supports breathing while allowing the lungs to rest and recover.
Veno-Arterial (VA) ECMO
Veno-arterial ECMO is used when the heart needs circulatory support, with or without associated lung failure. Blood is removed from a vein, oxygenated, and returned directly into an artery, helping maintain blood circulation and oxygen delivery throughout the body.
Conditions Treated Under ECMO
ECMO is used in life-threatening conditions where conventional treatments are not sufficient to maintain oxygen levels or circulation. It acts as a temporary support system during severe organ failure.
Common conditions include:
- Severe respiratory failure
- Acute respiratory distress syndrome
- Severe heart failure or cardiogenic shock
- Cardiac arrest in selected cases
- Life-threatening infections affecting the lungs or heart
- Complications after major cardiac or lung surgery
- Severe trauma affecting breathing or circulation
ECMO provides critical time for the body to recover or for further medical interventions to be performed.
Preparation for ECMO Procedure
Pre-Procedure
Before starting ECMO, a detailed evaluation is carried out to determine whether the patient is suitable for the procedure. This stage helps the medical team plan safe and effective support.
Key steps include:
- Detailed patient assessment of heart and lung function
- Blood tests and imaging studies to evaluate organ status
- Discussion with family and obtaining informed consent whenever possible
During Procedure
The procedure involves connecting the patient to the ECMO machine through specialised tubes called cannulas. It is performed in an intensive care setting under strict monitoring.
Key steps include:
- Cannulation, where tubes are placed into major blood vessels
- Connection to the ECMO circuit for oxygenation and circulation support
- Continuous monitoring of vital signs, blood flow, oxygenation, and machine performance
After ECMO Support Begins
After ECMO support begins, the patient remains under close observation in the ICU. The focus is on stabilisation, recovery, and gradual improvement of heart or lung function.
Care includes:
- Gradual weaning from ECMO support when the condition improves
- Additional supportive treatments, such as ventilation, medications, or dialysis if required
- Continuous monitoring in the intensive care unit
Risks of ECMO
Although ECMO can be life-saving, it is a complex procedure that carries certain risks due to its invasive nature and the critical condition of patients.
Possible risks include:
- Bleeding due to blood-thinning medications
- Infection at cannulation sites
- Blood clot formation within the circuit
- Changes in blood pressure or circulation
- Kidney dysfunction or other organ-related complications during prolonged support
These risks are carefully managed through continuous monitoring and expert critical care supervision.
Complications of ECMO
Complications may occur depending on the patient’s underlying condition, duration of support, and response to treatment.
Possible complications include:
- Stroke or neurological events due to clot formation or bleeding
- Kidney dysfunction requiring additional support
- Reduced blood flow to limbs in rare cases, especially with VA ECMO
- Ongoing heart or lung dysfunction during the recovery phase
- Long-term weakness after prolonged ICU stay
Early detection and intensive monitoring help reduce the impact of these complications.

Frequently Asked Questions
1. What is ECMO used for?
ECMO is used to support patients with severe heart or lung failure when conventional treatments are not enough to maintain oxygen levels or circulation.
2. How long can a patient stay on ECMO?
Duration varies depending on recovery, ranging from a few days to several weeks, based on the underlying condition and response to treatment.
3. Is ECMO painful?
Patients are usually sedated, given pain relief, or closely monitored in intensive care, so discomfort is minimised during the procedure.
4. Are there alternatives to ECMO?
Alternatives may include mechanical ventilation, oxygen therapy, or medication-based support, but ECMO is used when these are not sufficient.
5. What are the survival rates for ECMO patients?
Outcomes depend on the severity of illness, underlying condition, age, organ function, and timing of treatment, making results highly individual.
6. Who runs the ECMO machine?
ECMO is managed by trained specialists, including perfusionists, ECMO specialists, and intensive care teams, under the supervision of critical care doctors.
