When the heart or lungs become severely impaired, conventional treatments may sometimes be insufficient to maintain adequate oxygen delivery or circulation. In selected critically ill patients, doctors may consider extracorporeal membrane oxygenation (ECMO), an advanced form of temporary life support.

ECMO uses a machine to circulate blood outside the body through an artificial membrane that adds oxygen and removes carbon dioxide. Depending on the type of ECMO used, the system can provide support primarily for the lungs or for both the heart and lungs.

ECMO is not a treatment for every type of heart or lung problem. It is a complex therapy used only in carefully selected situations by specialised critical-care teams. The decision depends on the underlying disease, severity of organ failure, response to other treatments, overall health and whether there is a realistic treatment pathway for recovery or another appropriate next step.

The Kurnool hospital information published by SirisHealthcare lists ECMO support among the advanced medical technology available at Medicover Hospitals, Sampath Nagar, Kurnool. The hospital also lists critical care, emergency medicine, cardiology, pulmonology and other specialties relevant to the management of complex illness.

What Is ECMO?

ECMO stands for extracorporeal membrane oxygenation.

The term can be understood in three parts:

• Extracorporeal means outside the body.
• Membrane refers to the artificial membrane that performs gas exchange.
• Oxygenation means adding oxygen to the blood.

During ECMO, blood is withdrawn from the body through large tubes called cannulas. It passes through an oxygenator, where oxygen is added and carbon dioxide is removed. The blood is then returned to the body.

In simple terms, ECMO can temporarily take over some of the work normally performed by the lungs and, with certain configurations, the heart.

It is important to understand that ECMO does not automatically cure the condition that caused organ failure. Instead, it can provide temporary support while doctors treat the underlying problem or determine the next appropriate step.

When Is ECMO Used?

ECMO may be considered when severe heart or lung dysfunction prevents the body from receiving adequate oxygen or maintaining sufficient circulation despite other appropriate treatments.

Examples can include selected cases of:

• Severe respiratory failure
• Acute respiratory distress syndrome (ARDS)
• Severe lung injury
• Certain forms of severe heart failure
• Cardiogenic shock
• Some severe cardiac emergencies
• Selected cases of pulmonary embolism
• Certain situations involving heart or lung surgery or transplantation

The exact indications vary between patients and ECMO centres. Doctors need to consider whether ECMO is likely to provide a meaningful bridge to recovery, another treatment, transplantation or another clinically appropriate goal.

For patients with serious breathing problems, Pulmonology care at Medicover Hospitals, Kurnool can be relevant because the hospital's published pulmonology information covers respiratory failure, severe respiratory conditions and interventional pulmonary procedures including bronchoscopy.

For patients with severe cardiovascular problems, the hospital's Cardiology department provides cardiac evaluation and lists catheter-based cardiac services among its capabilities.

What Are the Main Types of ECMO?

There are two major ECMO configurations: VV-ECMO and VA-ECMO.

VV-ECMO: Primarily Supports the Lungs

Veno-venous ECMO (VV-ECMO) is generally used when the lungs are failing but the heart is still able to circulate blood adequately.

Blood is taken from a vein, passed through the ECMO circuit for oxygenation and carbon-dioxide removal, and returned to the venous circulation. The heart continues pumping the oxygenated blood through the body.

VV-ECMO may be considered in selected patients with severe respiratory failure when conventional respiratory support is not sufficient and the medical team believes the lungs may recover or another appropriate treatment pathway exists.

VA-ECMO: Supports the Heart and Lungs

Veno-arterial ECMO (VA-ECMO) provides both circulatory and respiratory support.

In this configuration, blood is removed from a vein, passes through the ECMO circuit and is returned to an artery. This allows the system to provide support when the heart is unable to pump enough blood to meet the body's needs.

VA-ECMO may be considered in selected situations involving severe cardiac dysfunction, such as certain cases of cardiogenic shock or other serious cardiac emergencies.

The choice between VV-ECMO and VA-ECMO is a specialised clinical decision. It is not something a patient can determine based on symptoms alone.

How Does ECMO Work?

The ECMO circuit generally includes several important components:

1. Cannulas

Large tubes, called cannulas, are inserted into major blood vessels. Their position and configuration depend on the type of ECMO being used.

2. Pump

The pump moves blood from the patient's circulation through the ECMO circuit.

3. Oxygenator

The oxygenator functions like an artificial lung. It adds oxygen to the blood and removes carbon dioxide.

4. Tubing

Specialised tubing connects the patient's blood vessels to the ECMO circuit.

5. Monitoring System

The ECMO team continuously monitors the circuit and the patient's physiological condition to determine whether support needs to be adjusted.

Because ECMO involves major blood vessels, continuous monitoring and specialised clinical management are essential.

ECMO and Mechanical Ventilation: What Is the Difference?

A ventilator and ECMO perform different functions.

A mechanical ventilator helps move air into and out of the lungs. It can support breathing when a patient cannot breathe adequately on their own.

ECMO, in contrast, circulates blood through an external oxygenator to add oxygen and remove carbon dioxide. In severe respiratory failure, ECMO can provide additional support when conventional ventilation and other treatments are not enough.

A patient receiving ECMO may still require mechanical ventilation. In some situations, ECMO can allow the clinical team to reduce the intensity of ventilator support while the lungs are being treated.

The decision depends on the patient's condition and the strategy chosen by the critical-care team.

What Conditions May Lead Doctors to Consider ECMO?

ECMO is generally considered in highly selected cases rather than routine treatment.

Severe Respiratory Failure

Severe respiratory failure occurs when the lungs cannot provide sufficient oxygen or remove enough carbon dioxide.

Possible causes include severe pneumonia, ARDS and other serious lung injuries. ECMO may sometimes be considered when conventional respiratory support is inadequate.

Acute Respiratory Distress Syndrome

ARDS can cause extensive lung inflammation and impaired oxygen exchange. In severe cases, a patient may require mechanical ventilation and other intensive treatments. ECMO may be considered in selected cases when appropriate criteria are met.

Cardiogenic Shock

Cardiogenic shock occurs when the heart cannot pump enough blood to meet the body's needs.

In carefully selected patients, VA-ECMO may provide temporary circulatory support while the medical team treats the underlying cause or determines the next treatment strategy.

Severe Cardiac Emergencies

Certain serious cardiac conditions may result in profound circulatory instability. ECMO can sometimes be considered as temporary support in specialised circumstances.

Selected Pulmonary Embolism Cases

A severe pulmonary embolism can place significant stress on the heart and impair circulation. In selected patients with severe cardiovascular instability, VA-ECMO may form part of advanced support.

However, ECMO is not automatically required for pulmonary embolism. The treatment approach depends on the patient's clinical condition and available options.

How Do Doctors Decide Whether ECMO Is Appropriate?

ECMO is not prescribed simply because a patient is very sick.

A specialised team may consider several factors, including:

• What caused the heart or lung failure?
• How severe is the organ dysfunction?
• Has the patient responded to appropriate conventional treatment?
• Is the underlying condition potentially reversible?
• Is there a possible pathway toward recovery?
• Would ECMO provide a bridge to another appropriate treatment?
• What other medical conditions does the patient have?
• What are the potential risks of ECMO?
• What level of organ support is required?
• Is the required ECMO configuration available?

The decision requires balancing potential benefits against substantial risks.

ECMO centres generally use specialised multidisciplinary teams to assess whether a patient is an appropriate candidate.

What Happens Before ECMO Is Started?

When ECMO is being considered, the medical team first evaluates the patient's condition.

Assessment may include:

Medical History

Doctors review existing diseases, previous procedures, medicines, allergies and the circumstances that caused the current deterioration.

Physical and Clinical Assessment

The team evaluates breathing, circulation, neurological status, blood pressure, oxygen levels and other vital parameters.

Laboratory Testing

Blood tests may be used to evaluate oxygenation, carbon dioxide levels, kidney function, blood counts, electrolytes and other important factors.

Imaging and Cardiac Tests

Depending on the suspected cause, doctors may use imaging and cardiac investigations to understand what is happening.

Response to Previous Treatment

The team also considers how the patient has responded to treatments such as oxygen therapy, mechanical ventilation, medicines or other interventions.

This assessment helps determine whether ECMO is appropriate and which type of support may be required.

What Are the Risks of ECMO?

ECMO can provide important temporary support, but it is an invasive treatment with significant risks.

Potential complications include:

• Bleeding
• Blood clots
• Infection
• Stroke
• Blood-vessel complications
• Problems involving the ECMO circuit
• Changes in blood oxygen levels
• Complications associated with cannulation
• Other complications related to prolonged critical illness

Blood-thinning medication is commonly used during ECMO because blood contact with the artificial circuit can increase the risk of clot formation. This can also increase bleeding risk.

The risks vary depending on the patient's condition, ECMO configuration, duration of support and other clinical factors.

How Long Does ECMO Continue?

There is no universal ECMO duration.

Some patients may require support for hours or days, while others may need it for longer periods. The duration depends on the underlying disease, response to treatment, organ recovery and the treatment pathway being pursued.

The goal is generally to reduce ECMO support when the patient's heart or lungs have recovered sufficiently or when another appropriate treatment pathway has been established.

What Happens When a Patient Is Ready to Come Off ECMO?

The process of reducing ECMO support is known as weaning.

The clinical team assesses whether the patient's heart and/or lungs can function adequately with less ECMO assistance.

The process may involve:

1. Monitoring organ function.
2. Reducing ECMO support gradually.
3. Assessing oxygenation and circulation.
4. Checking whether the patient can maintain adequate function without full ECMO assistance.
5. Removing the ECMO cannulas when the medical team determines that continued support is no longer required.

The exact process depends on whether the patient was receiving VV-ECMO or VA-ECMO and on the reason ECMO was initiated.

What Role Does Critical Care Play During ECMO?

ECMO is closely connected to intensive care because patients requiring it are critically ill.

A critical-care team may monitor:

• Oxygen levels
• Carbon dioxide levels
• Blood pressure
• Heart rhythm
• Kidney function
• Neurological status
• Fluid balance
• Blood tests
• Signs of infection
• Bleeding or clotting
• ECMO circuit function

The Critical Care department at Medicover Hospitals, Kurnool describes intensive monitoring, respiratory support, cardiovascular support, organ support, management of severe infections and postoperative critical care among its areas of care.

The hospital page also lists ECMO support and modern intensive-care facilities among its advanced medical technology and infrastructure.

Because ECMO patients can have problems involving multiple organs, critical care may involve coordination with cardiology, pulmonology, neurology, nephrology, surgery and other specialties depending on the patient's condition.

For example, the hospital's Nephrology service covers kidney-related care and renal replacement therapies, while its Neurology service provides neurological evaluation and management.

ECMO Support at Medicover Hospitals, Sampath Nagar, Kurnool

SirisHealthcare's current hospital information identifies ECMO support as one of the advanced technologies listed for Medicover Hospitals, Sampath Nagar, Kurnool. The same hospital page lists critical care, cardiology, pulmonology, emergency medicine and several other specialties.

This information can be useful for patients and families researching hospitals that provide advanced critical-care capabilities.

However, the presence of ECMO support does not mean that every patient with respiratory or cardiac failure will require ECMO or that ECMO will necessarily be appropriate for a particular patient.

Suitability depends on a detailed medical assessment.

Patients and families should confirm the current availability of ECMO, the type of ECMO support offered, specialist availability and the clinical pathway for an individual case directly with the hospital before making treatment or travel arrangements.

For planned specialist care, the hospital's doctor directory allows patients to review currently listed specialists and departments.

When Should a Patient Seek Emergency Care?

ECMO is an advanced critical-care intervention, not a reason to delay emergency treatment while researching hospitals.

A person experiencing severe or rapidly worsening symptoms such as:

• Severe difficulty breathing
• Blue or grey discoloration of the lips or skin
• Loss of consciousness
• Severe chest discomfort
• Sudden collapse
• Severe confusion
• Very low blood pressure
• Serious trauma
• Severe respiratory distress

may require immediate emergency medical assessment.

Medicover Hospitals, Kurnool lists 24/7 emergency and trauma care.

The hospital's Emergency Medicine service describes rapid assessment, stabilisation, airway and breathing support, cardiovascular management and coordination with critical care and other specialties when required.

For a life-threatening emergency, seek emergency medical care immediately rather than waiting for a routine appointment or online consultation.

Questions to Ask the Medical Team About ECMO

If ECMO has been discussed for a family member, it can be difficult to understand the situation quickly. Useful questions may include:

• Why is ECMO being considered?
• What caused the heart or lung failure?
• Is the proposed support VV-ECMO or VA-ECMO?
• What problem is ECMO expected to support?
• What other treatments have already been tried?
• Is the underlying condition potentially reversible?
• What are the major risks in this individual case?
• What other specialists are involved?
• What signs would indicate improvement?
• How will the team assess readiness for weaning?
• What care may be needed after ECMO?

Families should ask the treating team to explain unfamiliar terms and treatment decisions in language they can understand.

If You Are Researching ECMO Treatment in India

Patients travelling from another city or country for complex medical treatment may need more than information about the technology itself.

Before planning treatment, it can be useful to organise:

• Previous hospital discharge summaries
• CT or MRI reports
• Laboratory reports
• Cardiac investigation results
• Current medication list
• Allergy information
• Previous treatment records
• Relevant ICU or ventilator records
• Information about the underlying diagnosis

For international patients, sending available medical records for specialist review before travel may help the treating team understand the case and determine what additional information is required.

The hospital's current FAQ and patient information page provides information about specialties, appointments, emergency services, diagnostic facilities and critical care at the Kurnool hospital.

The Bottom Line

ECMO is a form of temporary advanced life support that can take over some of the functions of the lungs and, depending on the configuration, the heart.

It may be considered in carefully selected patients with severe respiratory or cardiovascular failure when conventional treatment is not sufficient and there is an appropriate clinical reason to provide extracorporeal support.

The two main configurations are:

• VV-ECMO, primarily supporting the lungs
• VA-ECMO, supporting both circulation and the lungs

ECMO is complex and carries significant risks, including bleeding, clotting and infection. The decision to use it requires specialist assessment and careful consideration of the patient's underlying condition, potential for recovery and overall treatment goals.

SirisHealthcare currently lists ECMO support at Medicover Hospitals, Sampath Nagar, Kurnool, alongside critical care, emergency medicine, cardiology, pulmonology and other multidisciplinary services.

If ECMO has been recommended for you or a family member, discuss the indication, expected goals, risks, alternatives and treatment plan directly with the specialist team caring for the patient.
FAQs

What is ECMO in critical care?

ECMO, or extracorporeal membrane oxygenation, is temporary life support that circulates blood through an external oxygenator to add oxygen and remove carbon dioxide. Depending on the configuration, it can support the lungs alone or both the heart and lungs.

When is ECMO used?

ECMO may be considered for selected patients with severe respiratory or cardiovascular failure when conventional treatment is insufficient. The underlying cause, severity of illness, response to treatment and possibility of recovery all influence the decision.

What is the difference between VV-ECMO and VA-ECMO?

VV-ECMO primarily provides lung support. VA-ECMO can provide both cardiac and respiratory support. The appropriate configuration depends on which organs are failing and the patient's clinical condition.

Is ECMO the same as a ventilator?

No. A ventilator supports breathing by moving air into and out of the lungs. ECMO circulates blood through an external oxygenator that adds oxygen and removes carbon dioxide. A patient may require both forms of support.

What are the risks of ECMO?

Potential complications include bleeding, blood clots, infection, stroke and complications associated with cannulas or the ECMO circuit. The risks depend on the patient's condition and the type and duration of ECMO support.

How long does ECMO treatment last?

There is no standard duration. ECMO may be required for hours, days or longer depending on the underlying condition, organ recovery and treatment strategy.

Does Medicover Hospitals, Kurnool provide ECMO support?

The SirisHealthcare hospital page for Medicover Hospitals, Sampath Nagar, Kurnool currently lists ECMO support among its advanced medical technology and critical-care capabilities.
