ECMO Full Form: Extracorporeal Membrane Oxygenation

ECMO stands for "Extracorporeal Membrane Oxygenation." It is a medical treatment that involves using a machine to pump blood out of the patient's body, oxygenating it, and then returning it to the patient's body. The machine used for ECMO is called an ECMO machine or ECMO circuit. This is achieved by circulating the patient's blood through an artificial lung, which oxygenates the blood and removes carbon dioxide before returning it to the patient.

History of ECMO

ECMO was first developed in the 1970s as a way to provide oxygen to newborns with respiratory distress syndrome, a condition in which the lungs are unable to properly exchange gases. Over the years, the technology has been refined and expanded to include adult patients as well.

How ECMO Works

ECMO is a complex procedure that involves multiple components and specialized equipment. The basic components of an ECMO system include:

A blood pump that circulates the patient's blood through the circuit
An artificial lung, or oxygenator, that oxygenates the blood and removes carbon dioxide
A heat exchanger that warms or cools the blood to maintain the patient's body temperature
tubing and other equipment to connect the various components
The blood is withdrawn from the patient through a cannula (a small tube) inserted into a vein, typically in the neck or groin. The blood is then pumped through the artificial lung, where oxygen and carbon dioxide are exchanged. The oxygenated blood is then returned to the patient through another cannula, typically in the neck or groin.

Benefits of ECMO

ECMO has a number of benefits for patients. It can be used to support the circulation of blood and oxygen to the heart and lungs, and it can also be used to provide temporary support to the organs while they heal from an illness or injury. ECMO can also be used to provide support to the organs while they are recovering from surgery. Additionally, ECMO can be used to provide support to the organs while they are waiting for a transplant or while they are being treated with medications or other treatments.

Risks of ECMO

As with any medical procedure, there are risks associated with ECMO. These include bleeding, infection, clotting, and organ damage. Additionally, there is a risk that the patient may not respond to the ECMO treatment and may not survive the procedure.

Indications

ECMO is typically used as a last resort for patients with severe respiratory or cardiac failure that cannot be managed with conventional treatments. 

Common complications include:

• Acute respiratory distress syndrome (ARDS)
• Severe pneumonia
• Cardiogenic shock
• Decompensated heart failure
• Trauma
• Pulmonary embolism

Risks and Complications

ECMO is a highly invasive procedure that carries significant risks and potential complications. Some of the most common complications include:

• Hemorrhage or bleeding
• Infection
• Blood clots
• Arterial or venous cannula complications
• Acute kidney injury
• Neurological injury

Frequently Asked Questions - FAQs

What is the full form of ECMO ?

ECMO stands for Extracorporeal Membrane Oxygenation. ECMO is a form of advanced life support that is used to provide temporary life support to patients with severe heart and lung problems. It is a technique that uses a mechanical device to take over the function of the heart and lungs, allowing them to rest and heal.

How does ECMO work?

ECMO works by taking oxygen-rich blood from the body and oxygenating it outside of the body with a membrane oxygenator, which is a device that takes in blood and oxygenates it. The oxygenated blood is then returned to the body and circulated through the cardiovascular system. ECMO is typically used for patients who are in critical condition and whose heart and lungs can no longer function adequately on their own.

What is ECMO ventilator?

An ECMO ventilator, also known as an extracorporeal membrane oxygenation ventilator, is a specialized type of ventilator that is used in conjunction with ECMO, or extracorporeal membrane oxygenation, to provide both cardiac and respiratory support to patients whose hearts and lungs are unable to function adequately on their own. The ECMO ventilator is connected to the patient's lungs and oxygenates the blood outside the body, while the patient's own lungs are allowed to rest and heal.

The ECMO ventilator works by taking blood from the patient, oxygenating it outside the body, and then returning it to the patient. The ECMO ventilator uses a pump to circulate the blood through an oxygenator, which adds oxygen and removes carbon dioxide. The oxygenated blood is then returned to the patient through a cannula (a small tube) inserted into a vein.

The ECMO ventilator is used as a last resort for patients with severe respiratory or cardiac failure that cannot be managed with conventional treatments. It is a highly invasive procedure that carries significant risks and potential complications, and therefore, it should be used only when other treatments have failed or are not viable options.

It is important to note that ECMO is a complex procedure that requires specialized equipment, trained staff and close monitoring of the patient. This procedure should be carried out in a specialized center with experience in ECMO management.

Who needs ECMO?

ECMO, or extracorporeal membrane oxygenation, is typically used as a last resort for patients with severe respiratory or cardiac failure that cannot be managed with conventional treatments. Some of the conditions that may indicate the need for ECMO include:

Acute respiratory distress syndrome (ARDS): a severe lung condition in which the lungs become inflamed and fluid-filled, making it difficult to breathe.

Severe pneumonia: an infection of the lungs that can cause inflammation and fluid buildup, making it difficult to breathe.

Cardiogenic shock: a serious condition in which the heart is unable to pump enough blood to meet the body's needs.

Decompensated heart failure: a severe form of heart failure in which the heart is unable to pump enough blood to meet the body's needs.

Trauma: severe injuries, such as those from a car accident or a fall, can cause respiratory or cardiac failure.

Pulmonary embolism: a blockage of an artery in the lung that can cause respiratory failure.
Patients who are critically ill with respiratory or cardiac failure and are not responding to conventional treatments like mechanical ventilation and other forms of support may be considered for ECMO.

 The decision to use ECMO is made on a case-by-case basis and is based on the patient's specific condition, the availability of ECMO equipment and trained staff, and the patient's overall prognosis.

It is important to note that ECMO is a highly invasive procedure that carries significant risks and potential complications and therefore, it should be used only when other treatments have failed or are not viable options. The procedure should be carried out in a specialized center with experience in ECMO management.

How long can a person be on a ECMO machine?

The length of time a person can be on an ECMO machine can vary depending on the individual case and the underlying condition that led to the need for ECMO. In general, patients can be on ECMO for several days to several weeks.

• For patients with acute respiratory distress syndrome (ARDS), the average duration of ECMO treatment is 5 to 7 days, although some patients may be on ECMO for as long as 2 to 3 weeks. For patients with severe pneumonia or cardiogenic shock, the average duration of ECMO treatment is around 1 to 2 weeks.
• In some cases, patients may be on ECMO for a longer period of time if they are unable to be weaned off the ECMO support and require additional time for their lungs or heart to recover. In other cases, patients may be on ECMO for a shorter period of time if they respond quickly to treatment and are able to be weaned off ECMO support.

It is important to note that the duration of ECMO treatment will depend on the specific condition, the patient's response to the treatment, the availability of ECMO equipment and trained staff, and the patient's overall prognosis. The decision to continue or discontinue ECMO support is made on a case-by-case basis and is based on the patient's clinical status and the judgment of the treating physicians.

Can you recover from ECMO?

Recovery from ECMO, or extracorporeal membrane oxygenation, can vary depending on the individual case and the underlying condition that led to the need for ECMO. In general, many patients are able to recover and return to normal activity after ECMO treatment.

Patients with acute respiratory distress syndrome (ARDS), severe pneumonia, cardiogenic shock, or decompensated heart failure who receive ECMO treatment may experience significant improvement in their condition and are able to be weaned off ECMO support and return to normal activity.

It is important to note that recovery from ECMO also depends on the patient's overall health, the duration of ECMO treatment, and the individual patient's response to the treatment. Some patients may have underlying medical conditions that may impact their recovery, or may have suffered irreversible damage to their lungs or heart.

After ECMO treatment, patients may require additional medical support and rehabilitation to fully recover, such as physical therapy or respiratory therapy. Close monitoring and follow-up care are also important to ensure that any complications or issues are identified and addressed promptly.

In conclusion, while recovery from ECMO can be possible in many cases, it is a highly invasive procedure that carries significant risks and potential complications, it is not a guarantee for recovery. Therefore, it should be used only when other treatments have failed or are not viable options.

Is ECMO high risk?

ECMO, or extracorporeal membrane oxygenation, is a highly invasive procedure that carries significant risks and potential complications. Some of the risks associated with ECMO include:

Blood clots: blood can form clots in the ECMO circuit, which can travel to the brain, lungs, or other organs and cause serious damage.

Infection: because ECMO involves placing a tube in a vein or artery, there is a risk of infection at the insertion site or in the bloodstream.

Bleeding: ECMO can increase the risk of bleeding, particularly in patients who have underlying bleeding disorders or are taking blood-thinning medications.

Neurological complications: ECMO can cause neurological complications, such as seizures or changes in mental status, particularly in patients with underlying neurological conditions.

Multiple organ failure: ECMO can cause multiple organ failure, particularly in patients with underlying medical conditions that affect multiple organs.

Death: the procedure carries a risk of death, although the risk is generally considered to be low.

It's important to note that the risks associated with ECMO will depend on the individual case and the underlying condition that led to the need for ECMO. The decision to use ECMO is made on a case-by-case basis and is based on the patient's specific condition, the availability of ECMO equipment and trained staff, and the patient's overall prognosis.

ECMO is a highly specialized treatment and should only be used in specialized centers with experience in ECMO management. The procedure should be carried out by a team of highly trained and experienced healthcare professionals, including critical care specialists, cardiac surgeons, and perfusionists, who will closely monitor the patient and manage any complications that may arise.

Do people still breathe on ECMO?

When a person is on ECMO (extracorporeal membrane oxygenation), they are typically unable to breathe on their own and require mechanical ventilation to support their breathing. The ECMO machine is connected to the patient's bloodstream and provides oxygenation and sometimes also cardiac support.

• During ECMO, blood is drawn from the patient's body, typically from the right atrium of the heart or a large vein in the neck or leg, and is then pumped through an artificial lung, or oxygenator, where it is oxygenated before being returned to the patient's bloodstream. The ECMO machine also removes carbon dioxide from the patient's blood.
• While on ECMO, a patient's own lung function is typically maintained or supported by mechanical ventilation. The mechanical ventilation helps the patient to breathe and keep the lungs open, but the actual oxygenation is done by the ECMO machine.
• It is important to note that there are different types of ECMO, and the way they are applied depends on the patient's needs. Some are used to support only lung function, while others can also provide cardiac support.
• In conclusion, people on ECMO still breathe, but the ECMO machine takes over the oxygenation and carbon dioxide removal function of the lungs. The mechanical ventilation helps the patient to breathe and keep the lungs open, but the actual oxygenation is done by the ECMO machine.

How much does ECMO cost per day?

The cost of ECMO, or extracorporeal membrane oxygenation, can vary widely depending on a number of factors, including the type of ECMO used, the length of treatment, and the specific medical facility where the treatment is provided.

According to a 2015 report by the Healthcare Cost and Utilization Project (HCUP), the average cost for ECMO treatment in the United States was around $160,000 per patient. A more recent study from 2018, reported that the average cost per day for ECMO is around $20,000- $30,000 and the length of stay on ECMO was around 8 days.

It is important to note that these figures are averages and may not reflect the actual cost of ECMO treatment in all cases. Factors such as the patient's underlying medical conditions, the complexity of the ECMO treatment, and the specific medical facility where the treatment is provided can all affect the overall cost of ECMO.

Additionally, the cost of ECMO may also vary depending on the country and healthcare system, as well as the type of insurance coverage the patient has. Many insurance companies cover the cost of ECMO, but there may be limits on the amount of coverage or specific requirements that must be met before the treatment is approved.

In conclusion, the cost of ECMO treatment can vary widely, but on average it ranges between $20,000-$30,000 per day. It is important to consult with your healthcare provider and insurance company to understand the specific costs and coverage related to ECMO treatment.

Is the heart stopped during ECMO?

The heart is not typically stopped during ECMO (extracorporeal membrane oxygenation) treatment, but in some cases, the heart's function may be assisted by the ECMO machine.

There are two types of ECMO: veno-arterial (VA) ECMO and veno-venous (VV) ECMO

Veno-arterial (VA) ECMO: This type of ECMO is used to support both lung and heart function. Blood is removed from the patient's body, typically from the right atrium of the heart, and is then pumped through an artificial lung, or oxygenator, where it is oxygenated before being returned to the patient's bloodstream, typically through the aorta.

Veno-venous (VV) ECMO: This type of ECMO is used to support only lung function. Blood is removed from the patient's body, typically from a large vein in the neck or leg, and is then pumped through an artificial lung, or oxygenator, where it is oxygenated before being returned to the patient's bloodstream.

While on VA ECMO, the heart continues to beat and pump blood, but it may be assisted by the ECMO machine in cases where the heart is not able to pump enough blood. In VV ECMO, the heart continues to beat and pump blood as usual, but the ECMO machine takes over the oxygenation and carbon dioxide removal function of the lungs.

It's important to note that the ECMO procedure is usually only performed in critically ill patients with severe lung or heart failure, and the decision to use ECMO is made on a case-by-case basis and is based on the patient's specific condition, the availability of ECMO equipment and trained staff, and the patient's overall prognosis. ECMO is a highly specialized treatment and should only be used in specialized centers with experience in ECMO management and is carried out by a team of highly trained and experienced healthcare professionals.

What is the quality of life after ECMO?

The quality of life after ECMO (extracorporeal membrane oxygenation) treatment can vary widely depending on the patient's underlying medical condition, the length of time spent on ECMO, and the patient's overall health status before and after the treatment.

Some patients who receive ECMO treatment are able to make a full recovery and return to their normal activities and daily life. For example, patients with acute respiratory distress syndrome (ARDS) who receive ECMO treatment have been shown to have improved survival rates and better outcomes in terms of lung function, as compared to patients who did not receive ECMO treatment.

However, for some patients, the recovery process can be prolonged and may include physical therapy, rehabilitation, and other forms of follow-up care. Some patients may experience long-term complications, such as lung scarring or organ damage, which can affect their quality of life.

For critically ill patients who are receiving ECMO, the decision to use ECMO is made on a case-by-case basis and is based on the patient's specific condition, the availability of ECMO equipment and trained staff, and the patient's overall prognosis. ECMO is a highly specialized treatment and should only be used in specialized centers with experience in ECMO management and is carried out by a team of highly trained and experienced healthcare professionals.

It's important to note that the quality of life after ECMO will depend on the individual case, and if the patient has underlying diseases that may affect their quality of life even after a successful ECMO treatment, it's important for the patient and their family to have realistic expectations and prepare for the potential challenges.

Is ECMO permanent?

ECMO (extracorporeal membrane oxygenation) is not a permanent treatment. It is a temporary support system that is used to provide oxygen and/or cardiac support to critically ill patients whose lung or heart function is severely compromised. The goal of ECMO is to provide time for the patient's lungs or heart to heal or recover while they are on the machine.

The duration of ECMO treatment can vary widely depending on the patient's underlying medical condition, the patient's response to treatment, and the availability of other treatment options. For some patients, ECMO treatment may only be needed for a few days, while for others it may be needed for several weeks.

Once the patient's lung or heart function has improved to the point that they are able to breathe and pump blood on their own, the ECMO machine can be gradually weaned off, and the patient can be removed from the machine.

It's important to note that ECMO is a highly specialized treatment and should only be used in specialized centers with experience in ECMO management, and is carried out by a team of highly trained and experienced healthcare professionals. The decision to use ECMO is made on a case-by-case basis and is based on the patient's specific condition, the availability of ECMO equipment and trained staff, and the patient's overall prognosis.
