Extracorporeal Life Support Program (ECLS)
When your child’s heart or lungs are failing – and need more than medicine or mechanical ventilation – extracorporeal life support (ECLS) can take over long enough for them to heal, or until your child gets a transplant.
We provide all types of ECLS for children, including
- Extracorporeal membrane oxygenation (ECMO)
- Ventricular assist devices (VAD), including total artificial heart
Seattle Children's is the only hospital on the West Coast that can provide mobile ECMO for children who would normally be considered too fragile to be moved.
How do the different kinds of ECLS help?
Extracorporeal membrane oxygenation (ECMO)
ECMO is a form of heart-lung bypass used to pump oxygenated blood when your child’s heart or lungs fail to function properly or need to rest.
There are 2 types of ECMO:
- Venovenous ECMO. This type of ECMO does the work of your child’s lungs. Oxygen-poor blood is drawn through a tube (cannula) into a device that removes excess carbon dioxide and adds oxygen. The oxygen-rich blood is then returned to the body through another tube. Your child’s heart continues to pump blood to the body.
- Venoarterial ECMO. This type of ECMO does the work of your child’s heart and lungs. Oxygen-poor blood is drawn through a thin tube (cannula) into a device that removes excess carbon dioxide and adds oxygen. Then the device pumps the oxygen-rich blood into an artery in your child’s body. This type of ECMO can be used to completely support your child’s heart if it fails.
If your child needs CPR (cardiopulmonary resuscitation) because of cardiac arrest, we provide ECMO along with CPR. This approach, called extracorporeal CPR (ECPR), can help save a child’s life.
Our mobile ECMO service can bring critically ill children who are on an ECMO circuit to Seattle Children's from anywhere within the Alaska, Hawaii, Idaho, Montana, Oregon and Washington region.
- This highly skilled and coordinated team works in partnership with Airlift Northwest. The mobile ECMO team includes a cardiac surgeon, a cardiac intensivist, a perfusionist (ECMO specialist), an intensive care nurse and an Airlift NW flight nurse.
- Transport options include ambulance, helicopter or fixed-wing aircraft.
To request an ECMO transport evaluation, contact the Emergency Department Communication Center at 206-987-8899 or, toll-free, 866-987-8899.
Ventricular assist device (VAD)
A VAD is a mechanical heart pump that a surgeon can implant inside or outside your child’s chest to provide support for the heart as it recovers from injury or to help keep your child alive until heart transplantation.

What’s special about ECLS at Seattle Children’s?
- Seattle Children’s has the largest ECLS program for babies, children and teens in the Northwest. We provide all types of ECLS, including ECMO, VAD and total artificial heart. We are the only children's hospital on the West Coast to offer mobile ECMO.
- Our team of ECLS experts includes cardiopulmonary perfusionists, heart surgeons, general surgeons, intensivists, newborn specialists (neonatologists) and nurses or respiratory therapists with advanced ECMO training.
- Seattle Children’s Hospital has once again received the Award for Excellence in Life Support from the international Extracorporeal Life Support Organization. This award reflects Seattle Children’s commitment to patient safety and providing advanced, world-class care for our most critically ill patients.
- Surgeries for some high-risk conditions can be performed at Seattle Children’s only because we can use ECLS for a time after surgery to temporarily sustain heart function in children who would not be able to survive and recover without it.
- Our doctors conduct research to understand the factors that help children do better on ECLS. This research helps our team refine and improve treatment plans as we seek to better support patients and reduce complications. Seattle Children’s was recently selected as 1 of only 2 sites on the West Coast for the Pumps for Kids, Infants and Neonates (PumpKIN) trial. It will test a new mechanical heart-assist device for very young children and newborns. This research is sponsored by the National Heart, Lung and Blood Institute.
Who’s on the team?
Seattle Children’s ECMO nurses and respiratory therapists are specialists with advanced ECMO training. These specialists monitor a child’s ECMO pump 24 hours a day.
In 2013, Seattle Children’s started the Natalie Razore Rockstar ECMO Fellowship to provide advanced training for doctors working in this critical area of care.
