With ECMO, the survival rate can rise to 60 percent. During ECMO, the cannulae pump blood that is depleted of oxygen. The membrane oxygenator then puts oxygen into the blood.
Then it sends the oxygenated blood through the warmer and filter and returns it to the body. A doctor will check an individual before ECMO. A cardiac ultrasound will determine whether the heart is working. After determining that ECMO is necessary, doctors will prepare the equipment.
The team also includes:. Depending on your age, surgeons will place and secure the cannulae in the neck, groin, or chest while you are under general anesthesia. ECMO takes over the function of the heart or lungs. Medications will transfer continuously through intravenous catheters.
One important medication is heparin. This blood thinner prevents clotting as blood travels within the ECMO. You can stay on ECMO anywhere from three days to a month.
The longer you remain on ECMO, the higher the risk of complications. The biggest risk from ECMO is bleeding.
Heparin thins the blood to prevent clotting. It also increases risk of bleeding in the body and brain. ECMO patients must receive regular screening for bleeding problems. People on ECMO will likely receive frequent blood transfusions. These also carry a small risk of infection. Malfunction or failure of ECMO equipment is another risk.
Idiopathic pulmonary arterial hypertension is a lung disorder characterized by high blood pressure in the pulmonary artery. Overview In extracorporeal membrane oxygenation ECMO , blood is pumped outside of your body to a heart-lung machine that removes carbon dioxide and sends oxygen-filled blood back to tissues in the body.

Journal of Clinical Neurology. Mehta H, et al. Bartlett said his research team is working to make it so ECMO can be offered outside an ICU — and possibly even send patients home with a wearable device. Only the largest medical centers offer ECMO currently, and that has meant most hospitals in the South have been left waiting to transfer patients to a major medical center during the recent pandemic surge.
And the larger hospitals have their own covid patients eligible for ECMO who would be willing to try it. There is no formal process for prioritizing patients, though a national nonprofit has started a registry. ECMO is rarely used for anyone elderly or with health conditions that would keep them from seeing much benefit.
Even as big as Emory is, the Atlanta hospital is turning down multiple requests a day to transfer covid patients who need ECMO, Daneshmand said. And calls are coming in from all over the Southeast. Even for younger people, who tend to have better chances on ECMO, many are debilitated afterward.
Laura Lyons was a comedian with a day job in New York City before the pandemic. Though just 31 when she came down with covid, she nearly died. ECMO, she said, saved her life. But she may never be the same. She was in a northern Georgia community hospital, and the family searched for help at bigger hospitals — looking miles in every direction.
Yang left with a miracle. Plumlee and their children were left in mourning.
