Questions About ECMO
How do you pronounce ECMO?

What does ECMO stand for?

ECMO is an abbreviation that stands for "Extracorporeal Membrane Oxygenation." When you see the letters E-C-M-O written out, you simply say them as one word: "EK-moh" rather than spelling each letter separately.
What does 'extracorporeal' mean in ECMO?
+
"Extracorporeal" comes from Latin and means "outside the body." The prefix "extra-" means outside, and "corporeal" refers to the body. So when you hear ECMO, part of the name is telling you that this involves blood going outside the body.
How do you break ECMO into syllables?

What's the most common mispronunciation of ECMO?

Many people accidentally stress the second syllable and say "ek-MOH," but the correct way puts the emphasis on the first syllable: "EK-moh." Think of the word "echo" to remember the stress pattern.
In plain English, what does ECMO do?
+
ECMO is a life support machine that does the job of the heart and lungs by taking blood out of the body, adding oxygen to it, removing waste, and putting the cleaned blood back. It's like giving those organs a break when they need help.
What is a related word that shares a root with ECMO?
+
The word "membrane" is related to ECMO because it shares part of the full term—ECMO uses a special membrane to filter the blood. Both words come from Latin and refer to thin, flexible layers or barriers.
How would you use ECMO correctly in a sentence?
+
You might hear someone say, "The hospital set up ECMO support for the patient," or "Doctors decided to use ECMO as a temporary measure." In both cases, you're using the word to name the type of medical equipment or support being used.
