VV ECMO · Respiratory support
Venovenous ECMO drains blood from a vein and returns it to a vein. It supports gas exchange and relies on the patient's own circulation.

ECMO: a starting point for the extracorporeal support team
An English and Korean guide connecting ECMO fundamentals with educational tools and original references. For perfusionists, physicians, ICU nurses, respiratory therapists and learners.
What is ECMO?
Extracorporeal membrane oxygenation (ECMO) supports gas exchange outside the body. Blood passes through a circuit containing a pump and oxygenator before returning to the patient. It supports heart and/or lung function while the underlying condition is treated; it does not itself cure that condition.

VA ECMO · Circulatory support
Venoarterial ECMO drains blood from a vein and returns it to an artery, providing circulatory support as well as gas exchange.

Start with the task you need. Read each tool's formula, units, sources and review status before interpreting a result. Tools labelled as previews are not clinically validated.
Body surface area (BSA) →
Calculate BSA from height and weight and inspect the equation used.
ECMO duration →
Calculate elapsed minutes between a start and stop date and time.
Flow from BSA and cardiac index →
Explore BSA × a user-selected cardiac index. Educational arithmetic preview; it does not recommend an ECMO flow target.
Unit converter →
Convert measurement units, including French size and outer diameter. It does not determine cannula suitability.
