Jayalalithaa's health: What is the ECMO device?
Tamil Nadu CM Jayalalithaa on Sunday suffered a cardiac arrest and has been put on Extracorporeal Membrane Oxygenation (ECMO), a heart device that helps cardiac and respiratory functions. The device drains blood from a vein, adds oxygen, removes carbon dioxide, and warms the blood before returning it to the artery. This enables the blood to bypass the lungs and heart.
