|---|---|---|---|
1. Extracorporeal Membrane Oxygenation, colloquially referred to as “ECMO” or “artificial lung,” is a medical emergency device | 17 (8.46) | 104 (51.74) | 80 (39.80) |
2. ECMO is a form of cardiopulmonary life support that works by withdrawing venous blood from the body, oxygenating it, and then pumping it back into the patient's venous or arterial system, serving as a replacement for the heart and lungs | 13 (6.47) | 72 (35.82) | 116 (57.71) |
3. ECMO can be used for various reasons leading to cardiac or respiratory arrest, severe cardiac failure, severe respiratory failure, and various conditions that critically threaten respiratory and circulatory function, such as severe asthma, drowning, etc | 14 (6.97) | 71 (35.32) | 116 (57.71) |
4. ECMO can temporarily replace a patient's cardiopulmonary function, alleviating the burden on the patient's heart and lungs, in situations such as respiratory failure, cardiac arrest, etc | 19 (9.45) | 66 (32.84) | 116 (57.71) |
5. ECMO, as an effective adjunct for diseased hearts, can buy valuable time for further diagnosis and treatment of the heart | 20 (9.95) | 74 (36.82) | 107 (53.23) |
6. Whether it is a cardiac or respiratory disease, not all cases require VA (venous to arterial) | 9 (4.48) | 49 (24.38) | 143 (71.14) |
7. Internationally, ECMO can also be used in infants when necessary, and its effectiveness in infants is superior to that in adults | 9 (4.48) | 49 (24.38) | 143 (71.14) |
8. Complications of ECMO include bleeding, infection, central nervous system complications, thrombosis, and more | 14 (6.97) | 74 (36.82) | 113 (56.22) |
9. Due to ECMO punctures and catheter placement, local vascular damage may occur, resulting in long-term narrowing of blood vessels, possibly requiring subsequent vascular dilation procedures | 10 (4.98) | 52 (25.87) | 139 (69.15) |
