ECMO 101: Exploring Basic Concepts

Please note: exam questions are subject to change.

1. How has the history of ECMO shaped its primary function today? A dialysis machine that removes toxins from the blood A heart and lung bypass system that provides support while allowing organs to recover A ventilator that increases lung capacity through mechanical support A pacemaker that regulates heart rhythm in critically ill patients
2. All of the following are indications for ECMO support, EXCEPT? Mild hypoxic respiratory failure with PaO₂> 80 mmHg Oxygenation Index> 40 for 4 hours Failure to wean from 100% oxygen despite prolonged maximal medical therapy Severe pulmonary hypertension with right ventricular dysfunction
3. What is the primary difference between VA (Veno-Arterial) ECMO and VV (Veno-Venous) ECMO? VA-ECMO provides both cardiac and respiratory support, while VV-ECMO is limited to respiratory support VA-ECMO requires only a single venous access point, while VV-ECMO requires both venous and arterial access VV-ECMO supports only cardiac function, while VA-ECMO supports both heart and lungs VA-ECMO provides only respiratory support, while VV-ECMO provides both cardiac and respiratory support
4. What is the function of the ECMO oxygenator in the ECMO circuit? It propels blood forward using centrifugal force It regulates blood pressure by adjusting resistance It performs gas exchange by adding oxygen and removing carbon dioxide It prevents clot formation in the ECMO circuit
5. Which of the following is a common risk associated with ECMO therapy? Increased risk of arrhythmias Stroke due to blood flow compromise Development of chronic lung disease Hypothermia due to inadequate oxygenation
