Latest Update 2026/2027 | Graded A+
Question 1
What does ECMO stand for?
A. Emergency Cardiac Monitoring Operation
B. Extracorporeal Membrane Oxygenation
C. External Cardiopulmonary Mechanical Oxygenation
D. Extracorporeal Circulatory Management Operation
Correct Answer: B. Extracorporeal Membrane Oxygenation
Explanation: ECMO is an advanced life-support technique that provides
prolonged cardiac and/or respiratory support by circulating blood outside the
body through an artificial lung (oxygenator) and returning oxygenated blood
to the patient.
Question 2
The primary function of the ECMO oxygenator is to:
A. Pump blood through the circuit
B. Remove carbon dioxide and add oxygen to blood
C. Monitor blood pressure
D. Prevent clot formation
Correct Answer: B. Remove carbon dioxide and add oxygen to blood
Explanation: The oxygenator functions as an artificial lung. It performs gas
exchange by adding oxygen and removing carbon dioxide from circulating
blood.

,Question 3
Which ECMO configuration primarily provides respiratory support?
A. VA ECMO
B. VV ECMO
C. VAV ECMO
D. Peripheral ECMO
Correct Answer: B. VV ECMO
Explanation: Veno-venous (VV) ECMO supports patients with severe
respiratory failure while maintaining native cardiac function.
Question 4
Which ECMO configuration provides both cardiac and respiratory support?
A. VV ECMO
B. VA ECMO
C. Venous ECMO
D. Oxygenator-only support
Correct Answer: B. VA ECMO
Explanation: Veno-arterial (VA) ECMO provides circulatory support by
returning oxygenated blood directly to the arterial system, assisting both
heart and lung function.
Question 5
In VV ECMO, blood is drained from:
A. An artery and returned to a vein
B. A vein and returned to a vein
C. An artery and returned to an artery
D. The pulmonary artery only
2|Page
,Correct Answer: B. A vein and returned to a vein
Explanation: VV ECMO uses venous drainage and venous return, allowing
oxygenation and carbon dioxide removal while the patient's heart continues
pumping blood.
Question 6
In VA ECMO, oxygenated blood is returned to the:
A. Venous system
B. Arterial system
C. Pulmonary vein only
D. Right atrium only
Correct Answer: B. Arterial system
Explanation: VA ECMO returns oxygenated blood into an artery, providing
direct circulatory support and improving systemic perfusion.
Question 7
The ECMO specialist is primarily responsible for:
A. Performing surgery independently
B. Managing and monitoring the ECMO circuit and patient support
C. Prescribing medications
D. Diagnosing all patient conditions
Correct Answer: B. Managing and monitoring the ECMO circuit and
patient support
Explanation: ECMO specialists operate and monitor the ECMO system, assess
circuit function, identify problems, perform troubleshooting, and collaborate
with the healthcare team.

, Question 8
Which component of the ECMO circuit removes blood from the patient?
A. Oxygenator
B. Drainage cannula
C. Heat exchanger
D. Blender
Correct Answer: B. Drainage cannula
Explanation: The drainage cannula removes deoxygenated blood from the
patient and directs it into the ECMO circuit.
Question 9
The main purpose of the ECMO pump is to:
A. Measure oxygen levels
B. Move blood through the circuit
C. Warm the patient
D. Prevent infection
Correct Answer: B. Move blood through the circuit
Explanation: The ECMO pump generates blood flow through the
extracorporeal circuit, allowing oxygenation and circulation support.
Question 10
Which parameter directly affects oxygen delivery during ECMO?
A. Blood flow rate
B. Patient height only
C. Room temperature
D. Medication schedule only
Correct Answer: A. Blood flow rate
