What is the priming volume for standard tubing used in ECMO systems?

• A. 15 ml
• B. 20 ml
• C. 25 ml
• D. 30 ml

Answer: (B)

The priming volume for standard tubing used in ECMO systems is typically around 20 ml. This priming volume is crucial because it helps ensure that the ECMO circuit is fully filled with fluid, allowing for an efficient and safe integration of the patient’s blood flow into the system. Adequate priming reduces the risks of air entering the circuit, which can lead to serious complications such as embolism. Understanding the significance of priming volume is essential for ECMO specialists, as it directly affects the hemodynamics and the functionality of the ECMO system. The standardization of this volume to 20 ml in many ECMO circuits strikes a balance between accommodating the blood flow requirements and minimizing the risk of dilution and other complications that could arise with higher or lower priming volumes.
