What is the priming volume for the CardioHelp system?

The priming volume for the CardioHelp system is 273 ml. Priming volume refers to the amount of fluid required to fill the ECMO circuit before it can be used in a patient. It is crucial to know the priming volume for proper calculation of hemodynamic status, ensuring there is adequate circulation without causing dilutional coagulopathy or volume overload.

In comparison, other volumes listed are either insufficient or excessive, potentially leading to complications. The accurate priming volume helps maintain appropriate fluid balance and also is significant for safely transitioning the patient onto ECMO, as it directly influences the initial assessment of venous return and cardiac output. Thus, knowing the specific priming volume for the CardioHelp system, which is 273 ml, is essential for any clinician working with this technology.
