What criteria must be met for transport with mCPR if immediately available?

The criterion that focuses on witnessed arrest with ventricular fibrillation (VF) or ventricular tachycardia (VT) and reversible causes is essential for the use of mechanical cardiopulmonary resuscitation (mCPR) during transport. This option underscores the need for specific clinical situations where there is a high likelihood of a successful outcome if immediate advanced cardiac life support can be maintained.

In cases of witnessed cardiac arrest, especially when accompanied by VF or VT, the potential for successful defibrillation is highest, which is crucial for restoring effective heart function. The identification of reversible causes, such as hypoxia, hypovolemia, or electrolyte imbalances, further emphasizes the necessity of immediate intervention, as addressing these underlying issues can significantly improve the patient's chance of survival.

Thus, this criterion supports the rationale for utilizing mCPR during transport, ensuring that the patient's condition is stable enough to warrant continued advanced support while en route to definitive care.
