No reflow phenomenon is the failure of blood to reperfuse an ischemic area after the physical obstruction has been removed or bypassed.

Micro-bubbles can be used in many ways; they can be followed as they circulate in the bloodstream and then knocked out by a high-powered pulse and observed as they reperfuse the tissue.

I would say to you that you must have a defibrillator available should your patient reperfuse on the way to hospital and develop ventricular fibrillation, because having salvaged the myocardium, it is a shame to lose the patient and we cannot yet tell which patient will develop ventricular fibrillation and which will not.
