Oxygen scavenging using acoustic droplet vaporization while altering droplet diameter and droplet concentration

Abstract

Transiently reducing the bioavailability of oxygen within an ischemic heart at the time of reperfusion may reduce the formation of reactive oxygen species and therefore reduce the amount of cell death. In vitro studies describe how the magnitude of oxygen scavenging changes as perfluorocarbon droplet diameter and droplet concentration are varied under ultrasonic exposure from an EkoSonic intravascular catheter.
