Abstract

The primary goal of cardiopulmonary resuscitation (CPR) is to increase cardiac output (CO), providing adequate tissue perfusion and oxygenation to maintain normal organ function. A non-invasive, easy to use, commercially available esophageal doppler monitor (EDM, Deltex) has been found to provide minute distance (MD), which is the distance moved by a column of blood through the aorta in 1 min. The goal of our study was to determine if CO measurements correlate with the EDM MD, before and during cardiac arrest, in a porcine model of ventricular fibrillation. Twenty pigs were anesthetized and an EDM was placed. MD measurement using EDM, and CO measurement using florescent microsphere injections were compared before and during CPR. MD correlated well with CO (r2 = 0.96) before and during CPR. Based on the excellent correlation between MD as determined by EDM and CO by florescent microsphere technique, it appears that the non-invasive use of the EDM may play a valuable role in determination of CO during CPR.
