Abstract

BACKGROUND:

esCCO (estimated continuous cardiac output, Nihon Kohden, esCCO) is a new cardiac output measurement system which uses pulse wave transit time to calculate cardiac output continuously and non-invasively. One of the most commonly used methods to monitor cardiac output is continuous cardiac output CCO (Edwards Lifesciences) which has an accuracy equivalent to that of thermodilution method.

METHODS:

We compared esCCO to CCO in 67 operating room patients and 128 intensive care unit patients. CCO and esCCO were measured simultaneously in patients with a pulmonary artery catheter inserted after admission to the operating room or intensive care unit.

RESULTS:

CCO and esCCO showed a high correlation with a correlation coefficient of 0.84 in 496 total data points, and 95% limits of agreement between these two methods were -2.49 to 2.35 l x min(-1).

CONCLUSIONS:

This result suggests that esCCO could be used to measure cardiac output accurately and non-invasively in different cases.
