SYNOPSIS: A multicenter, prospective, nonrandomized study was performed to evaluate a new continuous cardiac output monitoring system and compare it with the currently used method, intermittent injection thermodilution. Forty-seven critically ill adult patients had cardiac output monitored over a 72-hour period simultaneously with both methods. In this study, the continuous cardiac monitoring system turned out to be a reliable method that was not adversely affected by abnormal patient temperature (<37°C or >38°C), high (>7.5 L/min) or low (<44.5 L/min) cardiac output, or duration (72 hours) of the study.
