Cardiac Output Measurements in Septic Patients: Comparing the Accuracy of USCOM to PiCCO

<table>Bland-Altmann plot of left-sided, aortal CO measurements by USCOM versus PiCCO. The mean bias was −0.36 l/min ± 0.99 with 95% limits of agreement from −2.34 to 1.62. The percentage error according to Critchley and Critchley was 29%.</table>
