Abstract

To evaluate the correlation between cardiac output and EtCO2 in ICU patients. Methods: A cross-sectional descriptive study on 28 ICU patients, measuring EtCO2 and CI simultaneously for each patient at 5 time points, data was coded and processed according to statistical methods. Research results: The average values of CI and EtCO2 were 3.16 ± 0.59 and 33,84 ± 4,20, respectively. The mean value of CI in the low cardiac output group was 2.29 ± 0.17 which was statistically significantly lower than in the normal cardiac output group of 3.35 ± 0.46 with p=0,000. The mean value of EtCO2 in the low cardiac output group was 27.16 ± 2.12 which was statistically significantly lower than in the normal cardiac output group by 35.29 ± 2.94 with p = 0,003. Cardiac output and EtCO2 positively correlated with r=0.410 and p=0,000. In the low cardiac output group, CI and EtCO2 positively correlated with r=0,423 and p=0,007. Meanwhile, the correlation coefficient between CI and EtCO2 in the normal cardiac output group was 0.264 with p=0.004. Conclusion: Cardiac output and EtCO2 are positively correlated especially in the case of low cardiac output.
