| Popis: | Study ObjectivesTo compare the Nexfin cardiac output (CO) with the CO obtained from transthoracic Doppler echocardiography (TTE) during routine cardiac function screening.DesignObservational clinical study.SettingEchocardiography laboratory.Patients40 ASA physical status 1 and 2 patients scheduled for routine TTE examination.InterventionsNone.Measurements and Main ResultsIn 40 patients scheduled for routine TTE examination, we obtained simultaneous CO measurements with Doppler ultrasound and derived from Nexfin blood pressure measurements. Correlation and level of agreement between Nexfin and TTE were analyzed using Pearson correlation coefficient and Bland-Altman plots. The Pearson correlation coefficient for Nexfin versus TTE was 0.68 (CI: 0.46 - 0.82, P < 0.0001). Bland-Altman analysis showed a bias of 0.51 ± 1.1 L/min and limits of agreement of -1.6 to 2.6 L/min, with a percentage error of 39%.ConclusionsConsidering limits of precision of CO measurements with Doppler echocardiography (± 30%), the agreement between noninvasive CO measurement with the Nexfin and TTE is reasonable. |
