Σύγκριση νεότερων μη επεμβατικών με επεμβατικές τεχνικές μέτρησης της καρδιακής παροχής σε νοσηλευόμενους ασθενείς στη μονάδα εντατικής θεραπείας
Translated title:
Comparison of latest non-invasive with invasive technical measurements of cardiac outpout on nursing patients in the intensive care unit
Summary:
INTRODUCTION: The invasive measurement of cardiac output (CO) and its continuous monitoring presents both a technological and a clinical challenge, especially for the critically ill or patients in the intensive care unit (ICU).
AIM: The aim of this study was to apply and evaluate the use of a new automatic oscillatory cardiovascular device in patients in intensive care unit and to compare the estimated cardiac output values with the corresponding standard invasive cardiovascular function measurement.
The study was performed with the method of repeated successive in random order measurements of cardiac output, by thermo-dilation and the study device (mobil -o - graph), in 24 patients admitted to the ICU.
The reproducibility and accuracy of the device under investigation, was estimated by means of the Bland-Altman analysis, the ICC (intra class correlation coefficient) and the PE (percentage of error).
RESULTS: Mobil -O -Graph significantly underestimated cardiac output with a systematic error of -1.12±1.38 L/min.(p <0.01) compared to thermal dilution. However, the ICC was> 07, indicating a relative agreement between the device and the reference method, while the error rate was approximately 39%, which is considered to be within acceptable limits. Both measurements of cardiac output were repeatable by both Mobil-O-Graph (ICC = 0.73 and PE = 27.9%) and by thermal dilution (ICC = 0.91 and PE = 26.7%).
CONCLUSION: Our study demonstrated for the first time that the assessment of cardiac output to patients in ICU by a non-invasive, automatic oscillometer could be reproducible, demonstrating similar accuracy to the method of thermodilution. The accuracy of this device can be considered sufficiently acceptable.
