Performance of noninvasive partial CO2 rebreathing cardiac output and continuous thermodilution cardiac output in patients undergoing aortic reconstruction surgery.
BACKGROUND In the partial CO(2) rebreathing method, monitored changes in CO(2) elimination and end-tidal CO(2) in response to a brief rebreathing period are used to estimate cardiac output. However, dynamic changes in CO(2) production during ischemia and reperfusion may affect the accuracy of these estimates. This study was designed to compare measurements of cardiac output as produced by the p...
متن کاملEvaluation of a CO2 Partial Rebreathing-Based Functional Residual Capacity Measurement Method for Mechanically Ventilated Patients
There is a need for an automated bedside functional residual capacity (FRC) measurement method that can continually monitor both the size and a change in size of a patient’s lung volume during mechanical ventilation without the use of bulky equipment, expensive tracer gases or step increases in inspired oxygen fraction. We developed a CO2 rebreathing method for FRC measurement that simply requi...
متن کاملThe reliability of noninvasive cardiac output measurement using the inert gas rebreathing method in patients with advanced heart failure.
BACKGROUND Impaired cardiac output (CO) is a key element of heart failure (HF). So far, there has been no simple, reliable, inexpensive and non-invasive CO measurement method feasible for clinical practice. Not a single diagnostic test has been elaborated to diagnose and monitor HF. The aim of the study was the evaluation of the reliability of a new, non-invasive CO measurement device utilizing...
