Fiberoptic-Dye Dilution Method for Measurement of Cardiac Output
A new method for the measurement of cardiac output has been tested in 69 patients undergoing catheterization of the right and left sides of the heart. It is based on the recently described fiberoptic hemoreflection method. In order to verify the validity of these measurements, correlations with stroke indices determined by the Fick principle and by biplane angiocardiography were also carried ou...
متن کاملMeasurement of cardiac output.
Float catheterisation of the pulmonary artery was described in The Lancet by Dr R D Bradley (as he then was) in 1964 at a time when invasive circulatory monitoring was almost non-existent outside cardiac surgical units, and ‘intensive care’ was a term barely in use. Cardiac catheterisation was laboratory based and required radiological control: management of acute circulatory crises relied on c...
متن کاملContinuous cardiac output measurement: pulse contour analysis vs thermodilution technique in cardiac surgical patients.
We have analysed the clinical agreement between two methods of continuous cardiac output measurement pulse contour analysis (PCCO) and a continuous thermodilution technique (CCO), were both compared with the intermittent bolus thermodilution technique (BCO). Measurements were performed in 26 cardiac surgical patients (groups 1 and 2, 13 patients each, with an ejection fraction > 45% and < 45%, ...
متن کاملAnesthesia Issues in Cardiac Surgery
The principle of anaesthesia for open-heart surgery is based on simplicity, safty and lightplane of anaesthesia. As a result of the special pathophysiology, grave general status, complications threatening these patients during and after the operation and the abundance of medicines available nowadays, it is very important for the anaesthetist to be acquainted with the pathophysiological and ph...
متن کاملAccuracy of Cardiac Output by Nine Different Pulse Contour Algorithms in Cardiac Surgery Patients: A Comparison with Transpulmonary Thermodilution
Objective. Today, there exist several different pulse contour algorithms for calculation of cardiac output (CO). The aim of the present study was to compare the accuracy of nine different pulse contour algorithms with transpulmonary thermodilution before and after cardiopulmonary bypass (CPB). Methods. Thirty patients scheduled for elective coronary surgery were studied before and after CPB. A ...
