Measurement 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 کاملEndotracheal cardiac output monitor.
BACKGROUND The endotracheal cardiac output monitor (ECOM) is a new device that uses an endotracheal tube with multiple electrodes to measure cardiac output (CO). It measures the changes in electrical impedance caused by pulsatile blood flow in the aorta. The system was tested for safety and efficacy in 10 swine. METHODS Swine (60-80 kg) were chronically instrumented with a transit time flow p...
متن کاملEchocardiographic measurement of cardiac output in rats.
The systematic evaluation of different transthoracic echocardiographic (TTE) methods to determine cardiac output (CO) and the effect of changes in intravascular volume on echocardiographically determined indexes of cardiovascular structure in the rat has not been documented. With the use of 11 Wistar rats, simultaneous echocardiographic and thermodilution measurements of CO were compared at bas...
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 کاملReproducibility of linear cardiac output measurement by Doppler ultrasound alone.
Inclusion of a pig aorta in an artificial circulation with pulsed blood flow allowed correlation of minute distance, measured in the aorta by Doppler ultrasound, and absolute blood flow, measured by timed blood-volume collection. The correlation coefficient was 0.99 with a standard error of prediction that was 5.4% of the minute distance predicted at a standard flow rate of 5 litres per minute....
