Ultrasonic Cardiac Output Monitor Provides Accurate Measurement of Cardiac Output in Recipients After Liver Transplantation

Endotracheal 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...

Ultrasonic Cardiac Output Measurement for Non- Invasive Cardiac Output Monitoring: Update and Lit- Erature Review

In this article, we review use and clinical utility of the Ultrasonic Cardiac Output Monitor, manufactured in Australia, which was first introduced clinically in 2001. It is non-invasive, requires only a low cost and allows for bedside examination, all of which make this tool potentially useful for patients in emergency departments and intensive care units. Its uses include triage, differential...

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...

Clinical evaluation of USCOM ultrasonic cardiac output monitor in cardiac surgical patients in intensive care unit.

BACKGROUND The USCOM ultrasonic cardiac output monitor (USCOM Pty Ltd, Coffs Harbour, NSW, Australia) is a non-invasive device that determines cardiac output by continuous-wave Doppler ultrasound. The aim of this study was to evaluate the accuracy of the USCOM device compared with the thermodilution technique in intensive care patients who had just undergone cardiac surgery. METHODS We conduc...

Is measurement of cardiac output using impedance cardiography accurate?
