Simultaneous measurement of cardiac output by thermodilution, thoracic electrical bioimpedance and Doppler ultrasound.
To evaluate the accuracy of two non-invasive techniques for cardiac output (CO) measurement, we have measured CO simultaneously by thoracic electrical bioimpedance (TEB), pulsed Doppler ultrasound (DU) and standard thermodilution methods (TD) under different clinical conditions. Measurements were made in 10 patients: (I) during steady state anaesthesia with controlled IPPV ventilation (n = 131)...
متن کاملNon-invasive determination of cardiac output by Doppler echocardiography and electrical bioimpedance.
Cardiac output measured by thermodilution in 25 patients within 24 hours of acute myocardial infarction was compared with cardiac output measured by Doppler echocardiography (24 patients) and electrical bioimpedance (25 patients). The mean (range) cardiac outputs measured by Doppler (4.03 (2.2-6.0) 1/min) and electrical bioimpedance (3.79 (1.1-6.2) 1/min) were similar to the mean thermodilution...
متن کاملCARDIOVASCULAR Monitoring non-invasive cardiac output and stroke volume during experimental human hypovolaemia and resuscitation
Key points † Controlled application of lower body negative pressure simulated hypovolaemia and resuscitation in human subjects. † Thoracic electrical bioimpedance, and arterial blood pressure (ABP) analysis by the Long Time Interval method, were the most discriminatory measurements. † The Modelflow method of ABP analysis effectively tracked hypovolaemia, but underestimated resuscitation. † Puls...
