Pulsed Doppler echocardiographic determination of stroke volume and cardiac output
Two methods of measuring stroke volume and cardiac output with pulsed Doppler twodimensional echocardiography were developed and validated against the thermodilution technique in 39 patients, 33 of which were in an intensive care unit. With the use of the apical four-chamber view, a mitral inflow method combined the velocity of left ventricular inflow at the mitral anulus with the crosssectiona...
متن کاملMeasuring cardiac output: intermittent bolus thermodilution method.
cialist in the cardiac care unit and cardiac observation unit at UCLA Medical Center and is an assistant professor of nursing at the UCLA School of Nursing, Los Angeles, Calif. by a computer and converted into a measurement of cardiac output. Cardiac output is inversely proportional to the area under the curve. The normal cardiac output curve has a rapid smooth upstroke and a gradual downstroke...
متن کامل[Comparison of cardiac output measurement in critical patients using transesophageal Doppler or thermodilution: a preliminary report].
BACKGROUND Cardiac output can be measured non invasively by transesophageal Doppler. This is an alternative to measure it by thermodilution with a catheter in the pulmonary artery. AIM To compare both methods of cardiac output measurement. MATERIAL AND METHODS Simultaneous measurement of cardiac output by transesophageal Doppler and thermodilution with a catheter in the pulmonary artery in ...
متن کاملTransoesophageal pulsed wave Doppler measurement of cardiac output during major vascular surgery: comparison with the thermodilution technique.
We measured cardiac output in 12 patients undergoing elective abdominal vascular surgery at specific times during the procedure with simultaneous thermodilution and transoesophageal pulsed Doppler echocardiographic techniques. No patient had clinical evidence of valvular heart disease before surgery. Five patients had echocardiographic evidence of mitral regurgitation on colour-coded Doppler. U...
متن کاملSimultaneous 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)...
