Why the study?
Can cardiac output be accurately estimated noninvasively using adaptive aorta models and pulse contour waveforms compared to invasive methods?
Can cardiac output be accurately estimated noninvasively using adaptive aorta models and pulse contour waveforms compared to invasive methods?
A noninvasive method for estimating cardiac output using adaptive aorta models and pulse contour waveforms was developed and compared against invasive standards in dogs and patients.
Noninvasive cardiac output estimation via adaptive models lacks quantified validation; leaves open rigorous human trials before any clinical consideration.
A noninvasive method of measuring cardiac output is described. The method uses adaptive aorta models in conjunction with femoral and carotid pulse contour waveform measurements to calculate aortic flow. Results are presented from measurements on dogs using internal pressure recordings made with fluid-filled catheters and compared with electromagnetic flow measurements taken in the ascending aorta. Preliminary results using external pulse measurements on patients are also presented and compared with thermal dilution measurements.
