Application of pattern recognition and image classification techniques to determine continuous cardiac output from the arterial pressure waveform Abstract: The shape of the arterial pressure waveform is a nonlinear function of stroke volume, heart rate and many other cardiovascular parameters.
Previous attempts have been made to exploit this relationship and derive cardiac output CO from the arterial pressure waveform. These classical "pulse-contour" methods utilized simplifying linear assumptions, as a result they failed to adequately estimate CO over a sufficiently wide range of hemodynamic conditions. The authors have applied pattern recognition and image professing techniques to the problem of deriving CO from the arterial pressure waveform, thereby eliminating the need for simplifying assumptions.
Pattern Recognition - Concepts, Methods And Applications
Computer simulations were used to develop the basic pattern recognition algorithms and compare their performance with that of published classical "pulse-contour" methods. Animal models were subsequently used to demonstrate proof of the concept.
