This study aimed to develop and evaluate an algorithm for enriching the thermodilution signal. The method proposed presents an improvement of previous works in the literature in terms of precision, convergence and computational effort. The algorithm proposed is a deconvolution method that works without the need for precise knowledge of the transfer function of the temperature sensor in the Swan-Ganz catheter. In this method, the prior knowledge of the nature of the sensor response and a specific characteristic of the actual thermodilution signal is used, to estimate the response of the sensor, and then to determine a better estimate for the actual signal.
