Physiological variables like heart rate and respiratory rate are derived from waveform data. Collecting waveforms allows a more complex set of variables to be mathematically calculated including the rate pressure product (RPP), the Adjusted Pediatric Shock Index (SIPA) and the coronary perfusion pressure. In this study, we examine the behavior of these variables and ascertain whether they can be used to define compensated and decompensated states of heart failure in pediatric patients with biventricular circulations.
