232: THE COMPENSATORY RESERVE INDEX IN CONGENITAL CARDIAC INTENSIVE CARE: PRELIMINARY DATA AND UTILITY.

B Learning Objectives: b The Compensatory Reserve Index (CRI) is a non-invasive technology that uses machine learning to analyze features of pulse waveforms on photoplethysmography. In adults, the CRI trends progression from baseline (CRI = 1) to hemodynamic instability (CRI = 0) more sensitively than changes in mean arterial pressure (MAP). In both T2 and T3, IC CRI remained at a 53% decline whereas RU CRI first nadired in T2 (-35%) then increased in T3 (-26%). [Extracted from the article]
