What is The Compensatory Reserve Index for Predicting Hemorrhagic Shock in Prehospital Trauma about?
## ABSTRACT ## Background The compensatory reserve index (CRI) is a noninvasive, continuous measure designed to detect intravascular volume loss. CRI is derived from the pulse oximetry waveform and reflects the proportion of physiologic reserve remaining before clinical hemodynamic decompensation. ## Methods In this prospective, observational, prehospital cohort study, we measured CRI in injured patients transported by Emergency Medical Services (EMS) to a single Level I trauma center. We determined whether the rolling average of CRI values over 60 seconds (CRI trend [CRI-T]) predicts in-hospital diagnosis of hemorrhagic shock, defined as blood product administration in the prehospital setting or within four hours of hospital arrival. We hypothesized that lower CRI-T values would be associated with an increased likelihood of hemorrhagic shock and better predict hemorrhagic shock than prehospital vital signs. ## Results Prehospital CRI was collected on 696 adult trauma patients, 21% of whom met our definition of hemorrhagic shock. The minimum CRI-T was 0.14 (Interquartile range (IQR) 0.08-0.31) in those with hemorrhagic shock and 0.31 (IQR 0.15-0.50) in those without (p = <0.0001).
