Temporal Statistical Relationship between Regional Cerebral Oxygen Saturation (rSO₂) and Brain Tissue Oxygen Tension (PbtO₂) in Moderate-to-Severe Traumatic Brain Injury: A Canadian High Resolution-TBI (CAHR-TBI) Cohort Study.

ABSTRACT: Brain tissue oxygen tension (PbtO₂) has emerged as a cerebral monitoring modality following traumatic brain injury (TBI). Near-infrared spectroscopy (NIRS)-based regional cerebral oxygen saturation (rSO₂) can non-invasively examine cerebral oxygen content and has the potential for high spatial resolution. Past studies examining the relationship between PbtO₂ and NIRS-based parameters have had conflicting results with varying degrees of correlation. Understanding this relationship will help guide multimodal monitoring practices and impact patient care. The aim of this study is to examine the relationship between PbtO₂ and rSO₂ in a cohort of TBI patients by leveraging contemporary statistical methods. A multi-institutional retrospective
