Prognostic value of early point-of-care blood gas analysis in critically ill non-trauma patients

Background

Critically ill non-trauma patients treated in the emergency department have a high risk of in-hospital mortality. While point-of-care diagnostics such as blood gas analysis are established tools for urgent management, data on their prognostic value in this specific patient cohort remain limited. This study aimed to evaluate whether initial blood gas parameters are independently associated with in-hospital mortality in critically ill non-trauma patients.
