Effect of prehospital advanced airway management on arterial blood gases in the pragmatic airway resuscitation trial.

ABSTRACT:

Background

Advanced airway devices facilitate ventilation and oxygenation during out-of-hospital cardiac arrest (OHCA). Differences in gas exchange between advanced airway devices are unknown.

Objective

Characterize arterial blood gases (ABG) in laryngeal tube (LT) or endotracheal intubation (ETI) cases in the Pragmatic Airway Resuscitation Trial (PART).

Methods

We included adult OHCAs with ABG collected ≤ 1.5 h after emergency department (ED) arrival. We collected 1) last prehospital airway technique used 2) ABG measurements (pH, PaO₂, PaCO₂), and 3) average prehospital end-tidal capnography (EtCO₂) values for the last five minutes. We compared airway types, ABG values, and PaCO₂-EtCO₂ absolute difference (PaCO
