Expiratory ventilation assistance versus pressure-controlled ventilation with ambient oxygen in a hemorrhagic trauma model: a prehospital rescue option?

Both EVA and PCV effectively maintained oxygen delivery and sufficient oxygenation after trauma hemorrhage and whole blood resuscitation. Lower intratracheal pressures and reduced lactate accumulation with EVA suggest it may be a viable prehospital rescue method, especially in scenarios with limited oxygen supply. Further investigation is warranted to optimize its application.
