Elky, I stand corrected. He didn't have an ET tube, the medic placed an advanced airway though, and they delivered high-flow O2 with a bag-valve mask while the LUCAS did compressions on the way to the ED.

Since you're an expert, what do you think that effective CPR and ventilation did to Floyd's SaO2 level as they drove to the hospital?

You think it went up, or down?
