[The panic that sweeps over him is. a lot. He's paralyzed for a moment, unsure what to do first, before he's moving quickly to touch his jaw, tilting his head up and feeling for a pulse, ducking down near his mouth to see if he can feel that breath. When he's confirmed there's a pulse but no breath, that cold wave of dread really settles over him.]
Keith-- Please. [No, no, no--]
[This, at least, he knows how to do and now he doesn't hesitate-- getting Keith breathing is more important, but he needs to stop the breathing. He rips off his jacket and ties it around Keith's upper thigh to try to slow the blood, then moves to compress his hands down on his chest to get his lungs moving again, firmly, then opens Keith's mouth gently and ducking down to breathe into his mouth. He alternates a few times with that-- chest compressions and breathing, checking each time to see if Keith's breathing on his own yet. His hands are shaking as he moves, adrenaline and fear, eyes on Keith's face the entire time.]
