An NRB at 15 lpm as tolerated is probably your best bet, seriously. Ref. my above post, but oftentimes even in a non-code agitated patient, placing them on an NRB at 15 lpm while drawing up your sedative is severely lacking. This simple measure alone can do wonders to correct hypoxia, but again, I doubt in this case a sedative, or even DSI was indicated. Anytime a patient has no palpable pulse in a setting even with all the drugs, EBM, and trends in medicine, it typically means they're dying/ dead...in my experience.
