Ambulance personnel/paramedics very much do this, in Australia at least. They never run, never rush, and don't get sucked in to the panic and chaos.

US paramedic: Same here. If you have to run to a CPR to "save" that person, they're already dead. I had this argument with toxic bosses when I was an SRE - "If PagerDuty goes off I expect you to run to your computer, and have configured the escalations accordingly". No, boss, if I'm not running to a CPR, I'm not running to a "errors exceed 2% for XYZ API call". There's also the adage of "if you get injured, now we're…

You're a paramedic, so you have more training than I do. I was always taught CPR is a form of life support, and you have around three minutes from the time of arrest to begin CPR to prevent brain damage from hypoxia. So, why would seconds not matter for initiating CPR?

Perhaps this is because, as a paramedic on an ambulance, you're simply never on scene within three minutes? (As compared to a bystander)

So a couple of things, in order: every minute from arrest that no CPR is being done, chances of survival decrease by about 10%. If bystander compression-only CPR has been started, there's about 8 minutes supply of sufficiently oxygenated blood (and while compressions aren't ventilations, they do still encourage some small oxygen exchange). Even when we arrive, gaining advanced airway access or ventilation comes secondary to compressions (our county gives a limited window of 10-15 seconds to pause compressions to intubate, but with Glidescopes it's often possible to intubate through compressions).

- I'd be curious if the origin is really the Navy seals. I couldn't find in my brief searching any where else... - I like John Wooden's saying "be quick but don't hurry". I mentioned that to a doctor who trained in the mid 20th century and he said that surgeons had a line "hurry, but don't rush"

> surgeons had a line "hurry, but don't rush" One that came to my mind when I was trying to help my step-daughter learn to drive: "Be assertive, but don't be aggressive."

I told my child "Remember, they're all out to kill you."
