While attending this past weekend's Arnold Expo, my friend accidentally broke her arm at one of the booth events.
Although not a life-threatening emergency, I was extremely perturbed by the fact that none of the floor staff - even those with radios - could direct us to the paramedics.
We eventually got to the medical room outside the expo hall, but the nurse did not wish to receive the injured woman because she was not a registered competitor. Thankfully, there was a doctor there who did a quick assessment and applied a sling, and he then provided us with directions to a few local ERs.
Based on this experience, I shudder to think of what would've happened if someone had gone into cardiac arrest there. The event organizers should really take a hard look at this, because the current plan does not get the job done.
