First call:
While in the dining hall kitchen, a coworker (who was an off-duty EMT) dove for the bag valve mask stored in the wall mounted first aid kit right in front of me. "Call 911, 40 yo male, 250#, in the dining hall, dropped uncouncious, no pulse." As he's telling me this, the AED alarm goes off. I call 911, give them the details. As I'm giving them the details, a runner comes back to say that the patient was shocked, but no response...pass that on to 911 (call was placed roughly 30 seconds after he dropped, shocked roughly 1.5 minutes? after dropping). Hang up, and call the main camp office as protocol; it was a kids' camp with known false calls, so 911 checkes for veracity. It also starts the camp's emergency response. Unfortunatly, the secretary misunderstood "patient was shocked" for patient was "shot." Luckily the sheriff didn't roll (more on that later)
I check in with the responders, they're good - dash out to the groups on the field and tell our staff to do their stuff elsewhere. (5th graders and their teachers might react in interesting ways if they see an ambulance roll up). Hunt down the visiting group's lead teacher (on 150 acres), return with her to see ambulance driving away wiht the patient on board. About 15 minutes after I made the call and the patient dropped.
Notes: On a 450 acre camp, the patient dropped 30 feet away from an AED, in a building that an off-duty EMT was passing through. The patient was revived on the 2nd or 3rd shock, alert and oriented by the time the ambulance arrived, and was offering to get on the stretcher unassisted. Later report from the school was that there was minimal heart damage. :thumbsup:
About that whole sheriff thing...two days later the camp went into lockdown due to an armed bank robbery 2 miles away with the getaway car being found 0.25 miles away from a remote part of the camp. Nothing like telling kids "nothing to see here" while SWAT rolls around in full battle-rattle right outside the window :rolleyes: Later saw news images of the camp with SWAT sniper teams deployed on the property. Car was a decoy with one stolen a day earlier found 400 miles away.
It was a busy week!
Two other instances that I didn't call in:
1) Participant hyperventilates and passes out while in the harness on a climbing wall
2) Instructor has a brain anurism while on a climbing wall, group lowers him, and he was already unconcious with labored breathing. Dead before the ambulance arrived.
Rember folks...camp is a fun place!

Two minor calls:
1) After a T-storm, called in a sparking power line behind our property.
2) Called in large dangerous debris on a rather blind curve.
