She was lucky. Don’t call the cops in such a situation. That was a big mistake. Call the medical first responders, if necessary.
Call 911 for medical help and the cops arrive for free.
It's good to think ahead of time about how you are going to seek help in various circumstances. Only ask for police if somebody needs to be violently subdued or shot, because that's what will likely happen if the cops show up. Also keep in mind that the 911 dispatcher is likely to not be very bright -- DO NOT utter "key words" that might make her conclude that violent response is needed.
If it's anything to do with an anxiety attack or other medical emergency, you need to just say to 911 "I need paramedics at [address], my XXX is in medical distress". This will put the dispatcher on her "medical" script, where she will ask you for symptoms, what medications he's on, .etc
“Dont call the cops in such a situation. That was a big mistake. Call the medical first responders, if necessary.”
The problem is, when you call 911 you not only get first responders, but also the cops. At least that’s what happens here in California. And if you cancel a 911 call, the cops show up en masse to “investigate.” I have had personal experience with this action.
Call 211, not 911.
