How to Describe Someone's Medical Condition Accurately to a 911 Dispatcher

Say what you see, hear and know, not what you think the diagnosis is. A short script that gives responders the facts they need.

General information, not medical advice. Reading a guide is not a substitute for a hands-on first aid or CPR class (American Red Cross, American Heart Association, and local fire-rescue departments offer them). If someone may be in danger, call 911 and follow the dispatcher.

A dispatcher cannot see the patient. They rely on your words to send the right help and to choose the right instructions. Accurate, plain facts beat medical guesses.

Describe, do not diagnose

Instead ofSay
“He's having a heart attack.”“He's 62, he has chest pressure, he's sweating and gray, and he's short of breath. It started 15 minutes ago.”
“She's diabetic and crashing.”“She is confused and sweaty. Her sister says she has diabetes and took insulin this morning.”
“I think it's a stroke.”“His face is drooping on the left, his speech is slurred, and he can't lift his right arm. It started at 2:10 pm.”
“She's dead.”“She's not responding and I don't see her breathing. I'm starting CPR as you tell me.”

The facts to have ready

Useful, measurable details

Numbers are better than adjectives. “She has taken about 8 breaths in the last 30 seconds” is more useful than “she's breathing weird.” If you have a pulse oximeter or thermometer, give the reading, but do not delay calling to find one.

If you are not sure

Say so: “I'm not sure if he's breathing.” The dispatcher will talk you through checking. Stay on the line, do what they say, and tell them right away if anything changes.
