Know What to Do Until Help Arrives
Call 911.
If you're having a heart attack, chew one adult-strength aspirin (325 mg) or 2-4 low-dose aspirin (81 mg). EXCEPT if you cannot take aspirin due to allergies or other reasons.
If you see someone who is unconscious, and you know CPR, check for a pulse then apply your training. If you don't know CPR, ask the 911 operator to coach you.
