Check, Call, Care.You check the scene to see if it's safe. Then you call for help (EMT or the emergency number) and then you provide care for the victim.
Specifically, CPR (lay person) is performing a set of 30 compressions & 2 breaths. The only concept that has three stages is going through the complete process from the scene through caring for the victim. These three steps are Check, Call, and Care. Check: Check the scene for safety and the person for consciousness. Call: Call 911 or the emergency number for your location. Care: Care for the conditions found.
Quickly check the pulse in her throat. If there is no pulse, then suspect a heart attack rather than choking. If she has a pulse, get help sitting the victim up and perform the Heimlich maneuver, 4 sharp pulls in a row. Repeat if nothing comes out.
You first check the scene is safe. Then you check the person. Then you call 911. Then put on protective barriers such as gloves if available. Then you treat.
