Would you know what to do if someone suddenly collapsed and stopped breathing normally?
When cardiac arrest happens, every second counts. Yet, only about half of Americans say they would feel confident performing CPR in an emergency.
In the latest installment of UTHealth Houston's Ask the Expert series, Kevin Schulz, MD, professor of emergency medicine at UTHealth Houston and EMS physician director for the city of Houston, explains why bystander CPR can more than double a person's chances of survival and how taking action can help save a life.
Here's what to do if someone is unresponsive and not breathing normally:
1. Call 911 immediately or ask someone nearby to call.
2. Start chest compressions by placing your hands in the center of the chest and pushing hard and fast.
3. Keep a steady rhythm of 100 to 120 compressions per minute, allowing the chest to fully recoil.
4. Use an AED if one is available and follow its instructions. Continue CPR until emergency responders arrive, or the person begins to respond.
You don't have to be a healthcare professional to make a lifesaving difference.
