Confident action can turn bystanders into lifesavers when every moment matters.

When a medical emergency strikes, every second counts. Knowing exactly what to do can be the difference between life and death. From sudden cardiac arrests and choking incidents to building an effective emergency preparedness kit, this guide—based on current medical guidance and expert insights—empowers you with clear steps to act with confidence in critical moments.

Why Immediate Bystander Action is Critical

Medical experts agree: bystander intervention dramatically increases survival rates in emergencies. Whether it’s performing CPR, clearing an airway, or using an automated external defibrillator (AED), your swift action matters. The steps outlined below reflect the latest research and trusted emergency protocols designed to maximize your impact when it matters most.

Understanding the difference between a heart attack and a panic attack can be life-saving. The symptoms can be similar, but the actions you take need to be different. By familiarizing yourself with these distinctions, you can ensure prompt and correct responses in emergency situations. To learn about these critical differences and the best initial response strategies, check out our detailed guide on heart attack vs panic attack.

Cardiac Arrest

Out-of-hospital sudden cardiac arrest claims hundreds of thousands of lives in the U.S. each year. Unfortunately, fewer than 1 in 10 victims survive when no bystander aid is provided. However, performing bystander CPR can raise the survival rate up to 30%, and prompt use of an AED can increase it to 50%. Hands-only CPR, which skips mouth-to-mouth for adults and teens, has been shown to double or triple survival odds.

What Cardiac Arrest Looks Like

Sudden, unexpected collapse
No response to touch or loud voices—even shouting
Not breathing, or gasping for air
Victim does not move or wake up

It's important to be aware of habits that can put your health at risk, especially during emergencies. Many common behaviors can lead to accidents or health crises that might require immediate intervention. To discover which risky habits to avoid and how they can affect your emergency preparedness, read our comprehensive overview of risky habits ER doctors warn against.

What To Do

Call 911 immediately and find an AED if one is available. If you are not alone, have someone else do this while you begin aid.
Lay the victim flat on their back on a firm surface.
Begin Hands-Only CPR:
- Kneel beside the person.
- Place the heel of one hand in the center of their chest (lower half of breastbone).
- Put your other hand on top and interlock your fingers.
- Using your upper body, push down hard—at least 2 inches deep—at a rate of 100-120 compressions per minute (sing the chorus of “Stayin’ Alive” for rhythm).
- Let the chest come fully back up between compressions.
If an AED arrives:
- Turn it on and follow the voice prompts.
- Attach the pads to the chest as directed (one on upper right, one on lower left).
- Stand clear when the AED analyzes and delivers a shock if advised.
- Continue CPR until emergency responders arrive, the victim starts to breathe, or you’re too exhausted to continue.

One critical misstep during first aid is how to handle a bloody nose. While instinct might tell you to lean the head back, this can lead to choking. Instead, it’s vital to understand the best practices for managing nosebleeds efficiently. For effective techniques that can make all the difference, explore our in-depth article on why you should avoid leaning the head back during a nosebleed.

Snow shoveling can pose unexpected health risks, particularly to the heart. Many individuals are unaware just how taxing this chore can be on the body, especially in cold conditions. Understanding these hidden risks can prompt you to take precautions during winter weather. Want to know more about how snow shoveling affects heart health?

What Not To Do

Do not stop rescue efforts unless the person regains consciousness, a professional takes over, the area becomes unsafe, or you physically cannot continue.
Do not perform hands-only CPR on infants or most children; use traditional CPR with rescue breaths.

Tip: Watching a quick, accredited video on hands-only CPR can help you feel prepared. Consider hands-on training with the American Red Cross or another certified provider.

Choking

Choking is a top cause of preventable death, especially in children and older adults. Immediate bystander assistance doubles the chances of survival. Recognizing the signs and knowing how to perform the Heimlich maneuver or back blows is essential.

Signs of Choking

Panic, surprise, or confusion
Clutching throat (universal choking sign)
Inability to talk, produce vocal sounds, or only a weak cough/high-pitched squeak
Pale or blue skin as oxygen drops

What To Do

Call 911 immediately.
If safe, approach to help (move to a location out of traffic or hazards).
If the person is still conscious:
- Deliver 5 firm back blows between the shoulder blades with the heel of your hand.
- If the blockage remains, perform the Heimlich maneuver (abdominal thrusts):
  - Stand behind the person (kneel if it’s a child).
  - Make a fist, place it above the belly button and below the rib cage.
  - Grasp your fist and thrust inward and upward quickly.
  - If the person is pregnant or obese, give chest thrusts instead of abdominal.
- Alternate between 5 back blows and 5 abdominal thrusts.
- If the person becomes unconscious:
  - Lay them flat and start CPR while waiting for emergency help.
  - If you can see the object in their mouth (and only then), try to remove it with your finger.

What Not To Do

Do not try to remove the object blindly if it isn’t visible.
Do not interfere if the person can speak, cough forcefully, or breathe—encourage them to keep coughing instead.

Building Your Emergency Preparedness Kit

An emergency preparedness kit ensures you and your family are equipped to handle sudden crises—from severe weather to medical emergencies—when professional help might be delayed. This kit should be accessible, easy to carry, and replenished regularly.

Basic Kit Essentials

Water: At least 1 gallon per person, per day (3-day supply minimum)
Non-perishable food: Enough for each person, for at least three days
First aid kit: Stocked with bandages, antiseptics, gloves, and essential medicines (7-day supply recommended)
Battery-powered or hand-crank radio (NOAA weather alerts preferable)
Flashlight and extra batteries
Multi-purpose tool (such as a Swiss Army knife)
Sanitation and personal hygiene supplies
Copies of vital documents (medical info, insurance, ID, birth certificates)
Emergency blanket and spare warm clothing
Cell phone with extra charger (portable power bank is helpful)
Cash (small bills) and a map of your area

Additional Items for Family Needs

Medical supplies: glasses, hearing aids, syringes, extra batteries
Baby supplies: bottles, formula, food, diapers
Games or calm-down toys for children
Pet supplies: food, collar, ID tags, leash, portable carrier
Manual can opener
Two-way radios for group communication
Extra set of keys (home/car)

Hazard-Dependent Additions

Whistle for signaling for help
N95 or surgical masks for dust/fumes
Rain gear, sturdy shoes, warm hat, gloves
Plastic sheeting, duct tape, scissors
Tools for securing your home or shelter
Household liquid bleach for water purification
Sleeping bags/extra blankets

Practical Advice for Kit Storage and Maintenance

Store your kit in a clearly labeled, accessible location known to all family members.
Test flashlights, radios, and power banks every few months.
Periodically check expiration dates on food, water, and medications; replace as needed.
Customize your kit for local disasters (earthquakes, storms, etc.) and personal health needs.

Frequently Asked Questions (FAQs)

What is the difference between a heart attack and cardiac arrest?

Cardiac arrest is when the heart suddenly stops beating, often leading to loss of consciousness and stopped breathing. A heart attack is caused by blocked blood flow to the heart muscle and may present as chest pain or discomfort, shortness of breath, and other symptoms. Both are emergencies, but cardiac arrest requires immediate hands-only CPR and AED use.

How do I know if someone is choking or just coughing?

A choking person cannot speak, makes only faint noises or squeaks, and shows signs of panic or blue skin. If they can cough forcefully or talk, encourage them to keep coughing to dislodge the object themselves.

Do hands-only CPR and AED use work on children?

Hands-only CPR is best for teens and adults who suddenly collapse. For infants and most young children, use traditional CPR with both chest compressions and rescue breaths. AEDs can be used on children, but be sure to use pediatric pads if available.

What if I’m not trained in CPR or first aid?

Even without formal training, you can perform hands-only CPR by pushing hard and fast in the center of the chest. AEDs provide clear voice instructions and can be safely used by untrained bystanders. Taking a certified class from the American Red Cross or a local provider is still strongly encouraged.

How often should I update my emergency preparedness kit?

Review your kit every six months. Replace expired food, water, medications, and batteries. Update copies of important documents and adapt your kit for family changes (babies, pets, health issues, or moves).
