CPR
CPR for Adults: A Life-Saving Skill for Emergencies
Cardiopulmonary resuscitation (CPR) is a critical life-saving procedure that can help keep someone alive after their heart stops beating or they stop breathing. It involves chest compressions and rescue breaths that help restore blood circulation and oxygen to the brain and vital organs. In emergencies such as cardiac arrest, the faster you act, the higher the chances of survival.
In this article, we’ll cover the steps of adult CPR, including when and how to perform it, as well as important considerations to ensure that you’re doing it safely and effectively.
When to Perform CPR on an Adult
CPR should be performed if an adult is:
- Unresponsive: If the person is unconscious and unresponsive to being touched or spoken to, CPR should be started immediately.
- Not Breathing or Gasping: If the person is not breathing or is only gasping, this is a sign that they may be experiencing cardiac arrest, and CPR is necessary.
- No Pulse: If you cannot feel a pulse, or if the person’s heart has stopped beating, CPR should be initiated right away.
It’s important to note that CPR should be performed immediately—delaying it could decrease the chances of survival. If you’re unsure whether CPR is needed, it’s always better to start CPR and call for help than to wait.
How to Perform CPR on an Adult: Step-by-Step Guide
1. Check for Responsiveness and Breathing
- Tap and Shout: Gently tap the person on the shoulder and shout loudly, “Are you okay?” to see if they respond.
- Check for Breathing: Look at the person’s chest to see if it rises and falls. Listen for normal breathing sounds. If the person is not breathing or only gasping, and they are unresponsive, call 911 (or your local emergency services number) for help.
2. Call 911 (or Your Local Emergency Number)
- If you’re alone, call 911 yourself before starting CPR. If someone else is around, ask them to call 911 while you begin CPR.
- When calling 911, clearly state that the person is unconscious and not breathing, and give your location so help can arrive as quickly as possible.
3. Position the Person on Their Back
- Lay the person on a firm surface (e.g., the floor or a solid, hard surface) if they are not already.
- Avoid doing CPR on a soft surface, such as a bed, as this can reduce the effectiveness of chest compressions.
4. Chest Compressions
Chest compressions are the foundation of CPR. These compressions help circulate blood to the brain and heart until normal heart function can be restored.
- Hand Placement: Place the heel of one hand on the center of the person’s chest, just below the sternum (breastbone). Place the other hand on top of the first, interlocking the fingers.
- Body Position: Position yourself with your shoulders directly over your hands and your elbows straight, so you can use your body weight to push down on the chest.
- Compression Depth: Push hard and fast, compressing the chest at least 2 inches (5 cm) deep. For adults, this depth is necessary to ensure effective blood flow.
- Compression Rate: Perform chest compressions at a rate of about 100-120 compressions per minute (about the same pace as the song “Stayin’ Alive” by the Bee Gees).
- Full Recoil: Allow the chest to fully rise between compressions, but do not lift your hands off the chest. Let the chest recoil fully before beginning the next compression.
5. Rescue Breaths (Optional)
After 30 chest compressions, you can give two rescue breaths (if trained and able) to help deliver oxygen to the person’s lungs. However, if you are not trained in giving rescue breaths, or are unwilling to do so, continue with chest compressions only.
- Open the Airway: Tilt the person’s head backward to open their airway and lift the chin up gently. This helps the airway stay open.
- Pinch the Nose: Pinch the person’s nose shut with your thumb and forefinger.
- Rescue Breaths: Take a normal breath, cover the person’s mouth with yours, and give two breaths, each lasting about 1 second. You should see the chest rise with each breath.
- If the chest doesn’t rise, re-tilt the head to ensure the airway is open, and try again.
- If the person’s chest still doesn’t rise, it may indicate a blocked airway, and you should begin chest compressions again.
6. Continue CPR
- Continue the cycle of 30 chest compressions followed by 2 rescue breaths until:
- The person starts breathing normally, shows signs of life, or moves.
- Medical personnel arrive and take over.
- You are too exhausted to continue.
If you’re performing CPR by yourself, do not stop until help arrives or the person starts breathing on their own. It’s important to keep up chest compressions, as they are essential to restoring circulation to vital organs.
Hands-Only CPR: An Alternative for Untrained Responders
If you are not trained in CPR or are unable to perform rescue breaths, hands-only CPR is a safe and effective option. In this technique, you focus on providing uninterrupted chest compressions:
- Call 911 immediately.
- Place your hands in the center of the chest and begin chest compressions.
- Compress the chest hard and fast at a rate of 100-120 compressions per minute, ensuring full recoil between compressions.
- Continue until help arrives or the person shows signs of life.
Hands-only CPR is proven to be effective in improving survival rates for adults who experience cardiac arrest, especially when it’s performed early and continuously until help arrives.
Special Considerations
While CPR for adults follows a standard procedure, there are a few important considerations to keep in mind:
- Defibrillation (AED): If an Automated External Defibrillator (AED) is available, use it as soon as possible. An AED is a portable device that can analyze the heart’s rhythm and deliver an electric shock to restore normal heart rhythm. Follow the device’s voice prompts for how to use it.
- Choking: If the person is choking and becomes unresponsive, perform CPR starting with chest compressions. Check the mouth for any visible obstruction before delivering rescue breaths.
- Injuries: If the person has any obvious injuries (such as broken bones or bleeding), perform CPR as usual. The need to restart the heart and breathe for the person is more critical than the injuries.
- Pregnancy: For pregnant women, CPR is generally the same, but you may need to adjust your positioning. Place the person on her left side, if possible, to avoid pressure on the vena cava, a large vein that returns blood to the heart.
How to Prepare for Emergencies
While knowing how to perform CPR is essential, preparing for emergencies in advance can improve your confidence and your ability to respond effectively:
- Take a CPR Course: CPR classes, such as those offered by the American Heart Association (AHA) or the American Red Cross, can teach you how to perform CPR on adults, infants, and children. These courses also cover how to use an AED and handle choking situations.
- Get Certified: Completing a CPR certification course will not only teach you the techniques but also ensure that you’re updated on the latest guidelines and best practices.
- First Aid Training: In addition to CPR, learning basic first aid can help you handle other emergency situations, like bleeding, fractures, burns, and other medical emergencies.
- Know Where the AEDs Are: Many public places, such as airports, gyms, and shopping malls, have AEDs installed. Familiarize yourself with their location in case you need to use one in an emergency.
Conclusion
CPR is a vital, life-saving skill that can help stabilize someone experiencing cardiac arrest or respiratory failure until emergency medical personnel arrive. By performing chest compressions (and rescue breaths if trained), you can help circulate blood and oxygen to vital organs, greatly improving the chances of survival. Hands-only CPR, while simple, is also incredibly effective and can be performed by anyone.
Taking a CPR course and practicing the steps can prepare you to respond confidently in an emergency. By acting quickly and efficiently, you can make the difference between life and death in a critical situation.
