Cardiopulmonary resuscitation (CPR) is a life-saving skill that anyone can learn, yet even trained individuals occasionally make mistakes in the heat of the moment. These errors can reduce the effectiveness of CPR or even cause harm to the person in need. Whether you’re a first-time learner, a seasoned healthcare professional, or simply a concerned parent, understanding common CPR mistakes and how to avoid them is vital to improving outcomes in emergencies.
This post will guide you through some of the most frequent CPR errors, explain why they matter, and provide actionable tips for correcting your technique. By the end of this article, you’ll feel more confident and prepared to step in when seconds count.

Why Proper CPR Technique Matters
CPR is designed to maintain partial circulation of blood and oxygen to vital organs when the heart has stopped. For every minute without CPR, the survival rate of someone in cardiac arrest drops by 7–10%. Proper technique is crucial to ensure maximum effectiveness, as even small errors can make a big difference.
Now, let's break down the most common CPR mistakes and how you can avoid them.
1. Not Starting CPR at All
The Mistake:
Many people hesitate to perform CPR due to fear of doing it wrong, causing harm, or legal concerns. This hesitation can cost precious time and potentially lead to worse outcomes for the patient.
Why It Matters:
Even imperfect CPR is better than doing nothing. Without intervention, cardiac arrest is almost always fatal, while bystander CPR can double or even triple the chances of survival.
How to Avoid It:
- Remember, Good Samaritan laws exist to protect those providing CPR in good faith, as long as they act within their level of training.
- Your first steps should always be checking responsiveness, calling 911, and starting chest compressions if the person is unresponsive and not breathing.
- Practice CPR frequently using manikins to feel more confident in real emergencies.
2. Incorrect Hand Placement
The Mistake:
Placing hands too far to the side, too low, or too high on the chest can reduce the effectiveness of compressions and may even cause internal injuries.
Why It Matters:
Compressions work by squeezing the heart between the sternum (breastbone) and spine to pump blood. Incorrect placement can lead to broken ribs without effectively moving blood through the heart.
How to Avoid It:
- Use the heel of your hand and position it in the center of the chest on the lower half of the breastbone.
- Interlock your fingers and keep your elbows straight, applying pressure using your upper body rather than your arms.
- Always visualize your landmarks during training and familiarize yourself with the correct placement.
3. Applying Insufficient Depth or Force
The Mistake:
Some people are hesitant to push hard and deep enough during chest compressions. This can stem from fear of injuring the patient.
Why It Matters:
Compressions that are too shallow fail to effectively circulate blood to the brain and other vital organs. The recommended depth for adult CPR is at least 2 inches (5 cm) per compression.
How to Avoid It:
- Remind yourself that ribs may break during effective CPR, and that’s okay. It's better to provide high-quality compressions than to hold back.
- Use your body weight and lean into the chest rather than relying on arm strength.
- Enroll in refresher courses to practice the correct pressure and depth on CPR manikins.
4. Not Maintaining the Correct Compression Rate
The Mistake:
Performing compressions too quickly or too slowly can diminish your effectiveness. People under stress often speed up, while those tiring out may slow down.
Why It Matters:
The ideal compression rate is 100–120 compressions per minute. Going too fast doesn’t allow the heart to refill with blood, while going too slow reduces blood flow to essential organs.
How to Avoid It:
- The beat of some popular songs (like "Stayin’ Alive" by the Bee Gees) matches the correct compression rhythm. Practice keeping pace with these tunes.
- Use metronomes or apps during training sessions to synchronize your compressions.
- Take turns performing CPR during longer emergencies if others are capable, ensuring the person providing compressions doesn't tire out.
5. Interrupting Compressions Too Often or for Too Long
The Mistake:
Pausing compressions frequently or for extended periods to perform other tasks, such as rescue breaths or checks, can interrupt the flow of oxygenated blood.
Why It Matters:
Every pause reduces blood flow to the brain and heart. Research shows that uninterrupted chest compressions are one of the main factors in improving survival.
How to Avoid It:
- Minimize pauses to less than 10 seconds when delivering rescue breaths or using an automated external defibrillator (AED).
- Delegate tasks like AED operation or calling 911 to others if they are available, letting you focus on compressions.
- Stay focused and avoid distractions, ensuring compressions are your priority unless the person revives.
6. Forgetting to Use an AED
The Mistake:
Some people delay using an AED (Automated External Defibrillator) or avoid it altogether because they’re intimidated or unsure how to operate it.
Why It Matters:
The AED delivers life-saving shocks that can restore a normal heart rhythm during sudden cardiac arrest. Without it, survival rates drop significantly.
How to Avoid It:
- Familiarize yourself with AED use during CPR training. Modern units are designed to be user-friendly and include voice prompts to guide you.
- Use the AED as soon as it’s available, pausing compressions only briefly to attach pads and analyze the heart rhythm.
- Make sure you know the location of AED devices in your workplace, school, or other common environments.
7. Improper Technique During Rescue Breaths
The Mistake:
Providing too much air or incorrectly sealing the mouth and nose during rescue breaths are frequent errors.
Why It Matters:
Over-ventilation can cause air to enter the stomach rather than the lungs, increasing the likelihood of vomiting. Poor sealing reduces the effectiveness of the breaths.
How to Avoid It:
- Tilt the head back and lift the chin to open the airway properly.
- Create a tight seal around the mouth or nose, depending on the method used.
- Deliver breaths gently—just enough to make the chest rise.
8. Neglecting Self-Care During CPR
The Mistake:
It’s easy to forget about your own physical stamina, especially during high-stress emergencies, which often leads to poor compressions as you tire.
Why It Matters:
CPR can be physically exhausting, and effectiveness drops when the rescuer becomes fatigued.
