When someone’s heart stops, there is no time to wonder whether your CPR technique is still sharp. Every compression, breath, and pause matters. Even trained healthcare professionals can fall into bad habits during a high-pressure emergency, especially if it has been a while since their last hands-on CPR course.
The good news is that most CPR mistakes are preventable with regular practice and the right training. Here are five common CPR mistakes and how to avoid them when every second counts.
LBW Training Center helps healthcare professionals sharpen their CPR skills through American Heart Association training focused on essential life-saving techniques, including CPR, BLS, ACLS, and PALS. With daily classes at multiple Arizona locations and a low-stress, hands-on learning environment, LBW makes it easier to build confidence, avoid common CPR mistakes, and stay prepared for real emergencies.
Inadequate Compression Depth
One of the most common mistakes with CPR is not pushing deep enough during chest compressions. Shallow compressions may not create enough blood flow to support the brain and vital organs.
For adults, compressions should be deep enough to be effective while still allowing full chest recoil between compressions. In a stressful emergency, it is easy to underestimate how much pressure is needed.
How to avoid it: Practice regularly with quality CPR training equipment and instructor feedback. Hands-on repetition helps you understand what proper compression depth feels like, so you can perform more confidently in a real emergency.
Compressions That Are Too Fast or Too Slow
CPR requires the right rhythm. If compressions are too slow, circulation may be inadequate. If they are too fast, the chest may not recoil fully, which can also reduce blood flow.
The goal is to have a steady, controlled compression rate without rushing or slowing down under pressure.
How to avoid it: Use instructor guidance, CPR feedback tools, or a steady mental rhythm during training to build muscle memory. Practicing at the correct pace can make it easier to stay consistent during an emergency.
Inadequate Chest Recoil
Full chest recoil is just as important as compression depth. If you lean on the chest between compressions, the heart may not refill properly with blood before the next compression.
This mistake can happen when rescuers become tired or overly focused on pushing hard. Over time, even small technique errors can reduce the quality of CPR.
How to avoid it: Focus on allowing the chest to rise between compressions while keeping your hands in position fully. Switching compressors when fatigue sets in can also help maintain high-quality CPR.
Excessive Ventilation
Giving breaths too forcefully or too often can interfere with effective resuscitation. Excessive ventilation may increase pressure in the chest and make it harder for blood to circulate properly.
This is especially common in team settings when communication is unclear or the rescuer providing breaths is anxious.
How to avoid it: Deliver each breath steadily and watch for visible chest rise. In team scenarios, communicate clearly so compressions and ventilations stay coordinated.
Delayed Compressions or Unnecessary Interruptions
Stopping compressions too often or for too long can reduce the effectiveness of CPR. Interruptions may occur during role changes, airway management, AED use, or when there is confusion about what should happen next.
In an emergency, every pause matters. The goal is to keep compressions going as consistently as possible.
How to avoid it: Assign clear roles, communicate quickly, and practice team-based scenarios. Training helps providers move with more confidence and minimize unnecessary interruptions.
