Common CPR Questions and Answers
Short answer
Common CPR questions typically address what CPR involves, how to properly perform it, legal considerations, and testing details. CPR is an emergency procedure using chest compressions and rescue breaths to help someone whose heart or breathing has stopped. Laws and requirements vary by state, employer, or school, so checking local regulations is essential. CPR tests often quiz on step sequences, compression techniques, and emergency responses.
What is CPR and why is it important?
CPR, or cardiopulmonary resuscitation, is a lifesaving technique used when a person’s heart stops beating or they stop breathing. The main purpose is to manually maintain blood flow and oxygen delivery to vital organs, especially the brain, until professional medical help arrives or the heart restarts. Without CPR, brain damage can start within minutes due to lack of oxygen. CPR involves two main actions: chest compressions, which simulate the heart pumping blood, and rescue breaths, which provide oxygen to the lungs.
Understanding why CPR is crucial helps emphasize why learning it can save lives in various emergencies, including cardiac arrest, drowning, or choking incidents. For example, if you find someone collapsed and unresponsive, performing CPR immediately can double or even triple their chance of survival. CPR’s role in emergencies is explained in detail in What CPR Stands For and Its Purpose.
What are the basic steps to perform CPR correctly?
Performing CPR involves a clear sequence of steps designed to maximize effectiveness and safety. For adults, follow this process:
- Check the scene for safety. Ensure the area is safe for you and the victim.
- Check responsiveness. Tap the person’s shoulder and shout, “Are you okay?”
- Call for help. If no response, call 911 or direct someone else to call.
- Open the airway. Tilt the head back slightly and lift the chin.
- Check for breathing. Look, listen, and feel for no more than 10 seconds.
- Start chest compressions. Place the heel of one hand on the center of the chest, place the other hand on top, and press down hard and fast—at least 2 inches deep and 100-120 compressions per minute.
- Give rescue breaths. After 30 compressions, give 2 breaths by pinching the nose, covering the mouth, and blowing until the chest rises.
- Repeat cycles. Continue cycles of 30 compressions and 2 breaths until help arrives or the person shows signs of life.
For children and infants, compression depth and hand/finger placement differ. For example, infants require two fingers for compressions about 1.5 inches deep. Always follow the specific guidelines for the victim’s age. These steps and age variations are explained further in CPR Steps Explained Clearly.
What kinds of questions are on CPR certification tests?
CPR certification exams, whether written or practical, focus on your knowledge and ability to perform lifesaving actions correctly. Common written test questions include:
- What is the correct hand placement for chest compressions?
- How deep and fast should compressions be?
- What is the correct sequence of steps when starting CPR?
- How do you check if someone is breathing?
- What should you do if the victim starts choking?
- When and how do you use an Automated External Defibrillator (AED)?
Practical tests usually require demonstrating CPR on a manikin, showing proper compression technique, rescue breaths, and AED use. For example, you might be asked: “Show how to perform 30 compressions followed by 2 breaths on an adult manikin.” Questions also cover legal and safety considerations, such as when to stop CPR or how to protect yourself from infections.
Many CPR training courses provide sample test questions and practice scenarios. Reviewing these will help improve confidence and readiness. For beginners, CPR for Beginners: How to Get Started offers helpful preparation tips.
What legal protections and rules affect CPR?
Legal protections for people performing CPR are generally provided by Good Samaritan laws, which most states have enacted. These laws protect individuals who provide emergency help from liability, provided they act in good faith, without gross negligence, and within their training limits. However, rules vary widely by state, employer, and setting.
- State laws: Check your state’s specific Good Samaritan statute for details. Some states require reporting CPR attempts to authorities.
- Employer policies: Many workplaces require CPR certification and have rules about when and how employees should perform CPR.
- Schools and contracts: Some schools or contracts specify CPR training for staff or participants, with specific procedures to follow.
If you are unsure about legal protections or requirements, contact local health departments, legal aid organizations, or CPR certification providers for guidance. Understanding these rules helps protect both you and the person you assist.
How is CPR performed differently on infants and children?
CPR techniques vary depending on the victim’s age because infants and children have smaller, more delicate bodies and different physiological needs.
- For infants (under 1 year): Use two fingers placed just below the nipple line for chest compressions. Compress about 1.5 inches deep at a rate of 100-120 compressions per minute. Rescue breaths should be gentle, covering both the infant’s nose and mouth with your mouth.
- For children (1 year to puberty): Use one or two hands (depending on the child’s size) on the center of the chest. Compress about 2 inches deep at the same rate as adults. Rescue breaths are given similarly but more gently than for adults.
Knowing these distinctions ensures CPR is effective and reduces the risk of injury. For detailed examples and practice scenarios, see CPR Examples: Real-Life Situations and Techniques.
What are some key tips for effective CPR?
Effective CPR requires proper technique, timing, and minimizing delays. Follow these tips to improve outcomes:
- Push hard and fast: Compress at least 2 inches deep (adults) at a rate of 100-120 compressions per minute. Imagine the beat of the song “Stayin’ Alive” to keep the rhythm.
- Minimize interruptions: Try not to stop compressions except to give breaths or when professionals take over.
- Allow full chest recoil: Let the chest expand completely between compressions to allow blood to fill the heart.
- Use both hands: Place one hand on top of the other for better force and control.
- Use an AED as soon as possible: Follow AED voice prompts and resume CPR immediately after shock delivery.
- Stay calm and focused: Confidence improves performance, so practice regularly and review CPR steps.
Here is a quick reference table summarizing compression guidelines:
| Victim Type | Compression Depth | Compression Rate | Hand/Finger Placement |
|---|---|---|---|
| Adult | At least 2 inches | 100-120/min | Two hands center of chest |
| Child | About 2 inches | 100-120/min | One or two hands center of chest |
| Infant | About 1.5 inches | 100-120/min | Two fingers just below nipple line |

Where can you get certified or learn CPR?
CPR certification is available through organizations like the American Red Cross, American Heart Association, and local community centers or health departments. Many offer:
- In-person classes: Hands-on training with manikins and instructors.
- Blended courses: Online learning combined with an in-person skills session.
- Online-only courses: Usually for recertification or hands-only CPR.
Some workplaces, schools, or volunteer groups require CPR certification or offer it free of charge. To find a course, search for “CPR classes near me” or visit the websites of reputable organizations. Certification usually lasts two years, after which refresher training is recommended to stay current with updated guidelines.
For beginners, CPR for Beginners: How to Get Started explains how to find and choose the right course.
When should you stop CPR once started?
Knowing when to stop CPR is as important as knowing how to start it. Stop CPR only when:
- The person shows clear signs of life, such as breathing normally, moving, or coughing.
- A trained medical professional or emergency responder takes over.
- You are physically unable to continue due to exhaustion or injury.
- The scene becomes unsafe for you to remain.
Continuing CPR without interruption improves the chances of survival, even if the person looks unchanged for several minutes. Stopping too soon can reduce lifesaving potential. Always try to stay calm and focused during CPR and call for emergency help immediately.
Frequently asked questions
Can I perform CPR if I am not trained?
Yes. Hands-only CPR, which involves chest compressions without rescue breaths, can be performed by untrained bystanders. It helps circulate blood until professional help arrives. Formal training improves effectiveness.
How often should I renew my CPR certification?
CPR certifications usually expire after two years. Taking refresher courses ensures you remain current with the latest techniques and guidelines.
What do I do if the person starts breathing during CPR?
If the person starts breathing normally, stop CPR and place them in the recovery position—on their side to keep the airway clear—and monitor until help arrives.
Is it safe to perform mouth-to-mouth rescue breaths during COVID-19?
During the pandemic, hands-only CPR is recommended for untrained rescuers to reduce infection risk. Trained providers may use personal protective equipment (PPE) and follow updated guidelines.
Can CPR cause harm or injury?
CPR may cause rib fractures or bruising because compressions require force. However, the potential benefit of saving a life outweighs the risk of injury.
What should I do if I see someone choking and unresponsive?
Call 911 immediately and begin CPR if the person is unresponsive. Chest compressions can help dislodge the object blocking the airway.
