CPR for Pregnant and Obese Individuals – Is it Different?

How Does Pregnancy & Obesity Affect CPR?

Cardiopulmonary Resuscitation (CPR) is a lifesaving procedure performed when someone’s heartbeat or breathing has stopped. It involves chest compressions and rescue breaths to maintain blood circulation and oxygenation until emergency medical personnel arrive. The core principles of CPR remain the same across different populations, but certain considerations are necessary when performing CPR on pregnant and obese individuals. Body weight can impact the effectiveness of CPR, requiring adjustments in positioning, hand placement, and the use of assistive tools. Online Basic Life Support (BLS) classes provide comprehensive training on these variations, ensuring readiness in diverse emergency situations.

Performing CPR on Pregnant Women

Concerns and Misconceptions

Bystanders often hesitate to perform CPR on pregnant women due to fear of harming the unborn child. This hesitation can be life-threatening as both the mother and the fetus rely on immediate intervention for survival.

Technique and Safety

  • Chest Compressions: CPR on pregnant women involves the same chest compression techniques as on non-pregnant adults. Compressions should be at least 2 inches deep and at a rate of 100-120 compressions per minute. Proper compressions help maintain blood flow to the vital organs, including the uterus and placenta, ensuring oxygen delivery to the fetus.
  • AED Use: Automated External Defibrillators (AEDs) are safe to use on pregnant women. The electrical shock from an AED is directed to the heart and does not harm the fetus. If an AED is available, follow the device prompts and apply it as you would for any adult patient.
  • Positioning: If possible, perform chest compressions slightly to the left of the sternum to relieve pressure on the inferior vena cava and improve blood return to the heart. If a second rescuer is present, they can manually displace the uterus to the left to further improve circulation.
  • Emergency Response: Prompt CPR and defibrillation are critical. Without CPR, the chances of survival for both the mother and the fetus decrease dramatically. Always prioritize starting CPR immediately if a pregnant woman is in cardiac arrest.

Performing CPR on Obese Individuals

Challenges and Considerations

Performing CPR on obese individuals can be challenging due to increased body mass, which makes it harder to achieve the necessary compression depth. Obese patients present unique challenges and considerations during CPR, such as the need for specific guidelines and adjustments to ensure effective resuscitation. However, effective CPR can still be performed with certain adjustments and considerations.

Technique and Safety of Chest Compressions

  • Chest Compressions: Ensure compressions are at least 2 inches deep and at a rate of 100-120 per minute. Obesity may require the rescuer to apply more force to achieve the proper compression depth. Effective compressions are crucial for maintaining blood flow to the brain and vital organs. Using CPR manikins designed to simulate obese patients can help rescuers practice and adjust their techniques for real-life scenarios.
  • Strength Considerations: In situations with multiple bystanders, the largest and strongest person available should perform chest compressions to ensure they are deep and effective. This helps maintain the necessary compression depth to sustain life until professional help arrives.
  • Continuous Compressions: If rescue breaths are not possible or safe, continuous chest compressions (hands-only CPR) should be performed. Continuous compressions are better than ineffective attempts at breaths and help maintain vital blood circulation.

Importance of CPR Training and Certification

Knowledge and Confidence

Online CPR/BLS classes provide comprehensive training, covering the specifics of performing CPR on pregnant and obese individuals. These courses teach the correct techniques, the importance of effective compressions, and the safe use of AEDs in various scenarios.


CPR certification is valid for a specific period, after which recertification is necessary to keep skills current. Online recertification courses are available, allowing individuals to refresh their knowledge and ensure they remain proficient in CPR techniques.

Key Steps in CPR for Pregnant and Obese Individuals During Cardiac Arrest

  1. Check Responsiveness: Tap and shout to check if the person is responsive. If there is no response, call for emergency help immediately.
  2. Open the Airway: Tilt the head back and lift the chin to open the airway. Check for breathing.
  3. Begin Compressions: Start chest compressions immediately if there are no signs of breathing or only gasping. Ensure compressions are at least 2 inches deep and at a rate of 100-120 per minute.
  4. Use an AED: If available, apply the AED pads and follow the device prompts. Ensure no one is touching the patient when delivering a shock.
  5. Continue CPR: Keep performing CPR until emergency medical personnel arrive and take over or until the person shows signs of life, such as movement or breathing. The emergency department plays a crucial role in managing and continuing care for obese patients after initial CPR, including the use of specialized compression devices.


    CPR is a vital skill that can save lives in emergencies. While the core principles of CPR are consistent, understanding the specific considerations for pregnant and obese individuals ensures that CPR is performed effectively and safely. Online BLS and CPR training courses provide the knowledge and confidence needed to perform CPR in any situation.

    By enrolling in CPR training and staying certified, you can be prepared to act in emergencies, providing critical support until professional help arrives. CPR training is also crucial for disease control and public health, particularly in the context of obesity-related complications.
