Performing CPR on someone in their third trimester of pregnancy presents unique challenges due to the size and position of the uterus. Standard CPR techniques may not be as effective, and modifications are necessary to ensure efficient chest compressions. This article will detail the recommended CPR position and techniques for this specific situation.

Understanding the Challenges of Third-Trimester CPR

The enlarged uterus in a third-trimester pregnant person significantly impacts chest compression effectiveness. The uterus can impede adequate chest compression depth and can also compromise blood flow to the heart and brain. Standard CPR techniques, which assume a uniform chest cavity, are not ideal in this situation.

The Recommended CPR Position

The recommended position for CPR on a pregnant person in their third trimester is a left lateral tilt. This involves turning the pregnant person onto their left side, slightly tilting them to relieve pressure on the vena cava.

Why the Left Lateral Tilt?

The inferior vena cava, a major vein carrying blood back to the heart, is compressed by the weight of the uterus when a pregnant person lies on her back. Turning her onto her left side alleviates this pressure, improving blood return to the heart and facilitating more effective CPR. This simple adjustment can significantly improve the chances of success.

Adjustments for the Rescuer

The rescuer may need to adjust their hand placement slightly to accommodate the pregnant belly. However, the focus remains on providing consistent, effective compressions.

Step-by-Step Guide to Performing CPR in the Left Lateral Tilt Position

1. Assess the Scene: Ensure safety for both the victim and yourself.
2. Call for Help: Dial emergency services immediately.
3. Check for Responsiveness: Gently shake the person and shout, "Are you okay?"
4. Check for Breathing: Look, listen, and feel for breathing for no more than 10 seconds.
5. Start CPR: If the person is unresponsive and not breathing normally, begin CPR. Carefully roll the pregnant person onto their left side, supporting their head and neck.
6. Hand Placement: Place the heel of one hand on the center of the chest, just below the nipple line. Place the other hand on top of the first, interlacing your fingers.
7. Compressions: Push hard and fast, aiming for a depth of at least 2 inches. Allow the chest to fully recoil between compressions.
8. Breaths: If trained in rescue breaths, give 2 breaths after every 30 chest compressions. Ensure an adequate seal is maintained for effective breaths.

Important Considerations

• Continuous Monitoring: Monitor the pregnant person's condition continuously.
• Professional Assistance: Seek professional medical assistance as soon as possible.
• Training: CPR training is crucial. Consider taking a specialized CPR course that includes training for pregnant individuals.

Conclusion

Performing CPR on a pregnant person in their third trimester requires modified techniques to account for the physiological changes during pregnancy. The left lateral tilt position is crucial for improving blood return to the heart and enabling more effective chest compressions. Remember, immediate action and proper techniques are essential for increasing the chances of survival. It is strongly recommended to complete a CPR course to gain proficiency in these life-saving skills. Knowing the recommended CPR position for a third-trimester pregnant person can make a significant difference in a critical situation.
