CPR Techniques for Pregnant Women

Cardiopulmonary resuscitation (CPR) is a critical life-saving procedure employed during cardiac arrest to restore blood circulation and breathing. While the fundamentals of CPR remain consistent, administering it to pregnant women demands specific considerations to ensure the safety of both the mother and the unborn baby. These nuances stem from the physiological changes that occur during pregnancy and the need for specialized techniques to optimize outcomes. This comprehensive guide explores the critical adjustments, best practices, and insights necessary for performing CPR on pregnant women, incorporating key highlights from MyCPR NOW’s specialized training programs, including the importance of maternal resuscitation.

Understanding the Physiological Changes in Pregnancy

Pregnancy brings about significant physiological and anatomical changes that directly impact how CPR should be administered. Here are the most important aspects to consider:

1. Increased Blood Volume and Cardiac Output

• During pregnancy, a woman’s blood volume increases by up to 50% to support the growing fetus and meet the metabolic demands of the mother.

• This increased volume enhances the importance of effective chest compressions to maintain adequate circulation.

• CPR techniques must be adjusted to account for these changes, ensuring that blood flow reaches both the mother and fetus.

2. Shifted Organs and Enlarged Uterus

• As the uterus expands, it displaces internal organs such as the diaphragm and stomach.

• This anatomical shift necessitates modifications to hand placement during chest compressions to avoid unintentional injury to the uterus or other organs.

3. Aortocaval Compression

• In the later stages of pregnancy, the enlarged uterus can compress major blood vessels, including the aorta and inferior vena cava, when the mother lies flat on her back.

• This compression can significantly reduce blood flow to the heart, impairing circulation to both the mother and fetus.

• Addressing this issue is critical for maintaining effective CPR.

These physiological changes increase the risk of maternal mortality during maternal cardiac arrest, especially with factors like advanced maternal age and preexisting health conditions contributing to the rising trend over the last 30 years.

Essential CPR Techniques for Performing Chest Compressions on Pregnant Women

Administering CPR to pregnant women involves key modifications to traditional techniques. Below are the essential adjustments:

1. Modified Chest Compression Techniques

• Hand Placement: Place hands slightly higher on the sternum than in standard CPR to avoid compressing the uterus.

• Compression Depth and Rate: Maintain the standard compression depth (at least 2 inches) and rate (100–120 compressions per minute) to ensure effective circulation.

2. Airway and Breathing Management

• Head Tilt-Chin Lift: Ensure the airway remains open by tilting the head back and lifting the chin forward, minimizing obstructions caused by anatomical changes.

• Ventilations: Deliver rescue breaths with a proper seal over the mouth and nose. Look for visible chest rise to confirm effective air exchange.

3. Left Uterine Displacement (LUD)

• To relieve pressure on major blood vessels, manually displace the uterus to the left. This can be achieved by gently pushing the abdomen or tilting the mother to a 15–30-degree angle using a wedge or other support. Manual left uterine displacement is a critical technique for performing high-quality CPR on pregnant women, as it helps to relieve aortocaval compression caused by the enlarged uterus, allowing chest compressions to be more effective when the patient remains in a supine position.

4. Continuous CPR

• Alternate between 30 chest compressions and 2 rescue breaths. Continue this cycle without interruption until professional help arrives or the woman shows signs of recovery.

Common Causes of Maternal Cardiac Arrest in Pregnancy

Understanding the potential causes of cardiac arrest during pregnancy can help responders anticipate complications and act quickly:

1. Pregnancy-Related Complications

• Hemorrhage: Severe bleeding due to conditions like placental abruption or uterine rupture can lead to hypovolemic shock and cardiac arrest.

• Preeclampsia and Eclampsia: High blood pressure disorders can result in seizures or cardiovascular collapse.

• Amniotic Fluid Embolism: A rare but life-threatening condition caused by amniotic fluid entering the bloodstream.

2. General Causes

• Cardiac arrest may also stem from common causes such as arrhythmias, trauma, or drowning. These require immediate intervention using CPR techniques adapted for pregnancy. Additionally, the increased risk of sudden cardiac arrest during pregnancy necessitates tailored resuscitation efforts to address the unique physiological changes and ensure the safety of both the mother and fetus.

Ensuring the Safety of the Unborn Baby

During cardiac emergencies, protecting the fetus is as critical as ensuring the mother’s survival. Here’s how CPR can help:

1. Maternal Blood Flow

• Effective chest compressions ensure oxygen-rich blood continues to flow to the fetus via the placenta.

• Delays in starting compressions can compromise fetal oxygenation, so immediate action is vital.

2. Assessing Fetal Well-Being

• After resuscitation, medical professionals will evaluate the fetus’s condition using ultrasound or fetal monitors to detect signs of distress. While fetal monitors are crucial for continuous monitoring of the fetal heart rhythm, they can be a potential distraction during resuscitation efforts. Therefore, it is recommended to remove fetal monitors during maternal stabilization and reapply them once the mother is stable to monitor for any complications.

3. Preparing for Emergency Birth

• In rare cases, cardiac arrest may induce preterm labor. Responders should recognize signs of imminent delivery and coordinate efforts to ensure the safety of both mother and baby.

Psychological First Aid for Pregnant Women

Emergencies involving pregnant women can be emotionally overwhelming. Providing psychological support is essential:

1. Offering Emotional Reassurance

• Clear communication and compassionate reassurance can alleviate anxiety for the mother and bystanders during a crisis.

2. Managing Stress

• Rescuers are trained to remain composed and focused, ensuring effective care while reducing emotional strain for everyone involved.

Post-CPR Care

Post-CPR care is a critical component of managing maternal cardiac arrest. After successful resuscitation, it is essential to transfer the patient to a hospital for comprehensive evaluation and treatment. Here are the key guidelines for post-CPR care:

1. Targeted Temperature Management: If the patient remains comatose after resuscitation, consider implementing targeted temperature management. This involves cooling the body to a temperature between 32°C and 34°C to minimize brain injury. This step is crucial in improving neurological outcomes after cardiac arrest.

2. Continuous Fetal Monitoring: Once targeted temperature management is initiated, continuous fetal monitoring becomes essential. This helps in detecting potential complications such as fetal bradycardia. Ensuring the well-being of the fetus requires close collaboration with obstetric and neonatal support teams.

3. Obstetric and Neonatal Support: Prompt obstetric and neonatal support is vital to address any pregnancy-related complications that may arise post-resuscitation. This includes monitoring for signs of preterm labor and ensuring the readiness of neonatal care if an emergency birth becomes necessary.

4. Cardiovascular Evaluation: A thorough cardiovascular evaluation should be conducted to identify any underlying conditions that may have contributed to the cardiac arrest. This includes assessing the heart’s function and looking for any signs of cardiovascular disease that need to be managed to prevent future incidents.

5. Psychological Support: Maternal cardiac arrest can be a traumatic experience for both the patient and her family. Providing psychological support is essential to help them cope with the emotional aftermath. This includes offering counseling services and ensuring that the patient and her family receive the necessary emotional care.

By adhering to these post-CPR care guidelines, healthcare providers can optimize outcomes for both the mother and the fetus, ensuring comprehensive care and support during this critical period.
