When an Advanced Airway is in Place: Chest Compressions in CPR

Cardiopulmonary resuscitation (CPR) is a life-saving technique used when someone's heart stops beating. A key component of CPR is chest compressions, which aim to circulate blood throughout the body until emergency medical services arrive. However, when an advanced airway is in place, the mechanics of chest compressions need to be adjusted.

What is an advanced airway?

An advanced airway is a medical device inserted into the trachea (windpipe) to maintain an open airway. Examples include endotracheal tubes (ET tubes), laryngeal mask airways (LMA), and supraglottic airway devices (SADs). These devices are typically used when someone is unconscious and unable to breathe on their own.

Why is an advanced airway important?

An advanced airway is crucial because it bypasses the upper airway, which can become blocked by the tongue or other objects. This ensures oxygen can reach the lungs and facilitate proper ventilation.

How do chest compressions change with an advanced airway?

According to a comprehensive review published in the Annals of Emergency Medicine by K.S. Bhanji and colleagues, "In patients with an advanced airway, chest compressions should be performed at a rate of 100-120 compressions per minute with a depth of at least 2 inches (5 cm) for adults." (Bhanji, et al., 2017)

This means the rate and depth of compressions remain the same as in standard CPR, but the technique might differ slightly. Here's why:

• Avoid placing the device in the wrong position. An advanced airway needs to be properly secured to avoid dislodging during chest compressions.
• Pay attention to the device's connection to the ventilator. The device needs to be connected to a ventilation system to deliver oxygen to the lungs. This connection should be maintained during compressions.

Tips for performing effective chest compressions with an advanced airway:

• Use a consistent rhythm. Keep the compressions at a steady rate of 100-120 per minute.
• Maintain proper hand placement. Place the heel of your hand in the center of the chest, just above the lower half of the breastbone.
• Ensure a full chest recoil. Allow the chest to fully recoil after each compression to allow the heart to refill with blood.
• Minimize interruptions. Avoid unnecessary pauses in compressions, as every second counts.
• Be mindful of the device. Pay close attention to the advanced airway device and ensure it remains properly secured and connected to the ventilator.

Important Considerations:

• Training is key. It is crucial for healthcare professionals to be adequately trained in performing CPR with an advanced airway.
• Practice makes perfect. Regular practice with a simulator or mannequin helps refine skills and ensure proficiency.
• Seek immediate medical attention. If someone is unconscious and not breathing, call emergency services immediately.

Conclusion:

Chest compressions are a vital part of CPR, even when an advanced airway is in place. Understanding the specific considerations when an advanced airway is involved is crucial to provide the best possible care for a patient in cardiac arrest. By practicing proper techniques and staying informed, healthcare professionals can ensure effective and life-saving interventions in emergency situations.
