Chest Compressions- The First Line Response

Chest Compressions
  • Updated on: May 19, 2024

The moments that follow a cardiac arrest, is the most critical time that demands swift intervention. Prompt and effective decisions can literally mean the difference between life and death. Chest Compressions is a vital technique that lies in the forefront of emergency response. 

The fundamental component of CPR (cardiopulmonary resuscitation) is chest compressions. This step ensures uninterrupted blood and oxygen supply to the vital organs. 

Whether you are a seasoned healthcare professional or just a bystander, understanding the importance of delivering effective and timely chest compressions can make all the difference.

Doubling or tripling a person’s chance of survival, with the help of this blog, know the essential steps to deliver effective chest compressions. 

What is the guideline for delivering the most effective compression?

In an emergency situation where someone experiences cardiac arrest, performing effective chest compressions is critical to maintaining blood flow to the brain and vital organs until professional help arrives. Adhering to the proper guidelines ensures that your efforts are as beneficial as possible. Here are the key guidelines for delivering the most effective chest compressions:

  • Positioning: Place the heel of one hand on the center of the person’s chest, on the lower half of the sternum. Place your other hand on top, interlocking your fingers.
  • Depth: Compress the chest at least 2 inches (5 cm) deep for adults. For children, compress about 2 inches (5 cm), and for infants, compress about 1.5 inches (4 cm).
  • Rate: Aim for a compression rate of 100 to 120 compressions per minute. This can be timed to the beat of songs like “Stayin’ Alive” by the Bee Gees.
  • Allow Full Recoil: After each compression, allow the chest to fully recoil to its normal position. This ensures the heart refills with blood between compressions.
  • Minimize Interruptions: Keep interruptions to chest compressions to a minimum. If you need to stop, do so for as little time as possible.
  • Proper Body Mechanics: Keep your shoulders directly over your hands and use your body weight, not just your arms, to perform compressions. This helps maintain consistent depth and reduces fatigue.
  • Hand Placement: Ensure your hands stay in contact with the chest at all times to avoid losing your place and reducing effectiveness.

By following these guidelines, you can maximize the effectiveness of your chest compressions, providing the best possible support to someone in cardiac arrest until professional medical help arrives.

What are the common problems encountered while delivering chest compression?

Delivering chest compressions during an emergency can be challenging. Several common problems can arise that may reduce the effectiveness of compressions or pose additional risks. Recognizing and addressing these issues is crucial to providing the best care possible. Here are some of the most frequently encountered problems:

  • Incorrect Hand Placement: Placing hands too high or too low on the chest can lead to ineffective compressions or even injury to the ribs or sternum.
  • Inadequate Compression Depth: Compressing the chest too shallowly fails to generate sufficient blood flow to vital organs, while excessive depth can cause injury.
  • Improper Compression Rate: Compressing too slowly or too quickly can affect the effectiveness of blood circulation. Aim for 100 to 120 compressions per minute.
  • Insufficient Recoil: Not allowing the chest to fully recoil between compressions can prevent the heart from refilling with blood, reducing overall circulation.
  • Fatigue: Performing chest compressions is physically demanding, and rescuers can quickly tire, leading to reduced compression quality over time.
  • Interruptions: Frequent or prolonged interruptions in compressions can significantly decrease the chances of survival. Strive to minimize pauses.
  • Inconsistent Technique: Variations in the force, rate, or depth of compressions can lead to inconsistent blood flow, reducing the overall effectiveness of CPR.
  • Poor Body Mechanics: Improper body positioning can lead to inefficient compressions and increased rescuer fatigue. Ensure shoulders are over hands and use body weight for compressions.
  • Failure to Switch Rescuers: In a prolonged resuscitation effort, not switching out tired rescuers can lead to decreased compression quality. Rotate every two minutes if possible.

Addressing these common problems through proper training, practice, can significantly improve the effectiveness of chest compressions. It also increases the chances of a positive outcome for the patient.
