Answer :
Final answer:
To achieve a high chest compression fraction during CPR, compress at a depth of at least 2 inches, minimize pauses in chest compressions, and allow full chest recoil during compressions.
Explanation:
To achieve a high chest compression fraction during CPR, there are several key steps to follow:
- Compress at a depth of at least 2 inches: Apply pressure on the sternum (chest bone) to compress the heart enough to push blood into the circulatory system.
- Minimize pauses in chest compressions: Continuously perform chest compressions without interruptions to maintain blood flow.
- Allow full chest recoil during compressions: After each compression, allow the chest to rebound fully to its original position before initiating the next compression.
By following these steps, you can maximize the effectiveness of chest compressions and achieve a high chest compression fraction.
Final answer:
To achieve a high chest compression fraction in CPR, compress the chest at a depth of at least 2 inches, minimize pauses, deliver a shock in 15 seconds or less, and allow full chest recoil.
Explanation:
To achieve a high chest compression fraction, which is crucial for effective cardiopulmonary resuscitation (CPR), certain guidelines must be followed:
Compress at a depth of at least 2 inches (5 cm) to ensure adequate circulation.
Minimize pauses in chest compressions to provide consistent blood flow to vital organs, especially the brain.
Deliver a shock in 15 seconds or less if an automated external defibrillator (AED) is available, to reduce downtime.
Allow full chest recoil during compressions to promote blood flow back to the heart for the next compression.
Trained first responders include both chest compressions and mouth-to-mouth breathing in CPR, however, bystanders should perform compression-only CPR. The rhythm of compressions should be steady and match the beat of the song "Staying Alive" from the Bee Gees, which equates to a rate of 100-120 compressions per minute.
