Which of the following are components of high-quality CPR? Select all that apply.
A Chest returns to normal position between each compression
B Compression rate is 100 to 120 per minute
C Each breath lasts at least 2 seconds; chest begins to rise
D Minimize necessary interruptions in chest compressions to less than 10 seconds
E Compression depth is at least 5 inches
F Check for breathing every 30 seconds
The Correct Answer and Explanation is :
The components of high-quality CPR from the options provided are:
A. Chest returns to normal position between each compression
B. Compression rate is 100 to 120 per minute
D. Minimize necessary interruptions in chest compressions to less than 10 seconds
Explanation:
High-quality cardiopulmonary resuscitation (CPR) is essential for improving the chances of survival during a cardiac arrest. Each of the correct components contributes to the overall effectiveness of the procedure.
A. Chest returns to normal position between each compression: Allowing the chest to fully recoil between compressions is crucial because it helps to reestablish blood flow back to the heart. This allows for better venous return and ensures that the heart can fill adequately before the next compression.
B. Compression rate is 100 to 120 per minute: The recommended compression rate during CPR is between 100 and 120 compressions per minute. This rate has been shown to maximize blood flow and oxygen delivery to vital organs, including the brain, during cardiac arrest.
D. Minimize necessary interruptions in chest compressions to less than 10 seconds: Minimizing interruptions in chest compressions is vital for maintaining blood flow to the brain and heart. Research indicates that longer interruptions can significantly decrease the likelihood of survival, hence the recommendation to keep interruptions under 10 seconds whenever possible.
Incorrect Options:
C. Each breath lasts at least 2 seconds; chest begins to rise: While the duration of breaths is important, the correct duration for breaths is typically 1 second per breath with visible chest rise.
E. Compression depth is at least 5 inches: The recommended depth for adult CPR compressions is at least 2 inches (approximately 5 cm), but not specifically 5 inches, which exceeds the recommended depth.
F. Check for breathing every 30 seconds: Checking for breathing is not recommended every 30 seconds during CPR; instead, rescuers should focus on providing continuous compressions and check for responsiveness and breathing before beginning CPR, but not during the process.
In summary, adherence to the correct components of high-quality CPR can significantly increase the chances of survival after cardiac arrest.
