What is the quality measurement for effective CPR regarding compressions?

The quality measurement for effective CPR emphasizes the importance of both the rate and depth of chest compressions. The correct answer specifies compressing at a rate of 100-120 per minute with adequate depth, which aligns with current resuscitation guidelines. This rate is optimized to maximize blood flow during cardiac arrest, ensuring that there is sufficient circulation to vital organs, particularly the heart and brain.

Research has shown that compressing at this rate helps maintain adequate perfusion pressure and improves overall survival rates. Additionally, the guideline specification for "adequate depth" usually refers to compressing to a depth of at least 5-6 cm in adults, which is essential to ensure effective venous return and circulation during cardiac arrest.

The other options do not meet the recognized standards for effective CPR. They either promote a significantly slower compression rate that would be less effective in generating adequate blood flow or suggest rates that exceed recommended levels, which could lead to fatigue and decreased compression quality. Maintaining a focus on both the correct rate and depth is critical in achieving the best outcomes during resuscitation efforts.
