What is the recommended depth and timing of chest compressions during CPR?

2-3 cm and 120 times per minute
4-5 cm and 100 times per minute
3-4 cm and 80 times per minute
5-6 cm and 90 times per minute

The correct answer is: 4-5 cm and 100 times per minute

The recommended depth and timing of chest compressions during CPR is generally set at a depth of 5-6 cm and a rate of at least 100 compressions per minute for adults and children. This depth is crucial for generating adequate blood flow to vital organs during cardiac arrest. Compressions that are too shallow may not effectively circulate blood, which can lead to poor outcomes. The rate of at least 100 compressions per minute is important for maintaining continuous blood flow and keeping up the blood circulation effectively. In the context of CPR, maintaining the appropriate depth and rate becomes critical. Options with inadequate depth, such as 2-3 cm or 3-4 cm, do not provide enough force to circulate blood efficiently. Similarly, a rate of 80 times per minute is below the recommended threshold and would not sustain effective circulation. It's essential to adhere to the updated guidelines to maximize the chances of survival and positive recovery from cardiac events.
