Final answer:
The current standards for CPR recommend chest compressions at a rate of 100 compressions per minute, with a depth of at least 5 cm. It is advised to switch chest compressors every 2 minutes to prevent fatigue.
Step-by-step explanation:
The current standards for chest compressions during CPR call for compressing the chest at least 5 cm deep and at a rate of 100 compressions per minute.
These guidelines are based on the fact that high-quality chest compressions are important for maintaining blood flow to vital organs, especially the brain, to prevent irreversible damage and death of neurons.
It is recommended to switch chest compressors every 2 minutes to avoid fatigue during CPR, as performing continuous chest compressions can be physically demanding.
