In Basic Life Support (BLS), what is the recommended rate of chest compressions for an adult?

The recommended rate of chest compressions for an adult in Basic Life Support (BLS) is 100-120 compressions per minute. This rate is critical for maintaining adequate blood flow during cardiac arrest and ensuring effective resuscitation.

Compressions at this rate help to sustain circulation of oxygenated blood to vital organs, which is essential in increasing the chances of survival. Compressing too slowly may not generate sufficient pressure to circulate blood, while compressing too quickly may reduce the effectiveness of each compression.

Using this guideline of 100-120 compressions per minute is based on extensive research and retraining protocols established by organizations like the Resuscitation Council UK and the American Heart Association. These recommendations are adjusted periodically based on new evidence to ensure the highest chance of success in resuscitation efforts.

Other response options either fall below the recommended rate or exceed it, thus compromising the effectiveness of the intervention.
