What should be ensured when performing effective CPR?

Minimizing interruptions in compressions is crucial when performing effective CPR because continuous chest compressions help maintain blood circulation to vital organs, particularly the heart and brain. High-quality CPR involves delivering compressions at the correct depth and rate (around 100 to 120 compressions per minute) while ensuring that interruptions, such as those that may occur during rescue breaths or switching rescuers, are as brief as possible. Studies have shown that the longer the chest compressions are interrupted, the less effective CPR becomes, directly affecting the chances of survival for the person in cardiac arrest.

Using a breathing mask can be helpful in providing rescue breaths but is not essential for high-quality CPR, especially if one is not trained or comfortable using it. Offering the person water is not appropriate during CPR as the individual is unconscious or unable to swallow safely. Lastly, performing compressions with one hand is not recommended for adults and children, as two hands are needed to provide sufficient force and depth for effective compressions; one-handed compressions may not generate adequate blood flow.
