CPR, an emergency technique combining chest compressions and rescue breaths, is primarily performed in which situation?

Explanation

CPR, or cardiopulmonary resuscitation, is an emergency technique combining rhythmic chest compressions with rescue breaths, performed when a person’s heart has stopped beating effectively or they have stopped breathing, such as during sudden cardiac arrest. The technique aims to manually help maintain some blood circulation and oxygen delivery to vital organs, particularly the brain, until more advanced emergency medical treatment can be provided. Because performing CPR correctly and safely requires proper training, many organizations offer certified courses to teach this potentially life-saving technique to members of the public.
