First aid and CPR are both taken in emergencies to save lives. CPR is specific while first aid is a broad practice encompassing CPR among other lifesaving skills. CPR and first aid training are available to interested persons through institutions of choice mostly through online certification programs. These two are crucial skills and knowledge as they can make a difference between life and death.
In CPR, the victim is usually unconscious and without a detectable pulse. A person receiving CPR can hardly perform it on themselves. The same doesn’t always apply to persons receiving first aid. Persons can deliver first aid to themselves — some of the cases of first aid demand for the participation of the victim. The victim is, at times, given instructions on how to act.
