Early CPR is a vital link within the Chain of Survival. throughout cardiopulmonary arrest, the heart quivers and twitches, and can't pump blood effectively through the body. CPR keeps blood flowing through the body, sustaining life till a defibrillator, or alternative advanced treatment, arrives.
CPR is composed of 2 basic activities:
Rescue breaths - either mouth-to-mouth or mouth-to-mask breaths
An SCA victim's likelihood of survival doubles if CPR happens before medical services arrives. In some communities,
911 medical dispatchers are trained to advise on instructions over the phone, but this is less than ideal. That's why it's very important that the people in your community understand CPR and may act quickly in an emergency.
