 The study found that black children have more than a four-fold higher risk of out-of-hospital cardiac arrest than white and Hispanic children, and they are also 26% less likely to survive than white and Hispanic children. Dr. Cody Gathers of Children's Hospital of Philadelphia led the study. CPR is an important determinant in cardiac arrest survival, and black children do not receive CPR after cardiac arrest as frequently and have much lower rates of survival after cardiac arrest.
