Abstract： To the Editor:Early bystander cardiopulmonary resuscitation (CPR) is crucial for survival and long-term quality of life of patients with out-of-hospital cardiac arrest.[1]Training schoolchildren how to perform CPR is highly recommended by many countries and health organizations,including the World Health Organization.[2,3]Schoolteachers with previous training are highly suggested as CPR instructors to teach schoolchildren.[4,5] The CPR knowledge and previous training of the teachers are very important for their willingness to teach CPR and the quality of their teaching.[6,7] A 6-year longitudinal study confirmed that teachers who previously attended a 60-min theoretical and practical CPR course could provide adequate resuscitation training in schools.[8] In Belgium,some Flemish primary schoolteachers had a high interest in CPR training and were also willing to teach CPR.[7] In China,little is known about teachers' CPR knowledge and the attitude toward CPR education.The main goal of this study was to evaluate Chinese primary and secondary teachers' current CPR knowledge,previous training,and the attitude toward CPR education.
