The application has been designed taking into account some of the specific characteristics of SCA cases during contact sports, such as football, like taking special care of the cervical spine when handling the player. CPR 11 is a guide that may be very useful for anyone (players, coaches, referees, relatives, spectators, etc) attending sports events of any level. It is not a substitute for proper training in cardiopulmonary resuscitation (CPR). We recommend everyone to receive formal instruction in CPR and AED use.
