Prior to Knowledge Development Presentation Two and Rescue Training Session Two, the PADI Rescue Diver course student diver must successfully complete a sanctioned course in Cardiopulmonary Resuscitation (CPR-Primary Care) and basic first aid (Secondary Care) within the past two years (24 months).

The Emergency First Response Primary Care (CPR) and Secondary Care (First Aid) courses are highly recommended and can be used to meet these requirements. Emergency First Response is a basic training program in CPR and emergency care. The PADI Rescue Diver course does not teach either CPR or basic first aid, but applies and builds on these skills as appropriate for dive scenarios.
