BLS 

The American Heart Association Basic Life Support (BLS)  covers core material such as adult and pediatric CPR (including two-rescuer scenarios and use of the bag mask), foreign-body airway obstruction, and automated external defibrillation. Healthcare providers such as EMS personnel, physician assistants, doctors, dentists, nurses, and respiratory therapists must have a credential(card) documenting successful completion of a CPR course. This would also include nursing students, EMT students, and anyone interested in working in the healthcare industry. The BLS class is also intended for federal agents, police officers, and first responders.
