The BLS process for adults emphasizes one-rescuer CPR and recognizes that often there may be more rescuers available to help.
In the BLS course, students learn both one- and two-rescuer CPR. The steps for BLS for adults will depend on the training and number of rescuers available. Any layperson can perform CPR, but as the proficiency and number of team members increase, the process changes.
