ADULT BASIC LIFE SUPPORT (BLS)

Definition

The American Heart Association (AHA) defines adult CPR as appropriate for any person over the age of 8 years old or post-adolescence, which can be identified by:

  • Males: Chest or underarm hair
  • Females: Any breast development

This lesson covers both hands-only CPR for laypersons and full BLS for healthcare providers (HCPs).

Important Notes

  • Hands-only CPR (chest compressions only) is preferred for lay rescuers.
  • HCPs should provide full CPR (compressions + breaths) unless an advanced airway is in place.
