Regardless of occupation, BLS should be a known skillset for all. This content guide serves as an instruction manual designed to explain the necessary tools to provide effective BLS, whether in or outside of a hospital setting. When equipped with the right tools, it is possible to perform high-quality BLS and restore normal heart rhythm. The content in this guide favors terminology specific to personnel who routinely care for patients. However, non-medical personnel can also benefit from reading this guide, as cardiac arrests are not confined to hospital settings only. Some of the equipment discussed is not applicable for non-medical personnel, such as a bag-valve mask.
