A basic requirement for survival is oxygen. The air we inhale contains around 21% oxygen. Certain ailments might cause the body to take in less oxygen, or convey less oxygen to the organs and tissues. Providing supplemental oxygen at a higher concentration than ambient air during an emergency may delay damage to vital organs and permit greater oxygen absorption into the bloodstream.

The primary goals of using emergency oxygen are to reduce heart workload and correct mild to moderate hypoxia (insufficient oxygen delivery to organs and tissues). Rules for the treatment of hypoxia might contrast between medical aid suppliers and experts. If the guidelines of your local EMS authority or Medical Director differ from those of this training, follow them. When providing medical care to a patient, you should always take standard or universal precautions in accordance with OSHA and workplace regulations.
