Air contains only about 60% oxygen. When someone is having difficulty breathing, there is ususally a heart or lung condition. As the heart pumps, it allows for and exchange of co2 and o2. When there is a dysfunction, the person cannot pull out all of the o2 from the air and need 100% o2 in order to have levels that are able to sustain life.
