To help CPR practitioners to remember the order of the procedural steps, the acronym ABC was taught to stand for Airway, Breathing, Circulation. In 2010, the order of the steps was changed to Circulation, Airway, Breathing, so the acronym is now CAB.
The Itching is usually due to a disturbance in the skin of the external auditory canal. Ear canal skin is very sensitive. The slightest accumulation of debris, even a dead hair, may be felt as an itching sensation. Often, dryness in the ear is what causes inner ear itching.
In most of these cases, the itch is also accompanied by watery and irritated eyes. Occasionally, irritation as well as itching of the ear canals can be cause by sensitivity to certain shampoo or hairsprays. Another one of the causes of ear canal itching is also the insufficient development of wax of the ear. This is a very common condition in swimmers. But, even an excessive production or buildup of wax of the ear can cause the ear canal to itch.
