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.
You are more likely to get otitis externa because liquid in your ear canal can make you more likely to develop an infection. Water can wash away ear wax inside your ears making them itchy. If you scratch inside your ears, the skin can become damaged, making the external canal more vulnerable to infection.
