Equalization Problems
Pressure equalized as the diver goes deeper in the water. If these airway spaces cannot equalize then it will be impossible for any diving activity to be performed. Chronic rhinitis, nasal septal deviations, colds and other factors, such as allergies, could affect the whole otorhinolaryngological system thus causing inconvenience and dizziness to the diver as well as injuries associated with exposure to pressure, such as barotraumas or eardrum damages.
What is certain is that a dive cannot be performed without having pressure equalized. When a diver has a cold or suffers from allergies and mucus block the nasal area he or she should not get into the water for any reason. The same thing applies to chronic problems such as the narrow nasal passage and the nasal septal deviation. Persistence and stress induced by repetitive efforts could lead to injuries of these vulnerable areas.
A simple method for “conserving” the ear-nose system is the regular nasal and ear irrigation with physiological saline, so as to remove unwanted mucus and bacteria, while the inner ear and nasal passages remain moistened. As far as the rest parts of both ear and nose are concerned, hyperbaric medicine specialists will be able to find solutions, which may also include a surgery
