Definition and Causes

Barotrauma is an illness caused by a change in pressure between the environment and the hollow parts of the body, like the lungs, sinuses, and ears. It can be caused by high-altitude climbing, air travel, diving, or hyperbaric oxygen therapy.

There are four types of barotrauma:

Symptoms vary from ear popping and vertigo to organ damage and death.

To avoid barotrauma, take proper acclimatization measures, use dive tables or computers to calculate depth, and make gradual ascents and descents. If you have symptoms, get medical help right away. Treatment may include off-gassing or a hyperbaric chamber. Severe cases must be managed by an interprofessional team.

It is important to stay aware of barotrauma and take steps to prevent it.

Symptoms and Effects on the Body

Barotrauma is the term for bodily damage caused by pressure changes in air or water when diving. Three common types are pulmonary, ear, and mask barotrauma. High-altitude diving can bring on decompression sickness or hypoxia due to a greater pressure change.

Signs of barotrauma while diving or spearfishing include chest pain, bloody nose, and facial pain. Pulmonary barotrauma has extra effects such as breathing difficulty, coughing up pink mucus, and shortness of breath. Bloodshot eyes can also come from the increased pressure underwater.

Dive computers help divers know their nitrogen load and equivalent depth, preventing barotrauma. Equalizing ears and mask and using a quality face mask are musts to stop ear and mask barotrauma.

For emergencies, decompression must be done right away to avoid decompression illness. Barotrauma can also cause intestinal distress, so eating a big meal or drinking alcohol before diving should be avoided.

High-altitude diving/spearfishing must be prepared for, and signs of barotrauma watched out for. Emergency help should be sought if needed.

Factors that Affect Diving in High Altitudes

When it comes to diving and spearfishing, the impact of high altitude should not be underestimated.
