Can you die from diving too deep?

Why is diving too deep dangerous?

As you descend, water pressure increases, and the volume of air in your body decreases. This can cause problems such as sinus pain or a ruptured eardrum. As you ascend, water pressure decreases, and the air in your lungs expands. This can make the air sacs in your lungs rupture and make it hard for you to breathe.

Can your lungs collapse from diving?

If a diver experiences a pneumothorax while underwater at any considerable depth, it could be fatal. Collapsed lungs that occur for specific reasons, such as trauma or with medical procedures near the lung, are not disquali- fying but require a considerable time of healing before diving.

At what depth will your lungs collapse?

If one descends to a depth of 100 feet (about 30 metres), the lung shrinks to about one-fourth its size at the surface. Excessive compression of the lungs in this manner causes tightness and pain in the thoracic cavity.

Can pneumothorax be cured?
