What happens if you don’t decompress after a dive?

If a diver surfaces without exhaling, air trapped in the lungs expands with ascent and may rupture lung tissue – called pulmonary barotrauma – which releases gas bubbles into the arterial circulation. This distributes them to body tissues in proportion to the blood flow.
