Divers are at risk for barotrauma, a hazard associated with the pressure of water affecting body tissue. This accident is the cause of the mismatch between the external pressure and the internal pressure of the human body.

Danger of pressure

The deeper the water, the higher the pressure because the air is compressed on the surface of the water. A sudden change in depth can cause internal damage to swimmers and divers because the pressure exerted on the organs that contain air becomes too great.

Signs of barotrauma

– Pain in the place of air compression;

– Bloodshot eyes.

What should be done ?

– Advise the victim to see a doctor;

– Call for help if the situation is alarming;

– Assess his vital signs.

Danger of air bubbles

The pressure can create air bubbles in the blood vessels of the deep water swimmer. When the diver rises to the surface, the bubbles can increase and cause several dangerous ailments such as a pulmonary embolism (= sudden obstruction of a blood vessel) or the expansion of the lungs (= increase in volume of the organ).

What are the risks ?

– The level of consciousness may be altered;

– Cough and shortness of breath;

– Generalized or localized pain;

– Skin rash ;

— Convulsions ;

– Weakness ;

– Paralysis or impairment of vision.

How to react ?

– Call for help;

– Place the victim in the lateral safety position;

– Assess his vital signs.
