What is the most serious diving emergency?
Serious medical conditions can occur as the result of pulmonary barotrauma including: mediastinal emphysema, subcutaneous emphysema, pneumothorax and arterial gas embolism. This is why the number one rule of scuba diving is to breathe continuously and never hold your breath!
What are diving emergencies?
The four main pathologies in diving medicine include: barotrauma (sinus, otic, and pulmonary); decompression illness (DCI); pulmonary edema and pharmacological; and toxic effects of increased partial pressures of gases. The clinical manifestations of a diving injury may be seen during a dive or up to 24 h after it.
What is the most common injury in scuba diving?
The most common injury in divers is ear barotrauma (Box 3-03). On descent, failure to equalize pressure changes within the middle ear space creates a pressure gradient across the eardrum.
Is scuba diving hard on your body?
Scuba diving exposes you to many effects, including immersion, cold, hyperbaric gases, elevated breathing pressure, exercise and stress, as well as a postdive risk of gas bubbles circulating in your blood. Your heart’s capacity to support an elevated blood output decreases with age and with disease.
What’s decompression sickness?
Decompression sickness is a disorder in which nitrogen dissolved in the blood and tissues by high pressure forms bubbles as pressure decreases. Symptoms can include fatigue and pain in muscles and joints.

Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. … But if a diver rises too quickly, the nitrogen forms bubbles in the body. This can cause tissue and nerve damage. In extreme cases, it can cause paralysis or death if the bubbles are in the brain.
