Gas embolism is a diving disorder experienced by underwater divers who breathe gases at ambient pressure, and can happen in two distinct ways: . Pulmonary barotrauma: Air bubbles can enter the bloodstream as a result of gross trauma to the lining of the lung following a rapid ascent while holding the breath; the air held within the lung expands to the point where the tissues tear (pulmonary ...
Chest pain in children is usually evaluated in the emergency departments. It can be distressing for parents and children. Pediatric chest pain differs from chest pain in adults because it is most often unrelated to the heart. [2] The causes of pediatric chest pain vary according to the organ or tissue in the child. that generates the pain.
The air may then enter the arterial circulation producing arterial gas embolism (AGE), with effects similar to severe decompression sickness. [7] Although AGE may occur as a result of other causes, it is most often secondary to PBT. AGE is the second most common cause of death while diving (drowning being the most common stated cause of death ...
DCS often causes air bubbles to settle in major joints like knees or elbows, causing individuals to bend over in excruciating pain, hence its common name, the bends. Individual susceptibility can vary from day to day, and different individuals under the same conditions may be affected differently or not at all.

Causes include pulmonary embolism, cardiac tamponade, and tension pneumothorax. [3] These are all life-threatening. Symptoms may include shortness of breath, weakness, or altered mental status. Low blood pressure and tachycardia are often seen in shock. Other symptoms depend on the underlying cause. [4]
Depressurisation causes inert gases, which were dissolved under higher pressure, to come out of physical solution and form gas bubbles within the body. These bubbles produce the symptoms of decompression sickness. [6] [7] Bubbles may form whenever the body experiences a reduction in pressure, but not all bubbles result in DCS. [8]
