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 ...
If large amounts of air leak into the tissues around the head, the face can swell considerably. [8] In cases of subcutaneous emphysema around the neck, there may be a feeling of fullness in the neck, and the sound of the voice may change. [10] If SCE is particularly extreme around the neck and chest, the swelling can interfere with breathing.
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 ...
Deep pain at the back of the hip. Pain near the rear of your hip could be a sign of sciatica, a ligament injury, or one of the numerous small muscles on the back outer portion of your hip socket ...
When there is dysfunction at this transitional joint, it can cause referred pain to the lower back, hip, abdominal, and/or groin/testicular/labia area, Dr. Megan Daley, PT, DPT, Cert Dn, CF-L1 ...
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. [17] [52] Bubbles may form whenever the body experiences a reduction in pressure, but not all bubbles result in DCS. [53]
Suggested causes included: Cavitation within the joint—small cavities of partial vacuum form in the synovial fluid and then rapidly collapse, producing a sharp sound. [5] [6] Rapid stretching of ligaments. [7] Intra-articular (within-joint) adhesions being broken. [7] Formation of bubbles of joint air as the joint is expanded. [8]
Pneumoperitoneum is pneumatosis (abnormal presence of air or other gas) in the peritoneal cavity, a potential space within the abdominal cavity.The most common cause is a perforated abdominal organ, generally from a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma.
