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 ...

Illustration depicting embolism from detached thrombus. An embolus (/ ˈ ɛ m b ə l ə s /; [1] pl.: emboli; from the Greek ἔμβολος "wedge", "plug") is an unattached mass that travels through the bloodstream and is capable of creating blockages. When an embolus occludes a blood vessel, it is called an embolism or embolic event. [2]
Massive PE causing hemodynamic instability (shock and/or low blood pressure, defined as a systolic blood pressure <90 mmHg or a pressure drop of 40 mmHg for >15 min if not caused by new-onset arrhythmia, hypovolemia, or sepsis) is an indication for thrombolysis, the enzymatic destruction of the clot with medication. In this situation, it is the ...
One complication, air embolism, in which air enters the bloodstream, is potentially fatal, especially when it occurs on the left side of the heart. [5] Air can enter the circulatory system through a damaged vein in the injured chest and can travel to any organ; it is especially deadly in the heart or brain. [5]
Thus, a lung exam is important. Other findings may include decreased chest mobility and air underneath the skin (subcutaneous emphysema). [12] Pulmonary embolism similarly presents with shortness of breath and hypoxia. Chest pain worse with inspiration is frequently seen. Chest pain can also be similar to a heart attack.
In cases of hemothorax complicating pulmonary embolism treatment, the hemothorax is usually on the side of the original embolism. [6] Those with an abnormal accumulation of air within the pleural space (a pneumothorax) can bleed into the cavity, which occurs in about 5% of cases of spontaneous pneumothorax, [8] especially when lung bullae ...
