  2. Air embolism - Wikipedia

    en.wikipedia.org/wiki/Air_embolism

    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 ...

  3. Obstructive shock - Wikipedia

    en.wikipedia.org/wiki/Obstructive_shock

    This swinging of the heart causes electrical alternans seen on EKG. A pericardial effusion is fluid in the pericardial sac. When large enough, the pressure compresses the heart. This causes shock by preventing the heart from filling with blood. This is called cardiac tamponade. The chambers of the heart can collapse from this pressure.

  4. Intestinal ischemia - Wikipedia

    en.wikipedia.org/wiki/Intestinal_ischemia

    The treatment of intestinal ischemia depends on the cause and can be medical or surgical. However, if bowel has become necrotic, the only treatment is surgical removal of the dead segments of bowel. [34] In non-occlusive disease, where there is no blockage of the arteries supplying the bowel, the treatment is medical rather than surgical ...

  5. Pneumomediastinum - Wikipedia

    en.wikipedia.org/wiki/Pneumomediastinum

    The tissues in the mediastinum will slowly resorb the air in the cavity so most pneumomediastinums are treated conservatively. Breathing high flow oxygen will increase the absorption of the air. If the air is under pressure and compressing the heart, a needle may be inserted into the cavity, releasing the air.

  6. Ischemia - Wikipedia

    en.wikipedia.org/wiki/Ischemia

    The signs and symptoms of ischemia vary, as they can occur anywhere in the body and depend on the degree to which blood flow is interrupted. [4] For example, clinical manifestations of acute limb ischemia (which can be summarized as the "six P's") include pain, pallor, pulseless, paresthesia, paralysis, and poikilothermia.

  7. Arterial embolism - Wikipedia

    en.wikipedia.org/wiki/Arterial_embolism

    Arterial embolism can be serious if not treated promptly. [1] [2] Without treatment, it has a 25% to 30% mortality rate. [1] The affected area can be permanently damaged, and up to approximately 25% [1] [2] of cases require amputation of an affected extremity. Arterial emboli may recur even after successful treatment.

  8. Thromboembolism - Wikipedia

    en.wikipedia.org/wiki/Thromboembolism

    Arterial thromboembolism (ATE) is a less common but more severe form of thromboembolism, which can affect various organs, such as the brain, heart, kidneys, limbs, and mesentery. ATE can cause life-threatening conditions, such as stroke, myocardial infarction, acute kidney injury, limb ischemia, and mesenteric ischemia.

  9. Embolization - Wikipedia

    en.wikipedia.org/wiki/Embolization

    Embolization refers to the passage and lodging of an embolus within the bloodstream. It may be of natural origin (pathological), in which sense it is also called embolism, for example a pulmonary embolism; or it may be artificially induced (therapeutic), as a hemostatic treatment for bleeding or as a treatment for some types of cancer by deliberately blocking blood vessels to starve the tumor ...
