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 ...
Pulmonary embolism; A lung illustration depicting a pulmonary embolism as a thrombus (blood clot) that has travelled from another region of the body, causes occlusion of the pulmonary bronchial artery, leading to arterial thrombosis of the superior and inferior lobes in the left lung: Specialty: Hematology, cardiology, pulmonology, Emergency ...
An embolism is the lodging of an embolus, a blockage-causing piece of material, inside a blood vessel. [1] The embolus may be a blood clot , a fat globule (fat embolism), a bubble of air or other gas (gas embolism), amniotic fluid (amniotic fluid embolism), or foreign material. An embolism can cause partial or total blockage of blood flow in ...
Pulmonary embolism is the third leading cause of death from cardiovascular disease and happens when blood clots block an artery in the lungs, so blood and gas cannot flow normally.
Impaired arterial blood gas (oxygen) tensions during intense exercise, increased blood lactate, and rarely death have been noted (likely due to ruptured chordae tendinae or a different mechanism of lung hemorrhage). Epistaxis is diagnosed when blood is visible at either or both nostrils during or following exercise.
Mitral stenosis poses a high risk of forming emboli which may travel to the brain and cause stroke. [2] Endocarditis increases the risk for thromboembolism, [2] by a mixture of the factors above. Atherosclerosis in the aorta and other large blood vessels is a common risk factor, [2] both for thromboembolism and cholesterol embolism.
The onset of pulmonary hemorrhage is characterized by a cough productive of blood and worsening of oxygenation leading to cyanosis. [1] Treatment should be immediate and should include tracheal suction, oxygen, positive pressure ventilation, and correction of underlying abnormalities such as disorders of coagulation.
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 ...
