• A venous air embolism occurs when atmospheric gas reaches the systemic venous system, usually a complication of invasive medical procedures, both diagnostic and therapeutic, with potentially severe consequences. (symptoma.com)
  • Venous air embolism may be difficult to diagnose and requires a high level of suspicion because it may mimic other conditions [1] [2]. (symptoma.com)
  • The gas bubble disease is a result of an over-saturation of nitrogen or other gases in the body tissues caused by a supersaturation of gases in the water. (wikipedia.org)
  • This will cause nitrogen excess to be dissolved into the body tissues and the gas bubbles will eventually disappear. (wikipedia.org)
  • Inner ear decompression sickness , (IEDCS) or audiovestibular decompression sickness is a medical condition of the inner ear caused by the formation of gas bubbles in the tissues or blood vessels of the inner ear. (wikipedia.org)
  • DCS results from bubbles in body tissues causing local damage. (dan.org)
  • Instead, it separates out of your blood and forms bubbles in your tissues or blood. (harvard.edu)
  • During ascent, bubbles increase in size and are released by tissues into the veins. (xray-mag.com)
  • When bubbles arise or become trapped in tissues or vessels they begin to cause traumatic injury to the body, which is known as decompression sickness. (xray-mag.com)
  • The release of nitrogen bubbles into blood or tissues can result in obstruction of blood flow or pressure effects. (cdc.gov)
  • Decompression sickness is a disorder in which nitrogen dissolved in the blood and tissues by high pressure forms bubbles as pressure decreases. (merckmanuals.com)
  • As outside pressure decreases during ascent from a dive or when leaving a compressed air environment, the accumulated nitrogen that cannot be exhaled immediately forms bubbles in the blood and tissues. (merckmanuals.com)
  • Nitrogen bubbles may form in small blood vessels or in the tissues themselves. (merckmanuals.com)
  • AGE occurs when bubbles enter arterial circulation, traveling through the arteries and potentially causing tissue damage by blocking blood flow at the small vessel level. (dan.org)
  • This injury, called pulmonary barotrauma, involves release of gas bubbles into the arterial circulation. (dan.org)
  • Air can enter the arterial circulation and result in an arterial gas embolism (AGE), which can cause a rapid onset of stroke like symptoms. (xray-mag.com)
  • Bubbles are introduced into the arterial circulation where they can cause multifocal ischemia, and may occur after diving related, iatrogenic, or accidental pulmonary barotrauma or by direct iatrogenic introduction of gas into the vasculature. (standardofcare.com)
  • In divers there is the risk of paradoxical embolism of gas bubbles (passage of bubbles into the arterial circulation) which occur in just about all divers in the venous circulation during decompression. (scuba-doc.com)
  • In addition, a Valsalva maneuver , used by most divers to equalize their ears during descents and ascents, can increase venous atrial pressure to the point that it forces blood containing bubbles across the PFO into the arterial circulation. (scuba-doc.com)
  • However, other conditions characterized by bubbles entering the arterial circulation, such as open-chamber cardiac surgery, do not produce inner-ear involvement, while sometimes damaging the brain extensively. (who.int)
  • Background Cerebral infarctions resulting from iatrogenic air embolism (AE), mainly caused by small air bubbles, are a well-known and often overlooked event in endovascular interventions. (bmj.com)
  • Conclusion In iatrogenic AE, the size of the bubbles can have a major impact on the number and total volume of cerebral infarctions. (bmj.com)
  • Cerebral infarctions caused by iatrogenic air embolism during endovascular interventions are a known risk, but the underlying pathophysiology remains largely unclear. (bmj.com)
  • Complications include arterial bleeding, intra-arterial infusion of fluids and drugs via pressurized fluid bags, or embolism of arterial plaques/air bubbles with subsequent cerebral injury. (ispub.com)
  • Cerebral air embolism is rare but can be fatal. (radiopaedia.org)
  • Cerebral air embolism can be within the arterial or venous systems. (radiopaedia.org)

  • Less commonly, material other than blood clots can block blood flow, including fat, collagen or other tissue, and air bubbles. (radiologyinfo.org)
  • This prevents an embolism, or air bubble, from entering the tissue inside the cutting. (fifthseasongardening.com)
  • In addition, its easy-to-use gel texture quickly heals plant tissue, avoiding both infections and embolisms caused by air bubbles. (alchimiaweb.com)
  • These bubbles may expand and injure tissue, or they may block blood vessels in many organs-either directly or by triggering small blood clots. (merckmanuals.com)
  • At various intervals following the dives the divers were checked with Doppler ultrasound devices, and the group that had a faster ascent rate was shown to have higher bubble grades. (xray-mag.com)
  • Faster ascent rates are thought to have an impact on decompression stress by not allowing sufficient gas bubbles to be off-gassed through breathing. (xray-mag.com)

  • The GBD model consisted of exposing fish to supersaturation in water with approximately 170% total dissolved gas (TDG) for 18 hours, producing severe gas embolism . (bvsalud.org)
  • Previous reports show a high association of inner-ear DCS with persistent foramen ovale (PFO), suggesting that a moderate-to-severe right-to-left shunt might represent a major predisposing factor, and more properly de fi ning it as an event from arterial gas embolism (AGE). (who.int)
  • A PFO was demonstrated by transthoracic and transesophageal bubbles echocardiogram, and a large, mobile and complex thrombus was attached to the PFO and mobilized through the left ventricle. (longdom.org)
  • This redundancy of major veins, the researchers say, protects the leaves from the effects of embolism -- bubbles that form in their "water pipes" during drought -- because it provides alternate routes for water to flow around vein blockages. (sciencedaily.com)
  • Even with strong drought that forms embolism in the veins, a small leaf maintains function in its vein system and can keep functioning for water transport," Sack said. (sciencedaily.com)
  • Since the brain receives the highest proportion of blood flow, it is the main organ in which bubbles may interrupt circulation if they become lodged in small arteries. (dan.org)
  • An opening in the heart can also allow a relatively large air bubble (called an air embolism) to circulate into your arteries. (harvard.edu)
  • Brain effects after bubble induced ischemia are similar to a stroke, including excitatory neurotransmitter release, oxidative oxidative stress, inflammation, and an immune response. (standardofcare.com)

  • The gas bubble disease can be detected by the formation of small gas bubbles under the epidermis which includes the formation of gas bubbles in the skin, the gills and eyeballs causing exophtalmia. (wikipedia.org)
  • Small gas bubbles in fish can be prevented and somewhat cured by relocating fish into deep water that contains higher pressures and therefore a higher amount of gases can be dissolved in the water. (wikipedia.org)
  • [8] DCS and arterial gas embolism are treated very similarly because they are both the result of gas bubbles in the body. (wikipedia.org)
  • Moreover, in other sites, such as the spinal cord, the prevailing mechanism for DCS is not AGE, but more likely local bubble formation with subsequent compression of venules and capillaries. (who.int)
