Air may enter a vessel postoperatively, during intravenous injections, after failure to purge intravenous lines, or as a result of rupture of a central line balloon. Positive and end-expiratory pressure may be used to keep functional alveoli inflated to improve functional reserve capacity. An embolism is an obstruction in a blood vessel due to a blood clot or other foreign matter that gets stuck while traveling through the bloodstream. The treatment for the syndrome is nonspecific: good general supportive care of fluid balance, vital signs, oxygenation, electrolytes, and hemodynamics. Symptoms of a PE may include shortness of breath, chest pain particularly upon breathing in, and coughing up blood. Embolism can be prevented in high risk patients through antithrombotic drugs such as heparin, venous interruption, gradient elastic stockings, and intermittent pneumatic compression of the legs. Pulmonary angiography is usually performed in a hospital's radiology department and takes 30-60 minutes. NOTE: A very small amount of air in a vessel or intravenous tubing is not hazardous. Intermittent pneumatic compression involves wrapping knee- or thigh-high cuffs around the legs to prevent blood clots. In cases of an undiagnosed pulmonary embolism, about 30% of patients die.

Embolism of the pulmonary artery or one of its branches, usually caused by an embolus from a blood clot in a lower extremity. The test takes about 10 minutes. When a pulmonary embolism is suspected, evaluation includes oximetry, chest x-ray, blood tests for D-dimer, and, depending on local hospital practices, duplex venous ultrasonography of the legs, ventilation/perfusion scanning, or multidetector CT angiography of the chest. The patient should be immediately repositioned with the right atrium above the gas entry site, so that air will be trapped there and not move into the pulmonary circulation or the right heart. The combination of graduated compression stockings and low-dose heparin is significantly more effective than low-dose heparin alone. Venography takes between 30-45 minutes and can be done in a physician's office, a laboratory, or a hospital.

In most cases, pulmonary embolism is caused by blood clots that travel to the lungs from the legs or, rarely, other parts of the body (deep vein thrombosis). An electrocardiograph shows the heart's electrical activity and helps distinguish a pulmonary embolism from a heart attack. An. Information and translations of embolism in the most comprehensive dictionary definitions resource on the web. Arterial blood gas measurements are sometimes helpful but, alone, they are not diagnostic for pulmonary embolism. The outcome for all other patients is generally good; only 3% of patients die who are properly diagnosed early and treated. A central venous catheter should be placed into the central venous circulation and any gas bubbles and air aspirated from the catheter. A normal result essentially rules out a pulmonary embolism. Symptoms of a blood clot in the leg may also be present, such as a red, warm, swollen, and painful leg.
