When an air or gas embolism is suspected in the systemic venous circulation, echocardiography should be used to confirm its presence. Prevention: All air should be purged from the tubing of all IV administration sets before hookup and when solution bags or bottles are changed; air elimination filters should be used close to the patient; infusion devices with air detection capability should be used, as well as locking tubing, locking connection devices, or taped connections. Gas emboli are caused by rapid changes in environmental pressure that could happen when flying or scuba diving. Risks for it include genetic predisposition, recent limb or pelvic fracture, burns, surgery (esp. Its incidence after pulmonary embolism and associated risk factors are not well documented.

Arterial blood gas measurements are sometimes helpful but, alone, they are not diagnostic for pulmonary embolism. For people who can't take anticoagulants and in some other cases, surgery may be needed to insert a device that filters blood returning to the heart and lungs. Diagnosis is challenging because symptoms are nonspecific and often misinterpreted and may mimic other diseases of the limbs, abdomen, or chest.

Pulmonary angiography is a radiographic test that involves injection of a radio contrast agent to show the pulmonary arteries. Embolism due to injected drugs, debris, or talc, often resulting in pulmonary infarction. The combination of graduated compression stockings and low-dose heparin is significantly more effective than low-dose heparin alone. Chest radiograph reports are reviewed for evidence of mottled lung fields and right ventricular dilation, and the patient's electrocardiogram is checked for large S waves in lead I, large Q waves in lead III, and right axis deviation. Less than 10% of patients who die from a pulmonary embolism were diagnosed with the condition. pulmonary embolism (PE) obstruction of the pulmonary artery or one of its branches by an embolus. A contrast solution is injected into a foot vein through a catheter. 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 cuffs are connected to a pump that inflates and deflates, mimicking the heart's normal pumping action and reducing the pooling of blood.
