Immediate Management of Suspected Air Embolism

Clinical Recognition and Assessment

• The European Heart Journal recommends assessing patients with suspected air embolism for respiratory symptoms, including tachypnea, dyspnea, cyanosis, and hypoxemia, as well as cardiovascular signs such as hypotension, tachycardia, jugular venous distension, and new heart murmurs 1
• The European Heart Journal also suggests assessing for neurological manifestations, including altered mental status, seizures, or focal neurological deficits, which may indicate cerebral air embolism 1

Emergency Management Protocol

• The European Heart Journal recommends administering fluid resuscitation to increase central venous pressure and preparing vasopressors for hypotension management in patients with suspected air embolism 1
• Praxis Medical Insights recommends initiating CPR if cardiac arrest occurs in hemodynamically unstable patients with suspected air embolism 2

Monitoring and Further Assessment

• The European Heart Journal recommends using pulse oximetry and arterial blood gas analysis to assess oxygenation in patients with suspected air embolism 1

Management of Suspected Air Embolism

Emergency Management Protocol

• The American College of Obstetricians and Gynecologists recommends positioning the patient in the left lateral decubitus position to prevent air from migrating to the pulmonary artery 3
• Administering normobaric 100% oxygen can reduce the size of air bubbles and improve tissue oxygenation, as suggested by the American College of Obstetricians and Gynecologists 3
• If a central venous catheter is in place, attempting to aspirate air bubbles from the right atrium is recommended by the American College of Obstetricians and Gynecologists 3
• For arterial air embolism with neurological symptoms, considering hyperbaric oxygen therapy (HBOT) if available is suggested by the American College of Obstetricians and Gynecologists 3
