Aka: Air Embolism, Air Embolus, Gas Embolism, Gas Embolus, Vascular Air Embolism
  1. See Also
    1. Venous Thromboembolism
    2. Arterial Gas Embolism (Scuba Diving Injury)
    3. Amniotic Fluid Embolism
  2. Definitions
    1. Air Embolism
      1. Rare but catastrophic obstruction of blood vessels due to introduction of air or gas into the venous circulation
  3. Causes
    1. Central venous catheterization (may occur in up to 0.2% to 1%)
      1. More common with head and neck procedures
    2. Cardiac bypass
    3. Blunt or Penetrating Trauma
    4. Scuba Diving Injury (see Arterial Gas Embolism)
    5. Child birth
    6. Hemodialysis Emergency
  4. Findings
    1. Specific to site of embolism-related obstruction
    2. Pulmonary Air Embolism
      1. Presents similarly to Pulmonary Embolism (e.g. Chest Pain, Dyspnea)
    3. Cardiac Findings
      1. "Millwheel" Heart Murmur may be present
    4. Cerebral Air Embolism
      1. Altered Mental Status
      2. Focal Neurologic Deficits
      3. Seizure
  5. Management
    1. ABC Management
    2. Apply 100% FIO2 to facilitate dissolving air in blood
    3. Consider early hyperbaric chamber (within 6 hours)
    4. Place patient in trendelenburg and left lateral recombent position (Durant's Maneuver)
      1. Postulated to keep air in right atrial apex and prevent passage into pulmonary circulation
    5. Advance central venous line into the right heart and ventricular outflow and attempt to aspirate air
  6. Prevention: Central Lines
    1. Flush Central Lines to remove air
    2. Apply Occlusive Dressing when changing Central Lines
    3. Patient should perform Valsalva Maneuver when the line is being removed
    4. Confirm caps on all intravenous lines
    5. Clamp any Central Line that is leaking

Air Embolism (C0013926)

Definition (NCI_FDA) The presence of bubbles of gas in the vascular system; occurrence is related to the entry of air into the venous circulation following trauma or surgery.
Definition (NCI) The presence of bubbles of gas in the vascular system; occurrence is related to the entry of air into the venous circulation following trauma or surgery.
Definition (CSP) embolism due to air bubbles entering the blood vessels after trauma, surgical procedures, or changes in atmospheric pressure.
Definition (MSH) Blocking of a blood vessel by air bubbles that enter the circulatory system, usually after TRAUMA; surgical procedures, or changes in atmospheric pressure.
