arterial gas embolism

A bolus of gas or air within the blood vessels, which may be caused by overinflation of the lungs.
 
Aetiology
Traumatic chest injury; secondary to distension and barotraumatic rupture of alveoli due to trapped gases in scuba divers (due to too rapid an ascent to the surface); mechanical ventilation; placement of a central venous catheter; cardiothoracic surgery; haemodialysis; orogenital sex during pregnancy.
 
Management
Hyperbaric O2. In scuba divers with arterial gas embolism, creatine kinase levels increased and correlate well with eventual neurologic outcome.
