Systemic air embolism is a dramatic event frequently resulting in death. Th
e clinical manifestations are polymorphic and unspecific. We report a case
of a systemic air embolism in a patient with lung contusion. We wish to aro
use a sensibility for this clinical picture,which seems to be underestimate
d in its frequency and importance, and discuss concepts of mechanical venti
lation in patients with blunt thoracic trauma.
