Clinical Presentation - Air Embolism

Patients with clinically significant air embolism may experience complete circulatory collapse. Cyanosis and petechiae may be observed. Dramatic falls in arterial blood pressure, elevation of central venous pressure (CVP), arrhythmias, and ECG changes may indicate the presence of severe pulmonary air embolism. A characteristic cog wheel or mill wheel murmur may be heard over the precordium.

A patient at risk for air embolism who experiences the above signs and symptoms should be investigated and treated rapidly.
