  1. Read the article by Mirski et al.  entitled “Diagnosis and treatment of vascular air embolism” on page 164 of this issue.

  2. Review the questions and other required information for CME program completion (published in both the print and online journal).

  3. When ready, go to the CME Web site: . Submit your answers, form of payment, and other required information by December 31 of the year following the year of publication.

The American Society of Anesthesiologists is approved by the Accreditation Council for Continuing Medical Education (ACCME) to sponsor continuing medical education programs for physicians.
The American Society of Anesthesiologists designates this educational activity for a maximum of 1 AMA PRA Category 1 Credit™  . Physicians should only claim credit commensurate with the extent of their participation in the activity.
Purpose:  The focus of the journal-based CME program, and the articles chosen for the program, is to educate readers on current developments in the science and clinical practice of the specialty of Anesthesiology.
Target Audience:  Physicians and other medical professionals whose medical specialty is the practice of anesthesia.
Learning Objectives:  After reading this article, participants should have a better understanding of the diagnosis and management of vascular air embolism.
