Summary

What Researchers Did

Doctors reported a case of arterial gas embolism during a cardiac cryoablation procedure where they treated the patient using Navy Treatment Tables and also changed his body position mid-treatment to move a trapped air bubble from the heart.

What They Found

US Navy Table 6 reduced the brain air embolism but could not clear air trapped in the tip of the left ventricle. Adding Navy Table 5 with right lateral positioning and manual vibration over the heart successfully resolved all remaining air, confirmed by CT scan. The patient then began rehabilitation.

Canadian Relevance

Arterial gas embolism is a covered OHIP indication for HBOT in Ontario. This case adds practical technique refinements applicable to Canadian centers treating post-procedure AGE.

Study Limitations

This is a single case report and the body-positioning technique described has not been validated in larger studies.
