What Researchers Did
This review article summarized the causes, manifestations, and hyperbaric oxygen treatment for arterial and venous gas embolism.
What They Found
Arterial gas embolism (AGE) typically presents with strokelike manifestations, including impaired consciousness, confusion, seizures, and focal neurological deficits. While small amounts of venous gas embolism (VGE) are often tolerated, larger amounts can lead to pulmonary edema, cardiac "vapor lock," or secondary AGE. Treatment for AGE is similar to decompression sickness, beginning with first aid oxygen followed by hyperbaric oxygen therapy.
What This Means for Canadian Patients
Canadian patients experiencing symptoms of gas embolism, such as after diving or surgery, should seek immediate medical attention. Prompt administration of first aid oxygen and subsequent hyperbaric oxygen therapy is crucial for improving outcomes in cases of arterial gas embolism.

Study Limitations
As a review article, this study synthesizes existing literature rather than presenting new primary research data.
