Certified Hyperbaric Technologist Practice Test 2026 – Comprehensive Exam Prep

In the case of mediastinal emphysema, hyperbaric oxygen therapy is particularly indicated when arterial gas embolism (AGE) is present. AGE can occur when gas from the lungs leaks into the bloodstream and travels to the arterial system, potentially causing life-threatening complications. The hyperbaric environment increases the partial pressure of oxygen, which helps to reduce the size of the bubbles formed by the gas embolism and improve oxygen delivery to the tissues. This approach is crucial because untreated AGE can lead to serious neurological damage or other systemic effects.

Routine check-ups, the development of pneumonia symptoms, or merely following a primary care physician's recommendation without the indication of AGE do not meet the urgent criteria for hyperbaric treatment for this condition. Therefore, being addressed solely in the context of AGE illustrates the critical decision-making process required in patient management for mediastinal emphysema situations.
