Summary

What Researchers Did

Researchers described the case of a 45-year-old air traffic controller who experienced sudden neurological symptoms after a decompression event during an altitude chamber flight.

What They Found

The patient developed sudden numbness and complete paralysis on his left side, along with speech difficulty and left facial palsy. He was presumptively diagnosed with arterial gas embolism (AGE) and received hyperbaric oxygen therapy (HBOT). After an extended Table VI-A protocol and three additional HBOT sessions (90 minutes of oxygen at 2.0 ATA), all his symptoms completely resolved.

Canadian Relevance

This study covers arterial gas embolism, a Health Canada-recognised indication for hyperbaric oxygen therapy.

Study Limitations

As a single case report, these findings cannot be generalized to all patients experiencing arterial gas embolism.
