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.
What This Means for Canadian Patients
This case highlights that HBOT can be an effective treatment for severe neurological symptoms caused by arterial gas embolism. For Canadian patients experiencing similar sudden neurological issues after pressure changes, this suggests that prompt diagnosis and HBOT could lead to full recovery.
Canadian Relevance
This study covers arterial gas embolism, a Health Canada-recognized indication for hyperbaric oxygen therapy.
Study Limitations
As a single case report, these findings cannot be generalized to all patients experiencing arterial gas embolism.
