What Researchers Did
Researchers reviewed medical records from 233 cases of altitude chamber decompression sickness to see if treatment delay affected recovery.
What They Found
They found a direct link between how long treatment was delayed and how well patients recovered. Patients who were successfully treated with a single hyperbaric oxygen therapy session had an average delay of 10.6 hours, while those who failed treatment or had symptoms return had an average delay of 18.2 hours. This difference was statistically significant.
What This Means for Canadian Patients
For Canadian patients experiencing decompression sickness, these findings suggest that seeking hyperbaric oxygen therapy as quickly as possible is crucial for a better chance of recovery. A longer delay in starting treatment may lead to a less successful outcome or a return of symptoms.
Canadian Relevance
This study covers decompression sickness, which is a Health Canada-recognized indication for hyperbaric oxygen therapy.
Study Limitations
This study was a retrospective review of military records from a specific time period, which may limit its generalizability to all patient populations today.
