What Researchers Did
Researchers conducted an experimental study using nine litters of newborn Wistar rats to investigate the effects of prolonged normobaric and hyperbaric oxygen supplementation on retinal vessels.
What They Found
Rats receiving normobaric oxygen (80% FiO2) for 5 or 10 days developed retinopathy, with the 10-day exposure leading to severe retinopathy and retinal detachment in some cases. In contrast, rats exposed to hyperbaric oxygen (1.80 atm, 80% FiO2) for 10 days showed no evidence of peripheral retinopathy.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A primary limitation is that this experimental study was conducted on newborn rats, meaning its findings may not directly translate to human infants.
