Ketogenic Food Products for Oxygen Toxicity
Trial Summary
What is the purpose of this trial?
The purpose of this study is to understand how ketogenic food products affect oxygen toxicity in undersea divers. Oxygen toxicity affecting the central nervous system, mainly the brain, is a result of breathing higher than normal oxygen levels at elevated pressures as can be seen in SCUBA diving or inside a hyperbaric (pressure) chamber. This is a condition that may cause a wide variety of symptoms such as: vision disturbances, ear-ringing, nausea, twitching, irritability, dizziness, and potentially loss of consciousness or seizure. Because nutritional ketosis has been used to reduce or eliminate seizures in humans, it may be beneficial to reduce oxygen toxicity as well. The investigators hope this study will provide a help to develop practical and useful methods for improving the safety of undersea Navy divers, warfighters and submariners.
