Barbara Shykoff earned her B.A.SC. (Engineering Science, Chemical option) from University of Toronto, her M.Sc.E (Bioengineering Institute) from the University of New Brunswick, and her Ph.D. (Biomedical Engineering Unit) from McGill University. For the last 16 years she has worked at the U.S. Navy Experimental Diving Unit. Her principal areas of investigation have been pulmonary oxygen toxicity, some other aspects of prolonged mildly-hyperoxic exposure, and physiological effects of breathing resistance with and without inspired CO2.
The acceptable level of inspired carbon dioxide (CO2) in diving gear is a controversial topic. Some current standards1,2 permit up to 20 mBar (2 kPa, 2% SEV) as the average inspired CO2 partial pressure, while […]
Just over 45 years ago, in 1970, researchers at the University of Pennsylvania used the best information available at the time to derive a model for development of pulmonary oxygen toxicity.1,2 The measurement they used […]
Central nervous system (CNS) oxygen toxicity literally means the poisoning of the brain by too much oxygen. CNS oxygen toxicity is very scary, particularly in the water, where any of the signs or symptoms poses […]
