The Dewey Monitor: Pulse Oximetry can Warn of Hypoxia in an Immersed Rebreather Diver in Multiple Scenarios - Annals of Biomedical Engineering Divers who wish to prolong their time underwater while carrying less equipment often use devices called rebreathers, which recycle the gas expired after each breath instead of discarding it as bubbles. However, rebreathers’ need to replace oxygen used by breathing creates a failure mechanism that ...

Returning To Diving After A Concussion When and how should you return to diving following a traumatic brain injury? GUE’s NextGen Scholar, Kiwi water-woman Annika Andressen spent eight months figuring out the answers to those questions with the help of Dr. Simon Mitchell, after suffering a concussion while surfing. Here is her tale of ...

Increasing The Probability Of Surviving Loss Of Consciousness Underwater When Using A Rebreather With divers soon returning to the loop, the Rebreather Training Council (RTC) is currently considering a number of initiatives to improve rebreather diving safety. One of those is to recommend the use of mouthpiece retaining straps aka “gag straps” to prevent drowning in the event of loss of con...

Everything You wanted To Know About PFOs and Decompression Illness, But Were Too Busy Decompressing to Ask Though your chances of getting bent are relatively low, your risk increases five to 13-fold in the presence of a patent foramen ovale (PFO), which may enlarge and become problematic with age. Skin bends anyone? Here cardiologist and rebreather instructor Doug Ebersole explains the latest research, w...
