As I study to get ready for the CCR class, I discovered something that may be obvious to many but was definitely not to me. “Surface intervals are not always the most efficient way to off-gas nitrogen after a dive”. Depending on the blend, there is an optimal depth at which the off-gassing is...

Saw this on Youtube, thought it would be of interest. If it is in the wrong place, please move it. Diving and Hyperbaric Physiology Some information on IPO and front/back mounted counter lungs. Narcosis etc.

Hello, Im looking for an article, I think it was by SSI,SDI, or NAUI. It pertained to a frequent diver requiring less weight as you rack up your dive numbers (while using the same gear) because your natural respiration is smaller since you regularly dive and your body has become used to...

Hi all, I apologize first of all if there is an existing thread on this topic, I did not see any after a quick search. I also would like to mention I am not a medical professional, so for any other non-experts who follow this thread please consider any of my opinions as nothing more than...

When I took PADI's OWD course. The instructor told us the basic profile for recreational dives with the safety stop, ascent rate and everything else... I was reading NOAA's Diving manual, which recommends to do a stop at half the max depth of the dive for 2.5 minutes, plus the safety stop at 15...

A 2012 study indicates that nitrogen narcosis may persist even after ascent from depth, including at the surface post-dive. What does this mean for divers? Read about the science behind the study... the results... and potential guidelines for divers in my latest article: Does Nitrogen...
