Hey Katja, I think 40m is exactly the MOD at ppo2 1.4 for a EAN28, isn’t it?
pp02 1.4 / fo2 0.28 = 5 bar (=40m).
I wouldn’t really mind to dive with Paul, his dive plan calcs make absolutely sense! ;)
Safe diving!
You BELIEVE it gives you a max ppo2 not higher than 1.4 at 40mt?
Wow! I would not want you as my buddy!
EANx is good in that you feel better after repetitive dives. Surface interval is also shorter. In Coron, Philippines last month the Irako WWII Japanese wreck was dived (40m on deck level 3 where the engine room was) using 28% EANx which I believe gives you a max depth of 40m not exceeding the Po2 partial pressure limit of 1.4. The Urkraine dives who hired out 2 boats used all the Nitrox so I had to use air. The surface interval on the 2nd dive was 1.75 hrs so not ideal. The 3rd ‘shallow’ dive was another penetration dive down to 32m again on air. On all dives we got to 1min NST Deco limit. I had a rash the following day which caused me a little concern – anti fungal cream sorted it as was thankfully due to being in a wetsuit at 32 deg C. Being banged up down to 165ft in a hyperbaric chamber would not have Impressed My Filipino girlfriend at all!! Lol Will insist on Nitrox next time for sure!!
I earned my nitrox card in Bonaire. It was a great place to start using it as you can easily do 4 tanks / day there and greatly reduce the nitrogen loading.
That puts to me to thinking of the instructor for the course. Here name was “F” and she was from Italy and stunningly attractive! She was on the boat for my first nitrox dive and after surfacing she said, “So tell me Jim, do you feel “jounger?” Do you feel “strongger”? There are rumors of this you know?”
I glanced over at my wife and realized I was in VERY dangerous waters!
“yes, it was a great dive!” I replied with a big grin on my face.
So I’m not sure if it was “F’s” statement or something more physiological, but I did in fact feel a bit better…almost refreshed with the enriched O2 content.
Started diving Nitrox 2 years ago. I am 62 years old and it allows me to do 4 dives a day and maintain my alertness and minimal fatique. It also allows for shorter wait times between dives hence 4 is quite doable. Nitrox is a good way to dive for us seniors. I am certified advanced and certified nitrox and it makes you think when gearing up as you have to check the O2 level in the tank as well as set your computer and make sure you know what depth is your max.
