But on 15 August:

"Yep. I have no cards. I am open water only. I self taught myself Nitrox thru books and diving with people who wanted me to use Nitrox so we could dive together. I am very cautious and calm in the water. I am very comfortable as well."


You are dangerous. We will read about you soon, and foot the huge bill for the Coast Guard having to search for your corpse.
I mispoke. Initially I was taught by an instructor friend of mine and dove for a long time without it and recently got the cert so I could get fills in places where people don't know me. What I meant is that I never took any courses beyond OW.

Besides, Nitrox course is something that can be learned thru reading and formulas. PO2, MOD, Contingency Depth, EAD, EAN Tables. Nothing complicated there. Just need to understand the risks and advantages and manage them. Way different then creating a dive plan for a 150-200 foot dive. What mix? How long? What PO2, what MOD, etc. They even offer these courses online and some agencies do not have nitrox certification dives, just class work.
It's pretty straight forward.

Re: High PO2 Hits - Tell us your story

You got the cert in the last week?? Your post was pretty clear not "mispoken".

It is always the guy without a formal cert who says the class is unecessary.

"A buddy of mine by the name of David, dropped down and ended up taking a tank witha wrong mix."

Had your "buddy" taken a course, he would have checked his owned mix and written it on the side of the tank, one way to "manage" the risk...

No amount of education or training is an antidote for stupidity

I explained the post, I was taught by an instructor that no longer teaches proffessionally. He was taught by Jim Mimms(I think).We covered all the course materials at his home and I used his Padi literature(that I still have). I began diving Nitrox and using pony bottles based on his advice and instruction. Nitrox is pretty straight forward. It's not brain surgery as long as you are not pushing the limits.

As far as the O2 hit, I don't have the details, exactly. More imporatnt, to me, were the symptoms he had. Maybe the awarness generated thru reading what I wrote will save someone who encounters the same symptoms.

Not lookin for an inet argument. Getting tired of those. Too busy, not enough time. More important to me is to keep this thread on track regarding O2 hits and maybe we can generate more awarnes regarding this. Maybe you could join us with something positive here.

Re: High PO2 Hits - Tell us your story

A couple of years back I took a minor O2 hit (i think) at around 155 ft on 29%. It felt like my lips and the area around were tingling or asleep. the feeling was kinda like the after affect of being stung in the face by a jellyfish. The feeling went away after rising up around 60ft or so and leveling off. The current was ripping and I had kicked hard all the way down to get to the jug line. I decided after that to get further training before i ended up on the RIP thread. Several more experienced divers said it was likely an O2 hit and I was lucky to be telling about it? If they were wrong I would like to hear other explanations.

Lee said he took an informal Nitrox Class. The only problem I have is the liability side of the Instructor. Are you referring to "the open water dives" that need to be completed along with the class to get a Nitrox card?

I have no idea why any student would have to complete two dives on Nitrox to complete the class! Can an Instructor from one of those Training Agencies give me me any type of answer as to why the two dives are necessary?

Possibly oxygen, but I have been pretty narced, especially while working hard and ended up with numb lips and tongue (but it was somewhat deeper). Either way, if you don't feel right, you did the right thing and got on the inflator.

Re: High PO2 Hits - Tell us your story

It was the same feeling (see my last post) that had me worried I was close to ox tox on deeper dives, but I found out from talking to tech divers over here that you can also get it with high nitrogen/CO2.

Re: High PO2 Hits - Tell us your story

Another great thread Love it or hate it, information is being shared and discussed.

Since we are looking at medical related I have a question. Last dive of the day, usually after 3 or 4 dives, towards end of dives alot of times I get cramps in quads. I have been reading up on it, and I believe it is related to dehydration. Is this a solid assumption?? Usually during safety stops at end of dive.

Probably dehydration or just lack of fitness. I would drink some Gatorade next dive trip & see if that doesn't help. If not, do some time in the gym.
