+1 on self sufficiency. The way we plan and brief things is that we are all self sufficient but if we bail out in order to cater for excess usage in distress/stress situation, we plan to swap stages at 100 bar. This way the distress diver has more gas than he need and the donating is not with...

That's why I said appears and not just feasible. We have gas density 9,6 g/lt which is twice the recommended max value. But you are right not just END but also gas density. The increased WOB would increase CO2 production and retention and increase the narc level.

Personally I believe that decision making faults are also to be considered human failures. What we will never know is what she planned to do. This because it was a solo dive. We can only make conjectures. But I consider her quite knowledgeable of her equipment (btw I dive the same reb). So she...

Somebody went for a grappling hook as the third dive of the day at 70 meters and got dead for the matter ... quite a high profile case discussed here and elsewhere in SB. Experience just helps normalizing deviance if you do not stick to the rules ...

The way you select a mix for such a dive is ensure you can drop the ppO2 of the loop during a flush, which means a dil ppO2 at target depth of about 1 bar and the target END to select the proper fHe. In a dive like the one reported I would have selected 8/70 It also depends upon my offboard...

I fly planes for work and fun. Flying IFR without autopilot requires way more attention than any rebreather dive I did till now and it still is fun. Back on topic, I saw nothing about the dynamic of the accident and, additionally, if she was solo, not a chance of anybody witnessing the events...

I was a solo diver well before being a reb diver ... When I moved to reb my instructor told me to wait a bit before going solo .... I tend to prefer to be with other reb divers but if unable I dive solo or solo with an OC partner .... My limit is normoxic range and 15-20 min of deco max ...

Not really. My father used to dive O2 rebreather to 20 mt (60+ ft) it was 1950s many things were unknown but the trick was not flushing well to keep the PO2 low. Due to the way the O2 CCR works, it only add gas when the volume goes to below a normal breath (is a demand valve like a second stage)...

Hypoxia: not enough O2 which put you to sleep without warning. Not scrubbing enough CO2 hipercapnia: fast breathing, impending doom feeling, panic, stupor. Kind of different beasts but in shallow water you run for surface for number 2, you sleep and quietly die for number 1.

Same here, I used to run a fidonet bbs ... it was a lot of work but sometime had some ilarious moments :banghead: ... or not!

That is exactly the point. Aircrew cannot even self medicate with over the counter med. We are required to see a flight surgeon for whatever we take because you have no knowledge or competence if that OTC drug is affecting your capabilities to perform as a crew member. In addition flight...

Apparently but non clearly spelled out non dive related medica issue

I saw that couple of days ago .... I love the Google translation of rubber dinghy: 25 ft (8 mt) double 150HP outboard ... The high sea dinghy Classe 300 The usual dinghy Classe GC The fleet of dinghies and other boat! Mezzi navali Apparently Gommone (which is Rubber Inflatable Boat/Rubberd...

Look I do not want to derail the thread but you just are demonstrating the point of getting close o little bit past the limit because it is worth it. This is the same thing the OP did. Except the OP is seeking not to repeat the mistake you think it was worth it. It is not. Either you have the...

But your instructor violated the standards. If he did not follow the standard in one area how can you be sure that your received adequate instruction and he followed them inALL other areas? Just saying ...

Not in boating and not a native speaker, but in aviation. If current regulations allows to maintain a current COI or airworthiness certificate for a vessel or Aircraft built to regulations forty years ago ... well it meets current regulations. Justa a different chapter and verse.

@michael-fisch has it right (no % after the number) but you are correct @rjack321 has it wrong (there is a %) to move from absolute to percent multiply by 100 which is cento in Italian cent in French and centum in Latin.

Since all dives are decompression dives and diving up to the NDL is considered more dangerous than coming up to staged decompression, in term of supersaturation on surfacing (generally speaking and depending upon GF and decompression schedule), I would definitely recommend to ascend from 6 (or...

@Marie13 I do not count dives but I had been diving since 1980, uncertified up to 1994 the OW and AOW until 2003 probably a 1000+ dives all on air, then I did intro to tech e tech deep air, diving on air until 2013 few hundred dives more, still on air ... so yes you can have several hundreds...

Do not read too much into it. People also say knots per hours and energy is usually measured in megawatt hour MWh. So correctly megawatt is already an instantaneous measure of (thermal) power output. This kind of details are irrelevant in such tragedy IMHO.
