Bill, I just want to repeat the last two pargraphs of your post as an
instant replay for these know it alls. I also want to reitterate that
time is eveything, and instant action is everything.

If the training agencies and other terrified pussies did not teach fear
of deco and did not teach assinine responses ( like what the weenies on
here are recommending) we would likely have seen most of the tech diving
deaths reported as saves , not deaths.

This is a function of the attitude that these people display on here.
That attitude is not tolerated in the Woodvile Karst Plain Project, and
we fight over who gets to ax anyone who displays it.

Your post below is right on the money.

In the case of a hypoxic diving accident there is an immediate and
pressing
need to get oxygen into the alveoli to restore hemoglobin levels. Below
100
mm Hg there is a steep slope in the Hb-O2 saturation curve and the blood
supply almost immediately becomes totally oxygen deficient.  A demand
regulator applied to an unconscious or drowned diver is the most
immediate
way to ventilate the lungs, providing the breathing passage is
reasonable
clear, to get oxygen to the blood.  Remember that anything you can get
into
the lungs at this point is better than the nothing that is already
there.
Pure oxygen is vastly preferable to expired ventilatory gas, inasmuch as
the
oxygen content of inspired gas has been displaced by co2 and moisture.
Obviously, the airways must be open and the direct leakage of
respiratory
gas to the external environment must be controlled.

In an operating theater or an ambulance masks and bags may be
appropriate;
however  on the surface of the ocean or the sinkhole the most immediate
action must be taken in the timeliest of fashions to spare the victim
his
life or his future functionality.

Best regards,

Bill Mee
