Jay,
When you professional Sat divers are working, are there personnel topside trained in dive physiology and medicine to make a quick call as to what treatment for x incident should be employed? Individual history can also be a big factor here.
This is applicable to psubbers in the event of an incident /accident at depth in that where you live and operate, can make quite a difference. For example, here in Florida, diving accidents are expected, and appropriate facilities / personnel available. Quick transport via C.G. helo, is a VHF call away. We are very very fortunate in that regard.

PSUBS.ORG PO Box 53 Weare, NH 03281 603-529-1100 ************************************************************************ ************************************************************************ ************************************************************************In diving and other hyperbaric scenarios there are two types of oxygen poisoning that can occur. The first, more common, is a result of high O2 partial pressure at depth and results in aberrations of the body?s chemistry causing neurological difficulties (convulsions being the worse and can result in death rapidly). The other results from breathing O2 at high concentrations at low pressure for a long time. The high O2 irritates the lungs resulting in fluid build-up (potential for pneumonia). This is why patients on O2 are taken off for short periods after 48 or 72 hr. exposures (if I remember the timeframes correctly). This is the limiting factor for underwater habitats in shallow water breathing straight air (Jules? Underwater Habitat in ~33 fsw is limited to 72 hour stays). An early symptom of this is a tightness in the chest.
Dr. Bill Hamilton developed an inexact formula for keeping track of O2 exposures at pressure as a guide. It is inexact as each person reacts differently to high O2 exposures day to day.

Here is a link regarding 02 toxicity as applicable here. http://scuba-doc.com/o2tox.htm
I see the effects of 02 toxicity frequently in the ICU, (chronic obstructive pulmonary patients)...not a pretty picture. Different route of getting there but, same symptomatology.

Date: Sun, 28 Jan 2007 10:40:27 ESTFor what it's worth,
I had a close friend that got badly bent with a CNS hit. He was treated in a Hyperbaric chamber to 99 ft (pure O2) for 25 times. He should have been treated by Table 6 in a decent re compression chamber.He still has problems after 10 years.
I don't recommend a Hyperbaric chamber.
