I would agree with you it sounds like CO2. Do the headaches occur using both masks? Are the oral nasal valves in good condition and properly installed? Have you noticed any of the divers skip breathing / slow breathing / conserving air rates during training? Your compressor is...

A diving injury can cause cell death by denying an area of tissues circulation (oxygen) If you ever suspect there is any possibility that a symptom is related to a diving injury rapid treatment is the best policy, delays in treatment severely decrease the effectiveness of hyperbaric therapy...

Persistent vertigo is vertigo (spinning sensation) that lasts for longer than a few minutes. Some potential causes: Inner ear DCS AGE - (arterial gas embolism effecting the either vision or inner ear function) Inner ear damage (round or oval window rupture or tear causing a leak of...

1) I have an older military 5.1 (Mako) and have purchased several smaller units for previous operations. 2) New, the Junior is right around $4000 but if your going to make the investment (especially if you intend to do more than a couple cylinders at a time or blending) I would step up to the...

It is going to depend, you will need to get a complete dive physical and depending on your age either annual or bi-annual physicals while your working. Among other things this includes a chect x-ray to aid the DMO in making a determination, if there is no visible scar tissue and you are not...

Damn!!!! I am so jealous!!! I would prefer a standard but the defender is my dream vehicle... Could you post a picture if you get it? Are you getting a decent deal on it? Does it still have the hard top...

Did you experience any difficulty clearing during your dives? One possibility is that you damaged your inner ear, persistent vertigo is not a normal condition after any dive and can indicate a very serious injury. I would suggest you call DAN, I would also schedule an appointment with an...

The bubbles are re-absorbed by the body within the first 24 hours normally. Recompression therapy works best when conducted as soon as possible after an injury, if the nitrogen is still present and causing problems it will be most effective since it will speed elimination of the bubbles...

Equilization time: When you travel to destination at altitude or a lower ambient pressure your body is off gassing, adjusting from the amount of nitrogen present at sea level .79 ATA to the amount present at your destination. For an altitude of 1200 m upon arrival you would a repetative group...

It sound like it could be fluid in your middle ear, have you ever had any pressure or pain even though you were clearing? It is possible that you have a physiological problem that makes transfer of air through the eustacian tube more difficult. Have you ever spoken with an ENT about the...

As I have already stated I am sorry to see the death of a young man especially one who choose to serve his community, but I am glad to see the employer being held accountable for an unsafe operation and would expect the same if I was running an unsafe operation.

Was it a monoplace chamber (single compartment for the patient, normally made from acrylic) or were you in the chamber with a tender breathing from either a hood or bibbs mask? Monoplace chambers usually are set up to vent the O2 and supply only air for the required air brakes, when breathing...

They were talking about releasing a version on the balanced EXO regulator platform, check this: http://www.kmdsi.com/products/exo.html If it is not what your looking for let me know, the research office www.divelab.com is right in town here.

Could it have been a TT-9 / Kendall table? (treatment depth is 45 FSW) the O2 breathing periods are longer.

The only symptoms I have seen post treatment were residual in nature from the orignial acident, often if people delay getting to the chamber the bubbles do thier damage (even if the N2 is eliminated the symptoms remain to some extent due to tissue damage) Other things patients will notice...

All engineer diving, I was at Ft Eustis with the 544th, 511th, 86th, and 569th at various times and down in Panama City at NDSTC. I worked on equipment / exchange with some of the guys from GA RTBG while I was in PC. We may know some of the same guys. I got out in 2001 and settled down...

"work smarter not harder" Good idea to use the handtruck

I have always used a pair of socks to slide my feet through. You could also try getting a dive skin as mentioned above. You may want to try a looser suit, even if rented and decide if the hassel of fighting a tight suit is worth the extra warmth or not.
