SONG DEDICATION TO MY MOTHER
“Beloved” Words and music by VNV Nation

It’s colder than before
The seasons took all they had come for
Now winter dances here
It seems so fitting doesn’t you think?
To dress the ground in white
And grey

It’s so quiet I can hear
My thoughts touching every second
That I spent waiting for you
Circumstances afford me
No second chance to tell you
How much I've missed you

My beloved do you know
When the warm wind comes again
Another year will start to pass
And please don't ask me why I'm here
Something deeper brought me
Than a need to remember

We were once young and blessed with wings
No heights could keeps us from their reach
No sacred place we did not soar
Still greater things burned within us
I don't regret the choices that I've made
I know you feel the same

My beloved do you know
How many times I stared at clouds
Thinking that I saw you there
These are feelings that do not pass so easily
I can't forget what we claimed was ours

Moments lost though time remains
I am so proud of what we were
No pain remains, no feeling
Eternity waits
Grant me wings that I might fly
My restless soul is longing
No pain remains, no feeling
Eternity waits

BLUE HOUSE MULTIMEDIA: W44 Street New York, NY,

Remembering my Mom
Current mood: melancholy
Category: Life

May 6, 2008, marks the 2nd anniversary of my Mother (Mary E Kurland) death. When she died at 3 AM, I was in North Carolina driving up I95. I wanted to say good-bye, one last time but I did not make it.

Yesterday, my kids, and me visited her gravesite. My daughter left an origami crane with a message to her "Grandma Mary". We all cried and hugged.

My son asked me "What happened when we die?" I said, "I don't know, I don't know."

Alone at the marker, I said my goodbyes to my Mom, it is time to move on, to live in the moment. Her grandchildren are growing up so fast and its time for to let go of the pain. Only now, can I remember her and not cry but smile and be glad for all that she gave me.

Good by Mom, I love you so much. I will always remember you.

Joseph

SPECIAL EVENING EVENTS
* Friday – Wreck Penetration presented by Richie Kohler and John Chatterton
    * Saturday – Cave Penetration presented by Jarrod Jablonski
Workshops Overview

PHYSIOLOGY WORKSHOP PLAN
Respiration
Normal respiration and gas exchange at sea level with emphasis on oxygen uptake, CO2 elimination, and ventilatory control. Dependency of CO2 elimination on ventilation. CO2 retention and individual susceptibility. Effects of tidal volume and dead space on alveolar ventilation. Hypo- and hyperventilation. Ventilatory capacity, physical fitness, and respiratory muscle fatigue. Effects of immersion and gas density. Airway collapse and effort independent expiratory flow. Equipment dead space, static lung load, breathing resistance, and work of breathing. Effect of HPNS on respiration. Case reports.

CNS Oxygen Toxicity
Relevant mechanisms of CNS toxicity: free radicals, ventilation, CO2 retention, cerebral blood flow. Risk factors and individual susceptibility. Donald’s WWII studies. Estimating CNS toxicity risk in relation to O2 exposure, review of O2 exposure guidelines, and the O2 clock. O2-CO2 interactions and “Shallow Water Black-Out.�? Mixed-gas O2 exposure limits. Recovery from CNS toxicity risk during underwater air breaks. Case reports.

Narcosis and HPNS
Signs and symptoms of nitrogen narcosis; individual susceptibility, accommodation and adaptation to narcosis; effects on narcosis of rate of compression, oxygen and carbon dioxide; onset depths of narcosis; narcotic potencies of N2, He, Ne, Ar, Xe, O2and CO2; oxygen narcosis; recommended depth limits for air diving; mechanism of narcosis; pressure reversal; utility of EAD/END (equivalent air depth/equivalent nitrogen depth). Signs and symptoms of HPNS; individual susceptibility; depth of occurrence; effect on HPNS of compression rate and time at depth; effect of trimix; effect of hydreliox; mechanisms of HPNS; options for reducing HPNS effects given obligatory fast descent rates.

Thermal Mechanisms of heat transfer (radiation, conduction, evaporation, and convection) with application to divers. Physiological temperature control and consequences of heat transfer (work; shivering; regional vasoconstriction; stages of hyperthermia and hypothermia; freezing and non-freezing injury). Respiratory heat transfer (inert gas and density effects). Rewarming and thermal afterdrop (“warm and dead�?). Drysuit insulation properties of Ar, He, CO2, air and O2 (is this safe?). Insulation properties of wet undergarments. Tools for thermal modeling. Hotwater suits for shallow in-water decompression stops vs. insulation for dry decompression. (Thermal effects on decompression will be covered in the Decompression Workshop.) Current and new active and passive technologies (power sources, hydrogen thermal batteries, hydrogen catalytic heating, regional rewarming, aerogel garments).

1. DECOMPRESSION WORKSHOP PLAN
2. DCI Pathophysiology
3. DCI signs, symptoms and pathophysiology. Paradoxical thromboembolism and cryptogenic stroke. AGE: pulmonary barotrauma, ASD, PFO, and transpulmonary passage, Type III DCS. PFO detection and diver evaluation. Transpulmonary passage and bubble size. Evidence associating DCS with PFO. Skin bends and PFO. Exercise and pulmonary shunt. PFO correction. Case reports.
4. DCS Risk Factors
5. VGE as a measure of decompression stress. Environment: temperature, immersion, exercise. Influence of dive phase (pre-, bottom, deco, post-). Individual: obesity, gender, age, aerobic fitness, individual susceptibility. Adaptation, hydration, alcohol, previous DCS, injury.
6. Deep Stops
7. History and theory of deep stops. Empirical methods and rules. Supporting evidence and experimental data. Validation of methodology.
8. In-Water Recompression
9. Review of IWR experience. Appropriate signs and symptoms for IWR. Equipment and procedures to minimize IWR risk in event of decompression emergency with no access to recompression chamber. Training requirements. Environmental conditions. Depth measurement and control. Diver monitoring and tending. Surface support. Emergency procedures. Outcome reporting.
10. DCS Risk Assessment
11. DCS probability and severity in air and nitrox diving. DCS severity and acceptable DCS risk. Technical diving database, risk analysis and dive condition effects. Examples of tech dive profiles and outcome data. Diver Health Status Form (DHSF). Uploading dive profile and DHSF data to DAN Website. Are technical divers self-selected?
12. REBREATHER WORKSHOP PLAN
13. US Navy and UK/EU Perspectives on Rebreather Test Methods and Standards
14. Rebreather divers must overcome the work of breathing due to breathing resistance, static lung load, and elastance. Inspired CO2 amplifies these effects by increasing ventilation. CO2 sensors and scrubber gauges would decrease this risk. CO2 canister duration is tested as a function of temperature, workload, and depth. O2 control accuracy is assessed.
15. Testing should be performed on breathing machines and by divers. What US and EU labs are qualified to test rebreathers? What is the role of failure mode effect and criticality analysis (FMECA) in rebreather design? New U.S. Navy performance standards are based on diver tolerance. U.S. Navy and EU rebreather test standards should not differ, but do.
