Transcript of Decompression Sickness
What Is Decompression Sickness?
Mild forms of decompression sickness can resolve themselves
Follow-up treatments, along with physical therapy
-My Personal DCS/DCI ("Bends") Story By: Alan Levy time: May 24th, 2002
- Did two dives on this past Friday (May 24th, 2002) as part of PADI MSDT training
- Ended up with decompression sickness
By: Tammy Ngo & Tina Nguyen
Diving history will give some indication as to whether it could be decompression sickness.
Can diagnose DCS through examining the balance, coordination, sense of touch, reflexes and muscular strength.
It's a condition that results when sudden decompression causes nitrogen bubbles to form in the tissues of the body.
Affects divers and other people who are in a situation that involves pressure rapidly decreasing around the body.
Occurs most frequently during deep sea diving
Nitrogen is taken into the body's tissues
Main risk factor: diver ascends too fast
Other risks: deep or long dives, cold water, hard exercise at depth
Bubbles forming in or near joints
MECHANISM OF INJURY
How do you Diagnose the Condition?
Pain in joints and/or muscles of the arms, legs or torso
Ringing in the ears
Shortness of breath
Numbness, tingling, paralysis
Confusion, personality changes
Collapse or unconsciousness
Coughing up bloody, frothy sputum
Always ascend slowly
Use dive tables (shows how long you can remain at a given depth)
Do decompression stops (stopping at certain depths in the water for a calculated length of time)
Don't drink alcohol before/after diving
Don't fly within 24 hours after diving
Mechanism of injury:
- 80 Feet maximum depth for a total bottom time of 40 minutes (average depth was 37 feet and the water temperature was 54 degrees)
- Maximum depth of 45 feet for a total bottom time of 56 minutes (average depth was 23 feet and the average temperature was 46 degrees)
* I had ample dive time left *
-felt fine, no joint or muscle pain, but he felt kind of "foggy" on the brain
- next morning, left leg and arm felt "strange",
-same symptoms were present after a couple of hours
- loss strength in left leg compared to the right
- brought down to 60 feet and then to 30 feet.
-each level breathed 100% oxygen for 20 min
-joint pain was gone and “foggy head”
-only one treatment was needed
- at least one week off
-symptoms were mild and treated in time
His Final Thoughts/ Prevention
1. You can do everything right - by the book and still get a hit of DCS.
2. Trust that inner voice; it knows when something is wrong.
3. If something is wrong, get it looked at and if there is something wrong get it treated ASAP - with DCS time is our enemy.
4. DCS is a scary thing but the camber ride isn't - I lost part of a day saw two good movies and got to sit on my back for four hours.
5. If you think you might have DCS, get it looked at BEFORE you step foot on any airplane, if you fly it will only make treatment harder and the time we don't dive longer
