Initial denial of DCS TYPE II is common. If so, why?
True
Six may not be obvious. Feeling weak or fatigued may be attributed to overexertion.
What is the course of action if treating Type I DCS without a full neuro completed before initial recompression?
Treat as Type II DCS
Do Type I DCS faint skin rashes and itching require recompression treatment?
No
3 categories of Type II DCS
Neurological
Inner ear (staggers)
Cardiopulmonary (chokes)
True/False
Treatment Table 4 can be used with or without O2.
True
•Always use O2 if available
The descent rate for oxygen tables is
20 feet per minute
Which air table is used if pain is relieved at a depth less than 66 feet?
1A
Air table used at a depth greater than 66 feet
2A
Is treatment table 3 an air table or an O2 table?
Air
Which treatment table is used to treat serious symptoms when 02 is not available?
Treatment table 3
As a last resort, when no recompression facility on site, SX are significant, chamber not accessible within reasonable timeframe (12-24hrs), what is an alternative?
In-Water Recompression
Which treatment table is used to treat:
Type I DCS (except curtis marmorata) Asymptomatic committed D Gas gangrene CO poisoning Follow up TX for residual SX Treatment of resolved SX following in water recompression
?
TT5
This TT is used for the following:
AGE Type II DCS SX Type I SX where relief is not complete w/in 10 min. at 60 ft. Cutis marmorata Severe CO poisoning/smoke inhalation Asymptomatic D Symptomatic uncontrolled ascent Recurrence of SX shallower than 60 ft.
What is it?
TT6
Use Treatment table 6A when…
- AGE or D symptoms when severe SX remain unchanged or worsen w/in the first 20 min. At 60 fsw.
- Compress patient to depth of relief or significant improvement NOT to exceed 165 fsw
When it is determined that patient would receive additional benefits at depth of significant relief, not to exceed 165 fsw, shift from what TT to what other TT?
Shift from 6A to 4
