Chamber Misc Flashcards
What are the DMO codes?
16U0 - Basic undersea medical officer
16U1 - residency in undersea medical
Differentiate between IEB and inner ear DCS
Place divers head between his legs
If symptoms get worse, IEB
DCS Type 2 Treatment
Sx improve within first o2 period-tt6
Sx not improved-press to DOR
85-94 degrees treatments
TT 5, 6, 6a, 1a, 9
6hrs
Joint pain aviation DCS after reaching 1 ata
Before reaching 1 ata - 2 hrs of o2 on surface, 24 hr observation after
After reaching 1 ata - tt5
When can you use tt3
Serious symptoms that relieve within 30 min at 165
When can a patient sleep?
Anytime not on o2
30 feet and shallower on o2
Asymptomatic omitted d, 20-30 fsw stop, 1-7 min SI
In water- return to first stop depth, multiply stops by 1.5
In chamber- follow surface d rules
What is tt8 used for?
- treats deep uncontrolled ascent when more than 60 min of decompression is missed
- compress to depth of relief not to exceed 225 fsw
Asymptomatic omitted d, 20-30 fsw stop, over 7 min SI
In water- Return to stop depth, multiply stops by 1.5
In chamber- 2 or less chamber periods, TT5
- 2.5 or more chamber periods, TT6
What is a level 1 chamber?
On station or within 5 min
CO can authorize it to 7 min
When is a tt7 used?
- Extra extension at 60 fsw
- heroic measure for life threatening or non responsive AGE or DCS
When do you use tt6a?
AGE or DCS when severe symptoms remain unchanged or worsen after first o2 period (20 min)
What is a level 2 chamber?
One hour
First flag officer can authorize this to be a Non-Navy chamber
95-104 degrees treatment
TT 5,9
2 hours
AGE Treatment
Sx improves within first o2 period-tt6
Sx not improved-press to DOR
How high can an unpressurized aircraft go with a patient?
1 ata or less than 1000 ft
How do you tell if a patient is properly hydrated?
Clear, colorless urine
Chamber Sup Responsibilities
- Establish comms
- Adhere to min manning levels
- Ensure all team is familiar with ops
- Ensure DMO is contacted at earliest
- Patient details are recorded
- Track BT and dive profiles
- Dive times are recorded
When is tt4 used?
When patient would receive additional benefit from depth of relief. UMO should be consulted.
What is a tt5 use for?
- type 1 DCS except cutis marmorata
- asymptomatic omitted decompression
- resolved symptoms after in water recompression
- follow up treatment for residual symptoms
- CO poisoning
- gas gangrene
What is a tt6 used for?
- AGE
- DCS Type 2
- DCS Type 1 when no complete relief within 10 min at 60 fsw or a neuro isn’t completed on surface
- cutis marmorata
- severe CO poisoning, cyanide poisoning, smoke inhalation
- asymptomatic omitted decompression
- symptomatic uncontrolled ascent
- reoccurrence of symptoms shallower than 60 fsw
Asymptomatic omitted d, less than a min
Return to Stop depth and add a min to first stop
How to compress a patient with an IEB?
Heads up
Slow and gentle
Can you use expired co2 absorbent?
Nope
Reoccurrence of symptoms shallower than 60fsw
Return to 60fsw
3 o2 periods
Round window or oval window more likely to rupture?
Round window
How does one qualify for a diver pressure candidate test?
Dive physical
What is the diver candidate pressure test?
Compress to 60fsw @75fpm (10fpm min)
Stay at 60fsw for 10 min
Candidates will stay at immediate chamber for 15 min
Candidates will stay at facility for an hour
Asymptomatic omitted d, no d missed
Observe on surface for an hour
Greatest hazard in a chamber
Fire
What is a level 3 chamber?
6 hours
CO can authorize this as a Non-Navy chamber
CO can authorize the nearest approved chamber outside of 6 hours in extreme cases
What is a tt9 used for?
- residual symptoms from AGE/DCS
- selected cases of CO or Cyanide poisoning
- smoke inhalation
Chamber occupants can breathe 100% o2 without locking in additional tenders at what depth?
45fsw or shallower
Chamber Manning Levels
Min-3
Ideal-7
Emergency-2
Asymptomatic omitted d, more than 30 fsw stop
In water- return to first stop, follow normal decompression until 30fsw, multiply 30 and 20 fsw stops by 1.5
In chamber- TT6 (stop deeper than 50fsw, compress to 165)
