Chamber Sup Responsibilities

1. Establish comms
2. Adhere to min manning levels
3. Ensure all team is familiar with ops
4. Ensure DMO is contacted at earliest
5. Patient details are recorded
6. Track BT and dive profiles
7. Dive times are recorded

3

What are the DMO codes?

16U0 - Basic undersea medical officer

16U1 - residency in undersea medical

4

AGE Treatment

Sx improves within first o2 period-tt6
Sx not improved-press to DOR

5

DCS Type 2 Treatment

Sx improve within first o2 period-tt6
Sx not improved-press to DOR

6

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

7

When can you use tt3

Serious symptoms that relieve within 30 min at 165

8

How high can an unpressurized aircraft go with a patient?

1 ata or less than 1000 ft

9

When do you use tt6a?

AGE or DCS when severe symptoms remain unchanged or worsen after first o2 period (20 min)

10

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

11

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

12

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

13

When is tt4 used?

When patient would receive additional benefit from depth of relief. UMO should be consulted.

14

When is a tt7 used?

-Extra extension at 60 fsw
-heroic measure for life threatening or non responsive AGE or DCS

15

What is a tt9 used for?

-residual symptoms from AGE/DCS
-selected cases of CO or Cyanide poisoning
-smoke inhalation

16

Greatest hazard in a chamber

Fire

17

How to compress a patient with an IEB?

Heads up
Slow and gentle

18

When can a patient sleep?

Anytime not on o2
30 feet and shallower on o2

19

How do you tell if a patient is properly hydrated?

Clear, colorless urine

20

85-94 degrees treatments

TT 5, 6, 6a, 1a, 9
6hrs

21

95-104 degrees treatment

TT 5,9
2 hours

22

Can you use expired co2 absorbent?

Nope

23

How does one qualify for a diver pressure candidate test?

Dive physical

23

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

24

What is a level 1 chamber?

On station or within 5 min

CO can authorize it to 7 min

25

What is a level 2 chamber?

One hour
First flag officer can authorize this to be a Non-Navy chamber

26

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

27

Asymptomatic omitted d, no d missed

Observe on surface for an hour

28

Asymptomatic omitted d, less than a min

Return to Stop depth and add a min to first stop

29

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

30

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

31

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)

32

Reoccurrence of symptoms shallower than 60fsw

Return to 60fsw
3 o2 periods

33

Chamber occupants can breathe 100% o2 without locking in additional tenders at what depth?

45fsw or shallower

34

Round window or oval window more likely to rupture?

Round window

35

Differentiate between IEB and inner ear DCS

Place divers head between his legs
If symptoms get worse, IEB
