Chamber Supervisor Flashcards
This topic will familiarize with supervising recompression chamber operations
Purpose of recompression therapy
Decrease bubble size, restart blood flow, and relieve local pressure
Can recompression treatments be started without an UMO
Yes, consult ASAP
What table can only be prescribed by UMO
TT-9
Who can modify recompression treatment protocols with CO/OIC concurrence
DMO with sub-specialty code 16U0 or 16U1
UMO with sub-specialty code 16U0 or 16U1
What dose Treatment Table 5 treat
- Type I DCS (Except cudas marmoralas)
- Asymptomatic omitted decompression
- Asymptomatic/symptomatic exceeded SurD surface interval
- Follow- Up treatments for residual systems
- HBO therapy
- CO poisoning
What must be completed to use Treatment Table 5
Nuero prior to recompression
How long do you have to achieve complete relief to stay on Treatment Table 5
Complete relief obtained 10 minutes or less or go to TT-6
What depth does O2 breathing start at for Treatment Table 5
60 FSW
How many extensions can you do on a Treatment Table 5
Two O2 periods at 30 foot stop. No air break required between O2 periods or prior to ascent
When does tender breath O2 on Treatment Table 5
Tender breaths 100% O2 from 30 foot stop to the surface
When does tender with previous HBO in the last 18 hours breath O2 on Treatment Table 5?
An additional 20 min of O2 prior to ascent and ascent
When do you use a Treatment Table 6
-Arterial gas embolism (AGE) -Type II DCS systems -Type I symptoms not relieved in :10 - No neuro exam done - Cutis marmorata - Severe CO Poisoning, smoke inhalation - Asymptomatic omitted decompression de - Asymptomatic/symptomatic exceeded SurD surface interval - Treatment of unresolved symptoms following in-water-recompression - Recurrence of systems shallower than 60 fsw
How many extensions can you do on Treatment Table 6
Twice at 60 ft (20-5 cycle) and twice at 30 (60-15 cycle)
When does the tender breath O2 on treatment table 6
The last 30 min at 30 ft and to the surface (If one more extensions all 60 mun of last O2 period)
When does the tender with previous HBO in last 18 hours breath O2 on treatment table 6
add 60 min 100% O2 at 30ft to requirement
When would you use Treatment Table 6A
- Unchanged/worsening symptoms of AGE/DCS within 20 min at 60 SFW - Asymptomatic omitted decompression - Symptomatic omitted decompression
How many extensions can you do on Treatment Table 6A
Sam as TT6 (Twice at 60 ft (20-5 cycle) and twice at 30 (60-15 cycle))
When does the tender breath O2 on treatment table 6A
Tender breaths 100% O2 during the last 60 min at 30 fsw and during ascent to surface for an unmod table or with only 1 extension at 30 or 60 fsw (If more extensions breath O2 at 30 fsw is increased to 90 min)
When does the tender with previous HBO in last 18 hours breath O2 on treatment table 6A
Additional 60 min O2 at 30 fsw
When would you use Treatment Table 4
-AGE/DCS where patient would benefit from additional time at depth of significant relief 165 or shallower -Only for severe DCS Type II or AGE
What do you have to do before commiting to a Treatment Table 4
Consult UMO
What are your procedures for CNS O2 Toxicity (non-convultion)
Remove O2 :15 after all symptoms have subsided resume O2 at point of interruption
What are the procedures for second O2 Tox hit or first symptom is a convulsion
Remove O2 After all systems have subsided, decompress 10 feet at a rate of 1 foot per min Resume O2 If 3 O2 Tox hits contact UMO
Symptomatic Omitted “D” < 50 fsw treatment
Compress to 60 fsw and begin TT-6
Symptomatic Omitted “D” > 50 fsw treatment
Compress to 60 fsw or depth of significant symptoms improve, not to exceed 165 fsw begin TT-6A
Patient only needs to be awake when breathing O2 deeper than?
30 fsw
When can you eat in the camber
Any time
Hydration rate for IV in the chamber
75-100cc/hour
O2 control maintained between
19-25%
CO2 control maintain
< 1.5% surface equivalent
Permissible temperature level not to exceed
> 104 F
Permissible temperature level TT 5 and 9
95-104 F
Permissible temperature level TT 5, 6, 6A, 1A and 9
85-94 F
What is the ventilation rate for air BIBS dump system or closed circuit BIBS
2 acfm resting 4 acfm working
What is the ventilation rate for Oxygen BIBS without a dump system
12.5 acfm resting 25 acfm working
How many treatments can you do consecutively without at least one day break
5 treatments
Post treatment observation period for patients on TT-5
Remain at the facility at least 2 hours 1 hour of chamber for 24 hours
Post treatment observation period for patients on TT-6
Remain at the facility at least 6 hours 1 hour of chamber for 24 hours
Post treatment observation period for tenders
Must stay at chamber facility for 1 hour 1 hour of chamber for 24 hours
Flying after treatment for patient
Minimum 72 hours wait after complete resolution of DCS or AGE
Flying after treatment for tenders
TT-5, 6, 6A, 1A, 2A or 3 at least 24 hours TT-4, 7, or 8 at least 72 hours
Time requirements for tenders to return to diving
TT-5, 6, 6A, 1A, 2A or 3 Min 18 hour SI for No “D” dive Min 24 hour SI for decompression dives TT-4, 7 or 8 Min 48 hour SI
Air required for compression equation
Depth x FV = scf required
33
Air Required for ventilation at depth equation
ata x vent requirement x time = scf required
