DWS LOOK UPS Flashcards
What are the levels of HAZMAT?
FATCOC F - flammable A - aerosol containers T - toxic materials C - corrosive materials O - oxidizing materials C - compressed gases
What are the differences between CNS O2 tox and Pulmonary O2 tox?
The main difference is the amount of time exposed to O2. CNS can be relatively quick at higher pp
CNS -
(high pressure oxygen tox)
typically occurs when ppO2 exceeds 1.3 ata wet and 2.4 ata dry
Pulmonary -
(low pressure oxygen tox)
can occur anytime the ppO2 is 0.5 aTA or greater
12 hours at 1ata will cause mild symptoms and 4 hours at 2 ata will cause mild symptoms
What are the 6 parts of a neuro?
Mental Status Coordination Motor (Strength) Cranial Nerves Sensory Deep Tendon Reflexes
Explain the strength scale in a neuro?
0 - Paralysis
1 - Profound Weakness (Flicker/Trace)
2 - Severe Weakness (Contration, no gravity)
3 - Moderate Weakness (yes gravity)
4 - Mild Weakness (slight resist examiner)
5 - Normal
What is considered HP and LP?
HP - greater than or equal to 1000lb/in2
LP - less than or equal to 150lb/in2
What alternative ways can air be procured when the commercial air source does not have proper documentation that can be verified IAW the Dive Manual CH.4 Table 4-1?
Air generated by a non-US Navy owned compressor may be used if the supplier can provide documentation that meets the standards of table 4-1 and is approved by the CO
Air generated by a non-US Navy owned compressor that does not provide documentation that meets the standards of table 4-1 may be used for an INDIVIDUAL MISSION not to exceed 30 days if the CO approves it.
The air source will be evaluated against the requirements of the Non-Navy Compressor Check Sheet.
What is the minimum emergency equipment for the side?
- Comms capable of reaching help
- Fully stocked first aid kit
- Portable O2 with enough capacity to reach chamber or planned evacuation location
- AED
- A BVM that can connect to 100% O2
- Stretcher (means of immobilizing an injured diver)
- Extraction Line ( means of extraction for unconscious or stricken diver)
Explain the direct & indirect bubble effect?
Dive Manual Pg. 3-51
Direct - The effect a bubble has when it forms in a tissue or in the bloodstream.
- Can occur within minutes to hours
- Primary Treatment is recompression
Indirect - Bubbles have an indirect effect within the body by acting as foreign bodies (such as a splinter in your hands)
- Takes place over a longer period of time than direct
- The bodies immune system starts to attack the bubble leading to health complications (clotting, allergic reaction, shock, Respiratory Distress, etc..)
- Recompression isn’t enough to treat this
What are symptoms for Type 2 & AGE?
U - unconsciousness W - weakness P - paralysis N - numbness E - Ears, ringing, roar B - blurred vision D - dizziness F - fatigue P - pins and needles
What are the symptoms for Type 1 DCS?
P - pain
M - marbling of the skin
S - swelling of the lymph nodes
What are the symptoms for CNS O2 Toxicity?
V - vision E - ears, ringing, roaring N - nausea T - twitching, tingling I - irritability D - dizziness C - convulsions
What are the symptoms of subcutaneous emphysema?
Fullness in throat
Change in voice
Difficulty swallowing
Rice Krispies (crepitus)
What are the symptoms of mediastinal emphysema?
Substernal chest pain
Tightness or dull ache in chest
Pain radiating to shoulder or upper back
Coughing
What are the symptoms of a pneumothorax?
Sudden sharp chest pain Shortness of breath Labored breathing Weak pulse Increased heart rate Anxiety
What is mediastinal emphysema?
When gas expansion forces gas into the loose mediastinal tissues in the middle of the chest
