IT Misc Flashcards
What are dermatomes?
Reflect the course of the sensory nerves
- trunk run horizontally
- Extremities run vertically
Grading scale for strength
5-normal, equal bilateral strength
4-mild weakness, able to resist slight force
3-moderate weakness, able to overcome gravity but not the examiner
2-severe weakness, able to contract muscle but not overcome gravity
1-profound weakness, flicker or trace of muscle contraction
0- paralysis
What are the 4 DTR results?
Normal, nonexistent, hypoactive, hyperactive
-equal and bilateral
Anaphylactic shock
Caused by severe allergic reaction
Cardiogenic shock
Caused by heart attack or poor heart function
Hemorrhagic (hypobolemic) Shock
Caused by large amount of bleeding
Neurogenic Shock
Caused by uncontrolled dilation of blood vessels due to nerve paralysis caused by spinal chord injury
Psychogenic Shock
Caused by fright or fear
Stages of shock
Compensated-body corrects for loss/lack of blood to tissues
Decompensated-body no longer can compensate
Irreversible-body cannot maintain tissue perfusion, may lead to organ failure
Symptoms of shock
Increased heart rate
Increased respirations (progresses to short/shallow/rapid)
Pale/cool skin
Blood pressure drops (life threatening/late sign)
Thirst
Dilated pupils
Cyanosis
Nausea/vomiting
Responsibilities of an inside tender
- Release dog latches
- Comms
- Provide first aid
- Administer tx gas @ tx depth
- Provide normal assistance
- Hearing protection
- Ensure patient lies down (blood flow)
Nondiver Inside Tenders
Completed PQS
Current dive physical
Conform to navy physical standards
Passed pressure test
What size needle for needle d
Large bore
14 gauge or larger
Size of needle for iv
16-18 gauge
Only authorized antiseptic in chamber
Betadine
How do you insert iv needle
30 degree angle, bevel up
How big is the syringe in a urinary catheter?
10cc
How much urine do you remove with a catheter?
700-1000ml to avoid bladder shock/spasm
What is a direct effect of a bubble?
Obstruction of blood flow
What is an indirect effect of a bubble?
A pathological response to the bubble
What is edema?
Fluid build up in the body
Pulmonary o2 tox occurs when long exposures to
0.5 or greater o2 concentrations
CNS o2 tox occurs when ppo2 exceeds
- 3 wet
2. 4 dry
Type 1 pain
shoulder, elbow, wrist, hand, knee, and ankle
Type 2 pain
abdominal and thoracic areas, including the hips
6 nevers of recompression treatment
- Alter treatment tables without a dmo
- Wait for a bag resuscitator
- Interrupt chest compressions for more than 10 sec
- Use 100% o2 past 60fsw
- Fail to treat doubtful cases
- Allow patients to be in a cramped position
When does inner ear dcs mostly occur?
In heo2 diving when switching from heo2 to air
How long are o2 periods in treatment tables?
20/5 @ 60fsw
60/15 @ 30fsw
How long of a surface interval for tenders between consecutive treatments (1a,2a,3,5,6,6a)?
18hrs
How long of a surface interval for tenders between consecutive treatments (4,7,8)?
48hrs
Diving after a treatment wait time (1a,2a,3,5,6,6a)
18hrs- no decompression
24hrs- decompression
Diving after a treatment wait time (4,7,8)
48 hrs
TT5 Inside Tender Considerations
- Ascent from 30fsw
- previous hyperbarics in the last 18; :20 @ 30fsw
TT6 Inside Tender Considerations
Ascent from 30fsw
up to One ext. - :30
Two ext. or more - :60
Prev hyperbarics - :60
TT6a Inside Tender Considerations
Ascent from 30fsw
Up to One ext - :60
Two or more ext - :90
Previous hyperbarics - :60
Inside Tenders flying after diving
1a,2a,3,5,6,6a- 24hrs
4,7,8- 72hrs
What equipment can you find in a primary med kit?
Diagnostic and therapeutic
What kind of equipment is in the secondary med kit?
Medicine and other equipment that can be locked in
Factors that effect CNS O2 tox susceptibility
- water immersion
- co2 retention
- individual susceptibility
- exercise
- depth
- intermittent exposure
How to treat Shock
- Ensure adequate breathing
- Control bleeding- pressure points or tourniquet
- 100% o2 for better circulation
- Elevate extremities
- Avoid rough handling
- Prevent loss of body heat
- Keep patient lying down
- Give nothing by the mouth
How much should a patient drink in a normal treatment table?
1-2 liters
What’s in the primary med kit?
Diagnostic and therapeutic equipment
What’s in the secondary med kit?
Medicine and misc equipment
