Q

Duration of force application

A

Affects trauma because rapidly applied amounts of energy are less tolerated than an identical amount over a longer period of time

Q

Motorcycle Crashes

A

Helmets transmit forces to the spine
4 types of crashes:
Head on- hit and continue forward until stopped by outside force yielding bilateral femur or tibia fractures
Angular Impact- direct crushing injuries to lower extremity between object and motorcycle
Ejected rider- laying down or sliding results in road rash

A

Every injury possible

40
Q

Level 4 Trauma

A

Able to provide ATLS

41
Q

Children falls more than 10 feet or <10ft with LOC
High risk auto crash
Intrusion intompassenger compartment
Ejection from automobile
High risk injury
Pedestrian/bicyclist thrown 
Burns with other Trauma
EMS provider judgment
42
Q

Special Considerations

A
Age>55 
Systolic <110 in age >65
Using anticoagulants
Pregnancy
Burns with trauma
EMS Judgement
43
Q

Oxygen Dissisociation Curve

A

Affinity of oxygen on hemoglobin and oxygen in plasma
Spo2 and PaCo2
-too much fluid can transfer oxygen from hemoglobin to a larger plasma if there is more fluid cause an increase in paco2 and decrease in spo2
-temperature also effects (sweet tea) and how molecules dissolve
-pH also effects trauma by decreasing chance of transporting oxygen

44
Q

Trauma Triad

A

Ph, hypothermia, infection

45
Q

Pain Management

A

Need to so that there isn’t a massive catecholamines dump

46
Q

Coagulopathy

A

Free bleeders because the body uses all clotting ability when bleeding and runs out so bleeding can not clot

47
Q

Compensated

A

HR increase, lethargic, skin

48
Q

Decompensated

A

Pressure changes signify decompensation

49
Q

Burns

A

Hypovolemia, hypothermia, infection, pain

50
Q

Superficial

A

Burn to epidermis

  • Red color
  • Vulnerable to temp regulation
51
Q

Partial Thickness Burns

A

Burn to dermis
Glands, Nerves, vessels
-Massive fluid shift ! Fluid forms in bubbles

52
Q

Full Thickness Burn

A

Burn to sub

  • no ability to thermos regulate
  • no sensory
  • no fluid containment
53
Q

Airway Burns

A

Stridor, burns to pharynx, nasal hairs

-Edema causes loss of airway

54
Q

Parkland Burn Formula

A

4xBSAxkg half over first 8 then rest over last 16hours

Easy way = BSAxKg/4 = fluid over first 8 hours

55
Q

Dry sterile dressing

A

Dry because the lint does not stick and because bacteria is easier to travel through water than through air. Also, water could cause further hypothermia

56
Q

Wet sterile dressing

A

If moderate burns use wet to smooth. If full Thickness burns then use dry

57
Q

Rule of Nines

A

Adult head 9 Child head 12 Infant Head 18

58
Q

Palm Rule

A

The palm is 1% of TBSA

59
Q

HCl Acid
HFl Acid
-immediate pain and coagulation necrosis

60
Q

Chemical Bases and Alkalis examples

A

-little pain but extensive damage by liquification necrosis. Breakdown of protein, collagen, fats, dehydration of tissues, thrombosis of vessels
61
Q

Oxidizing Agents

A

Hydrogen Peroxide
Sodium Chlorate
-can cause systemic poisoning

62
Q

Phosphrous

A
