Where the fractured bone remain within the body

34
Q

35
Q

If a person has suffered multiple injuries; two AIS1 head/neck injuries, one AIS2 chest injury and one AIS4 pelvis injury. What is the resulting ISS value for this person’s injuries?

A

A^2+B^2+C^2 : 1+4+16=21

36
Q

What is most true for the Thoracic Compression Criterion?

A

Injury criterion for the thorax in the case of frontal impact that takes into account the maximum compression of the thorax

37
Q

Abbreviated Injury Scale (AIS) levels are

A 
AIS0: No injury
AIS1: Minor
AIS2: Moderate
AIS3: Serious
AIS4: Severe
AIS5: Critical
AIS6: Maximal
38
Q

Deltoid is:

A

A shoulder muscle

39
Q

Compound bone fractures are thoe where:

A

The bone protrudes the skin

40
Q

Abbreviated Injury Scale (AIS) chapters corresponding to nine body regions:

A
  1. Head
  2. Face
  3. Neck
  4. Thorax
  5. Abdomen
  6. Spine
  7. Upper Extremity
  8. Lower Extremity
  9. External and other.
41
Q

The ISS is based upon the Abbreviated Injury Scale (AIS). To calculate an ISS for an injured person, the body is divided into six ISS body regions. These body regions are:

A
  1. Head or neck – including cervical spine
  2. Face – including the facial skeleton, nose, mouth, eyes and ears
  3. Chest – thoracic spine and diaphragm
  4. Abdomen or pelvic contents – abdominal organs and lumbar spine
  5. Extremities or pelvic girdle – pelvic skeleton
  6. External
42
Q

What is the rules of ISS?

A
  • Take the highest AIS in each of the three most severely injured ISS body regions
  • Square each AIS code and add the three squared numbers
  • The ISS scores range from 1 to 75
  • If any of the three scores is a 6 => the score is automatically set at 75
43
Q

What is the most common head injury for in vehicle occupants in traffic accidents?

A

Concussion

44
Q

Which of the following ATDs are most commonly used in federal frontal crash testing?

A

Hybrid III

45
Q

Which of the following lists make up the most complete collection of cranial bones?

A

Temporal bones, parietal bones, occipital bone, frontal bone and sphenoid bones.

46
Q

Which of the following ATDs are most commonly used in side impact crash testing?

A

The SID (Side Impact Dummy) family of test dummies is designed to measure rib, spine, and internal organ effects in side collisions.

47
Q

Which of the following ATDs are most commonly used in rear impact crash testing?

A

BioRID is a dummy designed to assess the effects of a rear impact. Its primary purpose is to research whiplash, and to aid designers in developing effective head and neck restraints.

48
Q

Which of the following ATDs are most commonly used in children crash testing?

A

CRABI is a child dummy used to evaluate the effectiveness of child restraint devices, including seat belts and air bags. There are three models of the CRABI, representing 18-month, 12-month, and 6-month-old children.

49
Q

Which of the following obese ATDs are most commonly used in crash testing?

A

FGOA is a first generation obese anthropometric test device which can be used to study the automotive safety challenges for obese occupants, who are believed to have higher risk of mortality in automobile collisions comparing to non-obese occupants.
