Trauma Lecture 4 Flashcards
1
Q
perfusion
A
delivery of oxygen, removal of carbon dioxide
* properly beating heart
* adequate transport medium (blood and hemoglobin)
* an intact functioning vessel system
2
Q
hypoperfusion
A
widespread inadequate tissue perfusion
3
Q
hypovolemic shock
A
- inadequate amount of fluid or volume
- hemorrhagic and nonhemorrhagic
- bleeding, burns, dehydration
4
Q
distributive shock
A
- widespread dilation of blood vessels
5
Q
types of distributive shock
A
- septic
- neurogenic
- anaphylactic
- psychogenic
6
Q
septic shock
A
- severe infection
- toxins destroy the vessel wall
- capillary permeability
- reduced intravascular fluid
7
Q
neurogenic shock
A
- loss of control of the muscular tone of the blood vessels
- high spinal cord injury
- perfusion to organs decreases
- normal or slow heart rate
- warm skin
- lack of sweating below the injury
8
Q
anaphylactic shock
A
- widespread vascular dilation
- increased vascular permeability
- bronchoconstriction
- stridor
- urticaria, edema, itching
9
Q
psychogenic shock
A
- temporary vasodilation
- syncope
10
Q
cardiogenic shock
A
- heart failure (pump problem)
- no longer maintain sufficient output
11
Q
obstructive shock
A
- cardiac tamponade
- pulmonary embolism
- tension pneumothorax
12
Q
stages of shock
A
- compensated
- decompensated
13
Q
compensated shock
A
body is able to compensate and maintain tissue perfusion
14
Q
decompensated shock
A
body begins to lose its ability to compensate inadequate perfusion begins
15
Q
symptoms of compensated shock
A
- anxious
- cool, pale, moist skin
- normotensive
- normal to slighty elevated pulse
- normal to slightly elevated respirations
