STAGES OF SHOCK Flashcards
1
Q
what are the stages of shock?
A
non progressive
progressive
irreversible
2
Q
describe nonprogressive shock?
A
reflex compensatory mechanisms activated
perfusion of vital organs maintained
3
Q
what are the neurohumoral mechs that help maintain CO and BP?
A
baroreceptor reflexes
catecholamines
ADH
renin-angiotensin-aldosterone
4
Q
is progressive shock treatable?
A
sure is
5
Q
what are considerations for progressive shock?
A
tissue hypoperfusion
worsening circulatory and metabolic imbalances
-lactic acidosis
6
Q
is irreversible shock treatable?
A
nah
7
Q
what are the considerations of irreversible shock?
A
cellular and tissue injury is so severe that even if hemodynamic stability occurs, survival is impossible
- leakage of lysosomal enzymes
- worsening of myocardial contractile function
- increased nitric oxide synthesis
- ischemia of organs
