*SHOCK* Flashcards
Shock:
inadequate perfusion
Septic shock can do what?
releases masssive histamine release, lowering BP.
Compensated Shock?
increased Beta1, Alpha 1
increased depth and rate or respiration
tachycardia, tachypnea, pale, cool, moist, normotension.
relative hypovolemia? the 4 shocks
container problem ( vasodilation)
absolute hypovolemia
Volume ( Hemmorage, metabolic)
cardiogenic and obstructive shock?
pump problem.
stage 1 of hypovolemic shock?
Mild
<15% blood loss
minimal vital changes and blood loss
stage 2 of hypovolemic shock
moderate
20-25% blood loss
pulse and resp increased
thirst and pallor present
stage 3 hypovolmeic shock
seevere
30-35% blood loss
mechanisms failing
** all signs of shock possible**
stage 4 hypovolemic shock
Catastropic
>40% blood loss
no palpable pulses
Chemoreceptors?
changes in chemical levels
ex: c02,O2, glucose and acid & base balance
Baroreceptors?
sense decrease in BP
where are baroreceptors located?
carotid and aortic arch.
hypovolemic shock signs and symptoms? compensated.
tachycardia
normotension
cardiogenic sock?
irregular pulses
