(12) Shock Flashcards
obstructive shock
hypoperfusion caused by the heart being physically prevented from pumping fully
BLS treatment for shock
- ABC
- Keep warm
- Rapid transport
decompensated shock
state of hypoperfusion in which the bodies normal defense mechanisms against hypoperfusion have begun to fail
nuerogenic shock
type of distributive shock in which damage to the brain or spinal cord have resulted in failure of communication with the sphincter muscles resutling in wide spread dilation
which of the following is the most reliable indicator of early shock:
- polydipsia
- AMS
- hyptension
- tachycardia
- AMS, the brain is very sensitive to changes in T, pH, and O2, so when hypoperfusion occurs, the brain responds first
s/s of decompensated shock
- cyanosis
- absent peripheral p
- falling bp
compensated shock
state of hypoperfusion in which the body has activiated its defense mechanisms to maintain body perfusion to the brain, heart, and lungs
edema
local over accumulation of fluid in the interstitial space
hypovolemic shock
type of shock associated with an inadequate supply of blood or fluid
at what percentage of blood loss, does a patient experience sever shock?
35%
septic shock
a type of distributive shock, infectious agents have entered the blood stream, causing malfunction of sphincter muscles and increased permeability of the capillary
irreversible shock
state of shock from which a patient can not be revived
s/s of compensated shock
- ams
- rapid p and resp
- pale skin
- diaphoresis
- nausea
MODS
multi organ disfunction syndrome, is what causes death with shock patients
cardiogenic shock
type of shock caused when the heart does not have adequate strength to pump effectively. can be gradual as with CHF or chronic as with an acute MI
