|
anaphylactic shock
|
circulatory shock state resulting from a severe allergic reaction producing an overwhelming systemic vasodilation and relative hypovolemia
|
|
|
biochemical mediators
|
messenger substance that may be released by a cell to create an action at that site or be carried by the bloodstream to a distant site before being activated; aka cytokines
|
|
|
cardiogenic shock
|
shock state resulting from impairment or failure of the myocardium
|
|
|
colloids
|
intravenous solutions that contain molecules that are too large to pass through capillary membranes
|
|
|
crystalloids
|
electrolytic solutions that move freely between the intravascular compartment and interstitial spaces
|
|
|
circulatory shock
|
shock state resulting from displacement of blood volume creating a relative hypovolemia and inadequate delivery of oxygen to the cells; aka distributive shock
|
|
|
hypovolemic shock
|
shock state resulting from decreased intravascular volume due to fluid loss
|
|
|
neurogenic shock
|
shock state resulting from loss of sympathetic tone causing relative hypovolemia
|
|
|
septic shock
|
circulatory shock state resulting from overwhelming infection causing relative hypovolemia
|
|
|
shock
|
physiologic state in which there is inadequate blood flow to tissues and cells of the body
|
|
|
SIRS - systemic inflammatory response syndrome
|
overwhelming inflammatory response in the absence of infection causing relative hypovolemia and decreased tissue perfusion
|
|
|
name the shock states that are caused by a loss of vascular tone and what are these collectively referred to as?
|
-septic
-neurogenic -anaphylactic shock CIRCULATORY/.DISTRIBUTIVE/VASOACTIVE SHOCK |
|
|
circulatory shock is aka
|
distributive or vasoactive shock
|
|
|
Physiologic responses that are common to all types of shock
|
1. hypoperfusion of the tissues
2. SNS activation 3. hypermetabolism 4. activation of the inflammatory response |
|
|
What is the final pathway of all shock states?
|
a derangement in the compensatory mechanisms to effectively restore phsyiologic balance
1. inadequate perfusion to the cells that results in a. cellular hypoxia, b. end organ damage, and c. ultimately death |
|
|
What negative effect occurs with anaerobic metablism?
|
-yields less ATP
-accumulation of lactic acid (a toxic end product) which must be removed from the cell and transported to the liver for conversion into glucose and glycogen |
|
|
where is lactic acid transported to after leaving the cell?
|
the liver for conversion of lactic acid into glucose and glycogen
|
