Chapter 42: Shock, Sepsis, and Multi Organ Dysfunction Syndrome: Stages of Shock Flashcards
failure of one organ system affects others, recovery unlikely
refractory
Ischemic mucosal barrier of GI system causes ulcers, GI bleeding, risk of bacteria migration, decreased nutrient absorption ability
progressive
Decreased blood flow to kidneys activates renin-angiotensin system
compensatory
Anasarca: fluid leakage affects solid organs and peripheral tissues; decreased blood flow to pulmonary capillaries
progressive
myocardial dysfunction causes dysrhythmias, myocardial ischemia, and possible MI, leading to complete deterioration of cardiovascular system
progressive
Fluid moves from pulmonary vasculature to interstitium, causing pulmonary edema, bronchoconstriction, and decreased functional residual capacity
progressive
Stage that begins when compensatory mechanisms fail
progressive
If corrected in this stage, recovery possible with little or no lasting effects
compensatory
Metabolism changes from aerobic to anaerobic (buildup of lactic acid cannot be removed by liver due to decreased tissue perfusion)
initial
Impaired GI motility increases risk for paralytic ileus
compensatory
Sustained hypoperfusion causes weak peripheral pulses and ischemia of distal extremities
progressive
Fluid moves into alveoli, causing edema, decreased surfactant, worsening V/Q mismatch, tachypnea, crackles, and increased work of breathing
progressive
Hypoperfusion–>renal tubular ischemia–>AKI (worsened by nephrotoxic drugs), decreased urine output, increased BUN, increased creatinine, metabolic acidosis
progressive
Causes cool, clammy skin
compensatory
Helps maintain homeostasis
compensatory
Shunting blood from lungs increases physiologic dead space, which results in V/Q mismatch, decreased arterial O2, increased rate/depth of respirations
compensatory
Increased capillary permeability, profound hypotension/hypoxemia, worsened tachycardia
refractory
Stage in which patient is in ICU for advanced monitoring/treatment
progressive
Attempt to overcome consequences of anaerobic metabolism
compensatory
Exacerbation of anaerobic metabolism causes accumulation of lactic acid
refractory
liver fails to metabolize drugs and waste, causing jaundice, increased enzymes, decreased immune function, and increased risk for DIC and significant bleeding
progressive
Vasoconstriction and maintenance of blood flow to vital organs (heart, brain)
compensatory
Characterized by decreased cellular perfusion and altered capillary permeability
progressive
Baroreceptors in carotid/aortic bodies activate SNS in response to decreased BP–> increase in myocardial O2 demands
compensatory
