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
