Final Blueprint Shock/Sepsis Flashcards
what is the patho of sepsis?
Infection occurs in the body (i.e. UTI, pneumonia, COVID)
Immune response is triggered (but gets out of control)
Inflammatory mediators and cytokines released into the blood which cause:
-Vasodilation: low volume
-Capillary leak: edema and low volume
-Blood clotting: blocked vessels
Organ damage occurs due to O2 starvation
Metabolic acidosis occurs due to organ disfunction (pH low; CO2, lactic acid, bicarb high)
Septic shock: when sepsis is resistant to fluid resuscitation (30mL/kg/H)
Multi-organ dysfunction syndrome: 2 or more organs have failed
what are the nursing interventions for sepsis?
Rapid fluid bolus (30 mL/kg)
Draw blood cultures BEFORE starting ABX
Broad spectrum ABX until cultures are done
Vasopressors to maintain MAP >65
Passive leg raise
what is shock?
decreased perfusion (hypotension - decreased CO - organ failure - death)
what are the stages of shock?
Initial stage: not enough O2 to perfuse the organs, asymptomatic
Compensatory stage: HR and RR increase, renin and angiotensin released to try to balance, organs begin to fail
Progressive stage: progressive poor perfusion leads to cold and clammy skin
Irreversible stage: death
What is sepsis shock?
Hypotension (SBP <90)
Cool and clammy skin - blood is being redirected to vital organs
Delayed cap refill
Mental status changes
Temp = very high or very low
Low urine output
WBC >10,000
Lactate >4
