what does release of histamine in the body do
increase HR
vasodilation -> decreased BP
bronchoconstriction
increased gastric acid -> N&V
what does epinephrine help with
vasopressor (increase BP)
dilate airways
increase heart ability to pump blood
alpha/beta adrenergic agonists (receptor)
what are the requirements for SIRS (systemic inflamatory response syndrome)
Temp: <96.8 to >100.4F
Resp rate: >20
Heart rate: >90
WBC: > 12,000 or <4,000 &
>10% neutrophile bands
abnormal neutrophil range and band
50-70% normal >70% abnormal
0-8% normal >10% band abnormal
when to give antipyretic
> 102F
what conditions would the pt considered to be in sepsis
2 SIRS requirements
confirmed or suspect active infection
what condition is considered to be severe sepsis
confirmed sepsis, signs of end organ damage
Hypotension 120/80 normal (<90)
Lactate >4 mmol
what is considered septic shock
severe sepsis with persistent signs of end organ damage, hypotension, lactate >4 mmol
what does qSOFA score tell you
screen the likelihood of a pt having sepsis
list infections that are most commonly associated with sepsis
pneumonia
GI infections
