A

brachial, femoral

18
Q

A

vtach and vfib
2-4J/kg
repeat with 4j/kg

22

SVT
aflutter and afib
0.5-2J/kg
repeat 2J/kg

23
Q

What medications can be delivered through an ETT?

A

NAVEL
naloxone
atropine
vasopressin, valium
epinephrine
lidocaine

24
Q

A

anterior tibia

25
Q

Describe care after ROSC

A

titration of FiO2 to maintain pulse ox levels form 94-99%
assess for rebound of arrest
assess for ETT and line displacements
avoid hyperthermia, hyperglycemia, and seizures
accurate reporting to surgery team, family, ICU team

26
Q

What is the dose of Epi infusion after arrest?

A

0.05-1mcg/kg/min
inotrope, chronotrope

27
Q

What is the dose of dopamine after arrest?

A

2-20mcg/kg/min
inotrope, chronotrope, dilates splanchic vasculature at. lower doses, pressor effect at higher doses

28
Q

What is the dose of dobutamine after arrest?

A

2-20mcg/kg/min
inotrope, decreaseds SVR

29
Q

What is the dose of milirnone after arrest?

A

load 25-50mcg/kg
infusion: 0.5-1mcg/kg/min
inotrope, improves diastolic relaxation, decreases SVR
