2 places FDA approved for IO
proximal/distal tibia
humeral head
benefit of humoral head IO
can get 6L/hr vs 1L/hr w. tibia
2 indications for IO

4 contraindications for IO
active infxn
broken bone
any titanium
IO in that area in the last 72 hr
what does FAST stand for
facial droop
arm drift
speech
time last seen normal
optimal time for stoke outcome

pulseless electrical activity
tx for pea
push hard and fast

hypoxia
hypovolemia
can atropine treat high grade heart blocks
no!
3 causes of high grade heart blocks
meds
SSS
heart transplant
how do you know when trans pacing is working
all pacer spikes will be followed by QRS
can adenosine treat aflutter/afib/wpw
no!
what should you do post trans pacing
check for pulse

expert opinion
when should rescue breathes be given
1 breath q 6 sec
3 steps if you find unconscious pt
check responsiveness
activate ERS/get defibrillator
check breathing/pulse
if unresponsive pt does not have a pulse you should
give 1 breath q 6 seconds
what should you do if an unresponsive pt has no pulse
start CPR
check rhythm/shock if indicated
how often should rhythm be checked/shock administered
q 2 min
4 steps for acute stroke management
obtain vitals/ABC intervention
