Test2: week 5 Flashcards
what are the 6 parts to the chain of survival?
- early recognition and 911 initiation
- early bystander CPR
- early defibrillations in 3-5 mins
- Early ALS
- Post ROSC care
- recovery
the effects of EMS response Increase after 5-6 mins of SCA (T/F)?
False, they effects decrease
compression depth for Adult
2” or 5 cm
pediatric compression depth is
1 1/2” or 1/3 the chest depth
physiology of compressions
compressing the chest cause s an increase in intrathroacic pressure which in turn pumps blood out of the heart and into circulation then allowing the heart to refill again.
what is the rate for adult compressions?
100-120bpm
what is the preffered technique for given peds chest compressions?
circumferential grip with the thumbs at the nipple line.
what is the SBP that compressions maintains?
60-80mmHG
for every min without BCPR for a witnessed sudden VF survival decreases by 7-10% (t/f)
true
how do defib work?
depolarize the whole heat & stops signal transduction in the hopes of the SA node taking over pacing.
what a/w position should we be maintaining for the patient and how do we achieve this?
Sniff position can be achieved by head-tilt-chin-lift or modified jaw thrust. we can also maintain patentcy with the use of OPA/NPA and SGA’s
when should PPV be initiated?
when the patient is apneic or has gasping (aogonal respirations)
during CPR a patients metabolic demand is increased ( true or false?)
false, during CPR a pt metabolic demand is decreased because their is decreased cellular uptake of O2 and O2 delivery.
during CPR CO is 25-33% of what it normally is ( true or false)
true
how much should we be ventilating adult lungs?
500-600ml or till we see chest rise and fall
when checking a pulse it should take less than____ sec
10
what are the landmarks for CPR on an adult?
lower half of the sternum or center of the chest between the nipples at the xiphoid process.
ratio for adult 2 rescuer cpr
30:2
ratio for 2 rescuer peds cpr
15:2
rtio for 2 rescuer neonatal resus
3:1
once an SGA has been put into place breaths should be asynchronous at what rate?
10-12 breaths per min so 1 breath every 5-6 seconds.
