CPR

Question 1

RECOVER

Answer 1

5 domains -
preparedness and prevention
basic life support (ABC)
advanced life support (DEF)
monitoring
post cardiac arrest care

classes - indicate whether an intervention should be performed (1-3)
levels - how well the intervention is supported as being effective in literature (a-c)

Question 2

clinical signs of pulmonary arrest

Answer 2

discoloured blood or cessation of bleeding
gasping or apnoea
high CRT
discoloured mms
no heart sounds or palpable pulse
central eye
mydriasis (dilated pupils)
cranial nerve arreflexia
muscle relaxation

Question 3

ABCDEF

Answer 3

A - airway
B - breathing
C - circulation
D - drugs - adrenaline/atropine - 2x low dose, 1x high
E - electrical stimulation
F - follow up

Question 4

CPR algorithm

Answer 4

right lateral recumbancy

1 cycle - 2 mins
- 100-120 compressions/min, 1/3-1/2 chest width
- ventilation - 10/min
- initiate monitoring - ECG and ETCO2

check

asystole - continue for another cycle
vfib - continue while charging defibrilator, give 1 shock, continue CPR

check

repeat until cardiac activity resumes or give up

Question 5

Monitoring

Answer 5

look for pulse - don’t take more than 10 seconds between compressions
ECG for rhythm evaluation
end tidal CO2 - tells you when to ventilate and when to switch to another person, CO2 will jump up if normal function returns
blood-gas and electrolyte analysis - helpful in identifying underlying causes

Question 6

cardiopulmonary arrest contributing factors

Answer 6

myocardial disease
hypoxia
extreme temperature or pH
altered electrolytes
toxemia
