Advanced Life Support Flashcards
effective chest compressions are done at what rate per min?
100-120 per minute
what depth should chest compressions be?
5-6cm
what should you make sure you do after pushing down on the chest?
allow effective recoil of the chest after the compression
what oxygen flow rate should be administered for a pocket mask?
6-8l per minute
when is the only time oxygen should be removed during CPR
when standing clear for defibrillation
name the 4 H reversible causes of cardiac arrest
hypoxia
hypovolaemia
hypo/hyperkalaemia
hypothermia
name the 4 T reversible causes of cardiac arrest
thrombosis
tamponade
toxins
tension pneumothorax
Ix for hypothermia
low reading thermometer
Tx for hypothermia
dry clothes
warm up fluids
name becks triad for cardiac tamponade
hypotension
raised JVP
muffled heart sounds
“pinpoint pupils”
opioid pupils
symptoms of opioid toxicity
respiratory depression
pinpoint pupils
symptoms of carbon monoxide poisoning
tachycardia
hyper/hypotension
pallor
symptoms of cyanide poisoning
bradycardia + hypertension
then tachycardia, hypotension and red skin
“cherry red skin”
cyanide poisoning
when should IV adrenaline be started if the patient is in VF/VT?
after 3rd shock during chest compressions
when should IV adrenaline be started if the patient is in asystole
as soon as IV access is achieved
how often should IV adrenaline be given if treatment is decided?
every 3-5mins during alternate cycles of CPR
why do you give adrenaline in an unconscious patient
increases chance of restoring circulation by vasoconstricting BVs to increase perfusion and augment venous return
what ventilation rate should be given using an advanced airway?
10 breaths per min
when are the only times that chest compressions should be interrupted?
when standing back for defibrillation
when the patient shows signs of spontaneous circulation
the dial on the defibrillator should be set to __J
150
the 2 shockable rhythms are…
VF
pulseless VT
what number on the defibrillator should be pressed to shock the patient
3
the 2 non-shockable rhythms are…
pulseless electrical activity
asystole
