ALS Flashcards
shockable and non shockable rhythms

when to give amiodarone and adrenaline
after 3rd shock in VF/pulsemess VT
PEA/Asystole drugs
give 1mg adrenaline ASAP
PErcentage survival cardiac arrest in hospital
24%
surviva out of hospital cardiac arrest
10%
most common in hopsital cardiac arrest rhythim
PEA
normal t wave inversion on ecg leads
aVR, v1, lead III
NSTEMI ecg signs
t wave inversion - in v2-v6 leads
ST depression also in ant leads and lateral leads
post resus care— temp aim
can be initiated in the average Dr by rapid infusion of 2 litres of ice cold crystalloid solution and the target temperature is 32 - 36°C.
tachycardia number
over 100bpm
drugs for rate control
beta blocker
(diltiazem if b blocker CI’d)
Digoxin
drugs rhythm control
flecanide
amiodarone
post cardioversion for AF- how many weeks of anticoag
4 weeks min
what to do if cardioversion does not terminate tachycardia after 3 attempts?
iv amiodarone 300mg and try cardioverting again
contraindicated in asthma
adenosine
beta blocker

Tricyclic antidepressant overdose ecg
tricyclic antidepressant. The ECG shows a tachycardia with broad QRS complexes
TCA overdose treatment
activated charcoal if the overdose is within 1h
consider 50 mmol L-1 of sodium bicarbonate
consider prescribing 50 mmol L-1 of sodium bicarbonate
TOXBASE
how much adrenaline adult anaphylaxis
500micrograms of 1mg/ml 1:1000 adrenaline
when not to give bendroflumethiazide in benzo overdose
in pts with seizures
If the pH decreases below 7.35, with a high PaCO2, this is called ??
resp acidoses
pH increases above 7.45, with a low PaCO2, this is called a respiratory alkalosis.
resp alkalosis

120-150 JOULES
how does end tidal vol change on ROSC
it increases
do not use which airway adjunct in concious pt
do not use guedel in consious pt
