heart stops pumping blood
respiratory arrest
pt unable to breathe
American Heart Association
CPR with in 4 mins
high survival rate
ACLS
BLS
imaging technologist
epinephrine(adrenaline)
first-line treatment
most valuable
mimics nervous system
produced by adrenal gland
vasopressin(pitressin)
equivalent to endogenous ADH
increases blood flow to vital organs
alternative to epinephrine
dopamine(intropine)
equivalent to endogenous dopamine
stimulates dopamine receptors
second-line therapy
atropine
antimuscarinic agent
inhibits acetylcholine/cholinergenic stimuli at muscarinic receptors
used for slow heart rates
lidocaine(xylocaine)
most frequently used antidysrhythmic drug
blocks sodium channels
treats ventricular dysrhythmias
amiodarone
suppresses dysrhythmias
antidysrhythmic drug
used for pulseless ventricular tachycardia
sodium bicarbonate
strong alkalanizing agent
liberates bicarbonation
treats severe metabolic/respiratory acidosis
