ACLS Flashcards
Class III anti-dysrhythmic potassium channel blocker?
Amiodarone
Dosage and route of amiodarone?
Pulseless: 300 mg IV push for refractory VT and VF
With Pulses: 150 mg IV push for wide complex VT.
Hs and Ts
Hypoxia Hypothermia Hydrogen ions (acidosis) Hypo-/Hyperkalmia Hypovolemia Thrombus (cardiac/pulmonary) Toxins Tension pneumothorax Tampinode, cardiac
Epineprine
Sympathetic agonist, naturally occurring catecholamine with alpha and beta stimulant effects. Effects on beta-receptors is more profound than on alpha-receptors.
Effects of epinephrine?
Increased heart rate Increased cardiac contractile force Increased electrical activity in the myocardium Increased systemic vascular resistance Increased blood pressure Increased automaticity
Epinephrine dosage for cardiac arrest
1.0 mg of 1:10,000 IV or IO push (can be repeated every 3 to 5 minutes).
Endotracheal dosage increased by 2 to 2.5 times IV dosage.
CPR Quality
Push hard (2 inches or more) and fast (100 or more per minute) and allow complete chest recoil.
Compression to Ventilation Ratio
30:2 compression-ventilation ratio if no advanced airway is in-place.
Return of Spontaneous Circulation (ROSC) pETCO2
Typically 40 mm Hg or more.
Atropine
Anticholinergic, parasympatholytic (anti-cholinergic) derived from parts of the Atropa belladonna plant. It is used to increase the heart rate. It has positive chronotropic effects with little to no inotropic effects.
Amiodarone indications?
Stable, irregular, narrow-complex tachycardia (A-fib)
Stable, regular, narrow-complex tachycardia
To control rapid ventricular rate due to accessory pathway
Amiodarone contraindications?
Cardiogenic shock
Sinus bradycardia
2nd and 3rd degree AV block
Atropine indications are…
hemodynamically significant bradycardia with a pulse.
Atropine contraindications are…
none emergency situations. Be cautious of coronary artery disease, 2nd and 3rd degree AV blocks.
Atropine side effects are…
blurred vision, dilated pupils, dry mouth, tachycardia, drowsiness, and confusion.
