Flashcards in ACLS Deck (18):
Class III anti-dysrhythmic potassium channel blocker?
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
Hydrogen ions (acidosis)
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
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.
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.
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.
Stable, irregular, narrow-complex tachycardia (A-fib)
Stable, regular, narrow-complex tachycardia
To control rapid ventricular rate due to accessory pathway
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.
0.5 mg IV push (can be repeated every 3 to 5 minutes for a maximum dose of 3 mg)
Treatment for high degree heart block...
begin transcutaneous pacing. Target pacing should by 80 joules and 80 bpm.
