Pulseless VF/VT Review Questions Part 4 31.   What are the initial and subsequent joule settings when defibrillating a patient with a monophasic defibrillator? 32.   In order to maintain rescuer safety, should CPR be interrupted while the defibrillator is charging? 33.   Biphasic defibrillators are effective at terminating VT over a variety of joule settings.   If you do not know the manufacturer’s effective biphasic dose setting, what joule setting should you use? 34.   What should you do if VF is terminated by a shock but later recurs in the resuscitation attempt? 35.   After delivering a first shock at 200 J, you note that the patient remains in refractory VF.   What should you do next? 36.   What should the rescuer do as he/she is clearing the patient prior to delivering a shock? 37.    Why is it necessary to use conductive gels when using defibrillator paddles? 38.   When treating a cardiac arrest pati...

Drug Therapy: Magnesium Sodium Bicarbonate Magnesium 1-2g diluted in 10cc of NS IV/IO push Circulate drug with CPR for up to 2 minutes Defibrillate at 200J or higher and analyze rhythm Indicated for hypomagnesemia Indicated for Torsades de pointes Sodium Bicarbonate 1mEq/kg IV/IO push Circulate drug with CPR for 30-60 sec. Defibrillate at 200J or higher and analyze rhythm Not given routinely.  (Treate respiratory acidosis with adequate ventilations) Indications: long arrest interval, ASA OD, Tricyclic OD, Know metabolic acidosis Follow Up   Note:  If the patient has ROSC, post–cardiac arrest care should be started. Of particular importance are treatment of hypoxemia and hypotension, early diagnosis and treatment of ST-elevation myocardial infarction (STEMI) (Class I, LOE B) and therapeutic hypothermia in comatose patients (Class I, LOE B).

Drug Therapy: Antiarrhythmics Amiodarone Lidocaine Note When VF/pulseless VT persists after 2 to 3 shocks plus CPR and administration of a vasopressor, consider administering an antiarrhythmic such as Amiodarone.   If Amiodarone is unavailable, Lidocaine may be considered. Consider magnesium for torsades de pointes associated with a long QT interval. You should administer the drug during CPR, as soon as possible after rhythm analysis Amiodarone ·          First antiarrhythmic ·          Initial dose 300mg IV/IO diluted in 20cc of NS or D5W ·          May repeat in 5 minutes with 150mg IV/IO diluted in 20cc of NS or D5W       ·          Max dose 2.2g/24h After 2 minutes of CPR defibrillate at 200J or higher and analyze the rhythm Note: Amiodarone is the ...
