Dosing of amiodarone (first and second dose) in the setting of cardiac arrest Answer : 300mg first dose 150mg second dose after 3 -5 min 3. Dosing of lidocaine (first and second dose) in the setting of cardiac arrest - Answer : 1-1.5mg/kg first dose 0.5-0.75 mg/kg second dose, repeat in 5-10 min 4. What is the maximum dose of lidocaine? Answer : 3 doses or 3mg/kg 5. ROSC is typically signified by a PETCO2 of what? Answer : 40 mm Hg or more 6. The "Hs" of reversible causes of cardiac arrest Answer : 1. Hypovolemia 2. Hypoxia 3. Hydrogen ions (acidosis) 4. Hypo/hyperkalemia 5. Hypothermia 6. The "Ts" of reversible causes of cardiac arrest Answer : 1. Tension pneumothorax 2. Tamponade, cardiac 3. Toxins 4. Thrombosis, pulmonary 5. Thrombosis, coronary 8. In the setting of cardiac arrest, once an advanced airway is in place, 1 breath should be given every seconds. Should chest compressions be interrupted once an advanced airwa y is in place? Answer : 6-8 seconds (8 -10 breaths/min) with continuous chest compressions 9. If PETCO2 falls below , attempts should be made to improve chest compressions Answer : 10 10. If intra -arterial pressure monitoring is being utilized during a resuscita tion attempt, if the diastolic pressure falls below mm Hg, attempts should be made to improve chest compressions Answer : 20 11. depth of adequate chest compressions Answer : 2 inches 12. rate of adequate chest compressions Answer : 100-120/min 13. If no advanced airway is in place, what is the ratio of chest compressions to ventilations? Answer : 30:2 14. Shock energy that should be used on a biphasic machine for defibrilla tion Answer : 120-200 J, if recommended setting not known, use maximum available 15. Shock energy that should be used on a monophasic machine for defib rillation Answer : 360J 16. In the setting of cardiac arrest, when should vasopressors be adminis tered? Answer : after the patient has failed CPR and defibrillation (shock -
refractory arrhyth mias) 17. The only vasopressor recommended in the cardiac arrest algorithm Answer : epinephrine 18. Why is vasopressin no longer recommended in the cardiac arrest algorithm as a vasopressor? Answer : no additional benefit and may increase delays in medication administration 19. Are higher doses of epinephrine recommended in certain situations of cardiac arrest? If so, what situations are higher doses of epinephrine rec ommended? Answer : no; no benefit to support use, possible harm 20. When is endotracheal medication administration recommended? Answer : not rec ommended unless unable to give meds IV or IO 21. Which medications can be administered via endotracheal tube? Answer : lido caine, epinephrine, atropine, naloxone 22. What is different about the dosing of medications if endotracheal med ication administration is performed? Answer : Typically ETT dose 2-2.5 higher than IV due to lower absorption and dilution in 5 -10mL of fluid is recommended 23. When can antiarrhythmics be considered in the setting of cardiac arrest? - Answer : use may be considered in patients with VF/VT who have failed high-quality CPR, shocks, and vasopressors 24. Why must antiarrhythmics never interfere with CPR and shocks? Answer : never been shown to increase survival to discharge 25. Antiarrhythmics that could be considered in the setting of VF/VT Answer : amio darone and lidocaine
