• Dosing of epinephrine in the setting of VF/pVT and asystole/PEA

Answer: 1 mg every 3-5 minutes

• Dosing of amiodarone (first and second dose) in the setting of

cardiac arrest

Answer:

300mg first dose 150mg second dose after 3-5 min

• 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

• What is the maximum dose of lidocaine?

Answer: 3 doses or 3mg/kg

• ROSC is typically signified by a PETCO2 of what?

Answer: 40 mm Hg or more

• The "Hs" of reversible causes of cardiac arrest

Answer:

• Hypovolemia
• Hypoxia 1 / 4

• Hydrogen ions (acidosis)
• Hypo/hyperkalemia
• Hypothermia

• The "Ts" of reversible causes of cardiac arrest

Answer:

• Tension pneumothorax
• Tamponade, cardiac
• Toxins
• Thrombosis, pulmonary
• Thrombosis, coronary

• 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 airway is in place?

Answer: 6-8 seconds (8-10 breaths/min) with continuous chest

compressions

• If PETCO2 falls below , attempts should be made to

improve chest compressions

Answer: 10

• If intra-arterial pressure monitoring is being utilized during a

resuscitation attempt, if the diastolic pressure falls below mm Hg, attempts should be made to improve chest compressions

Answer: 20

• depth of adequate chest compressions

Answer: 2 inches

• / 4

• rate of adequate chest compressions

Answer: 100-120/min

• If no advanced airway is in place, what is the ratio of chest

compressions to ventilations?Answer: 30:2

• Shock energy that should be used on a biphasic machine for

defibrillation

Answer: 120-200 J, if recommended setting not known, use

maximum available

• Shock energy that should be used on a monophasic machine for

defibrillation

Answer: 360J

• In the setting of cardiac arrest, when should vasopressors be

administered?

Answer: after the patient has failed CPR and defibrillation (shock-

refractory arrhythmias)

• The only vasopressor recommended in the cardiac arrest

algorithm

Answer: epinephrine

• 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 3 / 4

• Are higher doses of epinephrine recommended in certain

situations of cardiac arrest? If so, what situations are higher doses of epinephrine recommended?

Answer: no; no benefit to support use, possible harm

• When is endotracheal medication administration recommended?

Answer: not rec ommended unless unable to give meds IV or IO

• Which medications can be administered via endotracheal tube?

Answer: lido caine, epinephrine, atropine, naloxone

• What is different about the dosing of medications if

endotracheal medication 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

• 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

• Why must antiarrhythmics never interfere with CPR and shocks?

Answer: never been shown to increase survival to discharge

• Antiarrhythmics that could be considered in the setting of

VF/VT

Answer: amiodarone and lidocaine

• / 4
