A 40-year-old man arrives at the ER accompanied by his family. He is complaining of palpitations after working outside for several hours. The assessment is as follows:

SKIN: Hydrated, pale, warm and dry
CVS: Strong peripheral pulses and a BP of 125/80
CNS: Fully intact
RESP: RR is 22, no resp. difficulties, lungs CTA

You start an IV on the patient. The monitor shows a narrow complex SVT (160).

What is your next intervention?

You have performed vagal maneuvers. This is what you see on the monitor:

What is your next step?

You give 6mg Adenosine rapid IV push with no effect. 12mg Adenosine rapid IV push is then given. The patient develops severe chest pain, his rhythm is the same, and his vital signs are: HR 220, BP (not obtainable), and weak pulse. The patient also has LOC changes. Your next step should be?

After synchronized cardioversion is unsuccessful, the pt. continues to deteriorate. The patient is now unconscious with pulseless ventricular tachycardia. Below is what you see on the monitor:

What is the first and most important intervention?

You perform defibrillation with 120 J. What is your next intervention?

After completing 5 cycles of CPR, the rhythm is unchanged. You shock a second time with 200 J and resume CPR. While completing the cycle of CPR what else should be done?

You have given the epinephrine and completed the 5 cycles of CPR. A rhythm check reveals no change. You attempt a third defibrillation. What will be your defibrillator setting?
(In all scenarios, assume that the biphasic defibrillator shock setting can be from 50-360 Joules. The shock selection on many biphasic defibrillators can vary.)

The third shock is delivered and you restart CPR (5 cycles). What medication should be given after the 3rd shock during CPR?

What is the correct dosing for amiodarone in the Cardiac Arrest Algorithm?

You give amiodarone 300 mg (first dose) and finish the cycle of CPR. Upon a rhythm check, you see, the patient has converted to a normal sinus rhythm and has a pulse (ROSC). As you begin the post-arrest phase, the patient has a short run of VT. In light of the continued arrhythmia, you are instructed to start an amiodarone drip for post-resuscitation maintenance therapy. What is maximum cumulative dose for amiodarone in a 24 hour period?

Lidocaine can be used instead of amiodarone as an antiarrhythmic during cardiac arrest. What is the proper dosing of lidocaine?

Great Job! You saved the patient He has been stabilized and intubated, but does not respond to verbal commands. He is transported to the hospital’s ICU. Since the patient is not responsive what would be the most important intervention in the post-cardiac arrest phase.
