In a code situation a paient is found in asystole. CPR is performed and resucue meds are given. Approximately 5 minutes have elapsed and you see V-fib on the monitor is that then a shockable rhythym?

Yes the only unshockable rhthym is no rhthym such as asystole and PEA but some will agrue to shock aststole because it might be fine VF.

I don't think there was a pulse, so I take it we were still not to shock even if it showed V-fib on the monitor?

If it was v-fib on the monitor, then shock it. one of the purposes in giving epinephrine during a code is to alter the fibrillation threshold, in order to produce a more shockable rhythm. remember coarse v-fib is typically more responsive to electrical therapy than fine v-fib. the flatter the line...the longer they have been fibrillating.

yes, then the algorithm has changed as well.

Yes of course, if you ever see VF, shock it.

Yes, definitely a shockable rhythm

You won't generally have a pulse with V-tach either, and you still shock that. If you get v-fib back after asystole consider yourself lucky and add electricity ASAP. If you are really lucky you will continue the progress

What would you do if you saw V-tach with no pulse, which commonly happens? V-fib is a shockable rhythm even with no pulse. The patient is dead, and without intervention he or she is going to remain that way.

I don't really understand your question. VF (or rapid VT) most commonly does not have a pulse, because the heart is beating/filbrillating too fast to fill and empty properly and create a pulse.

The purpose of defibrillating is to disrupt that rhythm and restore the electrical (and hence mechanical) firing.
