Now we're gonna get into the algorithms. This is the pinnacle of the course. The algorithms are going to tell us what to do and when to do it with drugs and electricity for people that are alive and for people that are in cardiac arrest. So the algorithms that we're going to go over are going to be cardiac arrest bradycardia, tachycardia, and post arrest care. So right now, let's focus on cardiac arrest. There are basically two types of monitors or two febrile seizures that we can use for cardiac arrest.
Just know that you have monophasic defibrillators and by phasic defibrillators, there is a difference the monophasic defibrillator the highest jewel setting is 360 joules and what that does is it sends electricity in one direction only from pad to pad 360 joules the by phasic to fibrillation is much more common in the house. Little setting, and that highest jewel setting is 200 joules. So that difference is it's sending electricity in both directions from pad to pad. But regardless whether you have a biphasic or a monophasic defibrillator, we want to turn it all the way up. We want to be at the highest setting possible during cardiac arrest, it's going to be what's best for the patient. The drugs or the medications that we're going to use for cardiac arrest.
The first one epinephrine, we're using it on everybody. Just remember he everybody gets epi, epinephrine, his job is to vasoconstriction those vessels and if we can get the vessels to be smaller, we can send you know, oxygen, blood and medications to the parts of the body that needed the half life is about three to five minutes. So we can push it as many times as we need to. During that cardiac arrest. There's no maximum dose, but we want to push it every three to five minutes during that cardiac arrest regardless of what rhythm they're in. Just remember he everybody gets epi The next medication is me odor on me Oh drone is considered to be an anti arrhythmic medication.
And for cardiac arrest, we only have two doses. The first dose is 300 milligrams. And the second final dose is 150 milligrams. Now, me odorant can only be used on shockable rhythms because it's an anti rhythmic. So the two arrhythmias for cardiac arrest that are shockable, that we can use mo drone are our V fib, pulses v tac, they both have that V in there. Fantastic.
So mo drones job is actually to calm the heart down. And if we can stop it from quivering so much. It tends to accept the electricity and the drugs and the CPR just a little bit better to calm the heart down. But we only have two doses of it. They'd like us to push me around every three to five minutes as well. But we're going to push the opposite of epinephrine.
We shouldn't push epi and MBO together because the heart goes Hey, what are you trying to do to me, I'm going to look crazy here. So I want to let them Each do their job every three to five minutes opposite of each other. And keeping in mind we can only use me or don't if it's a shockable rhythm, if me Oh, don't is not available. Light a cane has indicated pretty much does the same thing as me. Oh, Tarun, it depresses the the function of the purkinje fibers, and it just makes the heart less likely to, to quiver. So if you don't have ammo, you can go with lighter cane.
Now your cardiac arrest cycle we mentioned a little bit earlier, it's always a two minute cycle. So the two minutes cycle on the cardiac arrest is just going to keep spinning every two minutes. While we check everything off, starting at the top and working our way down to the bottom. The only time we should stop that cardiac arrest is they are treating the cardiac arrest obviously is if the patient wakes up and says, Hey, get off my chest fine, we should stop. Or if we've done it so long are we just not going to continue the resuscitation attempt on that patient then we can just call the code but other than that, we're gonna keep doing CPR. Until they wake up what we call the code
