This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

Based on that EKG, the fediverse is in some sort of v-tach and blood is not pumping efficiently enough to have a pulse
We need to turn it off and on again.
Fun fact for anyone reading who doesn't know: if you're ever in the room while someone is being defibrilated, make sure you're not touching them in any way. The electrical shock can stop your heart too!
My department only does this to brains though.
Nah. Defibrillators use direct current. Unless they are covered in salt water, there is no reason for the electricity to go anywhere other than in a relatively straight line
If you have two resistors in parallel the current doesn't just flow through one resistor. You will get shocked. That's why you yell "clear" before juicing them.
No. You yell clear before defibrillation because of hypothetical risk. The likelihood that a person actually received a significant shock is tremendously low, and even lower if they are wearing gloves.
As a side note, you do not yell clear before juicing them. You charge the defibrillator while continuing to give cpr, and then once it is charged, you clear, analyse the rhythm, and if it is shockable, ensure everyone is clear and deliver the shock. This protocol is to minimise the amount of time the arrested patient goes without chest compressions.
TIL
Electricity doesn't immediately know where to go. It is true that it will always take the shortest path to ground, as soon as it finds that route. This is extremely simplified.
