Japan earthquake

Pretty sure the carts have locking wheels for a reason ?

Not an earthquake. The AI powered medical equipment became sentient and decided to start a square dance.

That's actually terrifying...... One last step before swapping a heart and all of the life support blood pumps rip out of the body , now there's an empty fucking chest, the new heart is flipping around the floor , the anesthetic pipe is ripped out , and fish head on the bed wakes up , chest open, no heart wondering wtf is going on.
