Certain
The slide coming out of the patient's heart is there because a mad scientist is testing to see if it's a good way to drain the body of blood. The patient is alive now... but they are definitely slated for certain death.
As you imagine the mad scientist drawing blood out of the patient's heart with a small slide, also imagine a little meter hooked up to him as well. On one end is "SURVIVE!" on the other end is "CERTAIN DEATH." Right now the finger is pointing close to certain death, though :(
ひつ
かなら
None
As the beeping heart thing starts to do one long continuous beeeeeeeeeeeeeep, the doctor puts his hands together and hits (ひつ) the dead patient over and over, attempting to bring him back.
Maybe imagine yourself running in there too, just trying to hit the patient back to life, because the patient was your friend.
