 It's more like a tourniquet.  As long as you have it in place, it works.  Take it off and the bleeding resumes.

Maybe not the analogy you want. Leave a tourniquet on too long without releasing pressure, you lose a limb. Tourniquets also do not work well on head wounds. Maybe a pressure bandage?

I mean, that seems like it makes the metaphor work. We obviously can't SiP indefinitely. At the same time, removing it too soon could be catastrophic too. Threading the needle there is going to be difficult, and largely dependent on the level of care available.
