What exactly can be considered ''very low health''?

[Ynf]

For that one achievement I need to end a level on very low health, the lowest I have gotten is 10, which I would call pretty low. That wasn't enough though, can anyone tell me what amount of health I need to get, and what enemies can make it so?
