Disclaimer: Im not familar with D2 in any way.

With that said, I know this much, D2 is a game with graphics.  Those graphics are rendered, to render them there is a loop that draws each frame.  It may be easier for you just to place a call to your function that checks the current life of the character in the primary rendering loop of the game.
