Check out my party health after this battle

I already had considerably low health in a few of my party members, and was planning on resting to heal up before further exploring - but then I accidentally tripped detection from a room of guards by walking past the open doorway without sneaking. There are 3 visible on the ground, but there might be another hidden by the hallway's lower walls, I can't remember. I'm playing Hard difficulty, and I felt I'd pushed my party health as much as I'd get away with before this surprise fight.
