There is an armour pick up by the stairs leading to the third floor, I think. There's a first aid kit on the ground level - you can't miss it as you have to go past it. Then there's a second on the wall on the third floor.
If necessary, the first aid kit on the ground floor respawns so you can clear out a floor and then go get some health.
