Healing

Each body part has its own health. Damage also causes status effects that a normal heal doesn't fix. Below is what fixes what, straight from the item data.

Light bleed: slowly drains health. Fix with a bandage or a medkit.
Heavy bleed: drains health fast. Fix it right away with a tourniquet, hemostat or a medkit that cures it.
Fracture: you limp or shake. Fix with a splint (or a surgical item that cures it).
Pain: blurry screen and shaking. Painkillers hide it for a while.
Blacked-out limb (0 health): only a surgical kit restores it; afterwards that limb has lower maximum health for the rest of the raid.
