In brief: See below

Skin ulcers are often staged based on depth (stage 4 = deepest).
.. Stage 1: reddened skin that does not blanch (doesn't turn white when pressed). Stage 2: superficial erosion of the skin -- often appears as an abrasion, blister, or shallow crater. Stage 3: full thickness skin loss to the level of fat. Stage 4: full thickness skin loss + involvement of underlying structures (e.g. Muscle, bone, etc).

Bed sore is an old fashioned term for pressure ulcer. The newer term is preferred because it denotes the cause of sore. This abnormal pressure that leads to ulcers can happen in persons who are not bedridden so it is more helpful to understand that anything causing increased pressure ( poorly fitting brace for example) can cause an ulcer.

In brief: Loss all layer skin

Stages describe the depth of the sore at the time of examination.
Stage i - skin is intact which if untreated will become and open sore stage ii - abrasion, blister or ulcer going partially through skin stage iii - crater through all layers of skin into fatty layer stage IV - through all layers of skin and fatty layer into muscle, bone, tendon or joint space.

In brief: Pressure Ulcer

I refer you to www.
Npuap.Org for the most accurate descriptions of ulcerations. A stage IV ulcer means that at the bottom of the skin opening, you can see bone, muscle and/or tendon.
