Compartment Syndromes

elevated CPK,

paresthesia

pain c passive motion

pain c active flexion

tenderness over compartment

compartment pressure >30-35 mmHg is the level most sources site, though this is probably too low to cause ischemia.

More accurate is a level which is greater than 10-30 of diastolic or MAP depending on which study is used.
