Normal is <10 mm Hg
Pressures <20 mmHg can be tolerated w/o significant damage
Exact level of pressure elevation that causes cell death is unclear.  It was previously thought pressure >30 mmHg was toxic although the "delta pressure" may be better predictor than absolute pressure
ΔPressure = [Diastolic Pressure] –<unk>  Pressure]
ΔPressure < 30 mm Hg  is suggestive of<unk>
