Interpretation of Compartment Pressure
- 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] – [Compartment Pressure][1]
- ΔPressure < 30 mm Hg is suggestive of compartment syndrome
