Template:Compartment Pressure Interpretation

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
