Indications

Contraindications

Equipment Needed

Procedure

  1. Contents of the pressure measurement kit
  2. Remove contents from wrapping
  3. Attach chamber to the pre-filled saline syringe
  4. Place the aforementioned into the monitor/unit
  5. Place needle onto chamber
  6. Eject excess air, if present, from syringe
  7. Zero the assembled unit at the angle you will be entering compartment
  8. Insert, inject 2-3 drops of saline, and await measurement

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
