Equipment Needed
Procedure
- Contents of the pressure measurement kit
- Remove contents from wrapping
- Attach chamber to the pre-filled saline syringe
- Place the aforementioned into the monitor/unit
- Place needle onto chamber
- Eject excess air, if present, from syringe
- Zero the assembled unit at the angle you will be entering compartment
- 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
