Catheter OMNIBAR E5F for Exact Compartment Pressure Measurement Precise pressure measurement for early detection of compartment syndrome

The compartment syndrome is a dysfunction of the blood circulation in the muscle compartments. A muscle compartment consists of several functionally joined muscle groups that are enclosed by a membrane made of firm connective tissue (muscle fascia). Inside the compartment there are also blood vessels and nerves. Since the muscle fascia is not very flexible, a swelling inside the muscle compartments caused by lack of space will lead to increased tissue pressure in the compartment so that nerves and blood vessels are constricted. The result of the compartment syndrome is an undersupply of oxygen in the muscles.

The sterile  catheter OMNIBAR E5F measures the pressure inside the compartment at rest, during a stress test and after the stress test. The difference in these 3 pressures can confirm the diagnosis.

Intramuscular Tissue Pressure Measuring (IMP) Catheter

  • Outside diameter: 5F
  • Catheter length: 55 cm
  • Material: PU

There are 3 Different Possible Set Ups for Pressure Measurement:


The battery operated NPS3 device in connection with a ICP-TEMP-Cable, which serves as an extension cable


For long-term measurements: One end of the NPS2 connects directly to the patient monitor and the other end is connected to the ICP-TEMP-Cable (extension cable)


Via MPR 1 DATALOGGER in connection with the ICP-TEMP-Cable three IMP-pressures in the healthy and ill tissue can be measured and compared
