Near-Infrared Spectroscopy versus Compartment Pressure for the Diagnosis of Lower Extremity Compartmental Syndrome Using Electromyography-Determined Measurements of Neuromuscular Function

BackgroundCompartmental syndrome (CS) is difficult to diagnose in intensive care unit patients. Compartment perfusion pressure (CPP) is an invasive, indirect measure of ischemia. Near-infrared spectroscopy is noninvasive, and directly measures ischemia by transmitting light through tissues at wavele
