Heart Rate Variability in Trauma Patients

The eligible study population will be comprised of patients who meet level 1 trauma criteria and are transported by helicopter to Ryder Trauma Center or who are already admitted to the trauma center for presumptive traumatic brain injury. In addition to the EKG, trauma patients may also be connected to either an non-invasive NIR Monitor, which provides real-time information about perfusion status and/or a bispectral EEG monitor, which provides real-time information about brain metabolic activity.
