Compensatory Reserve Index as a Hemodynamic Status Evaluation Tool in Patients

The investigators will use the Compensatory Reserve Index (CRI) device to monitor hemodynamic status of patients in the hospital. CRI values of patients will be monitored during their care in order to verify the compliance of the values to the physiological condition. During the protocol investigators will document patients injuries, life-saving procedures performed, response to treatment as well progress to systemic inflammatory response syndrome (SIRS) and sepsis. The indices measured in the study will not be a consideration when handling patients. The medical team will not be exposed to metrics measured.
