1. A patient survivability prediction system comprising: a first input to receive a first set of parameters relating to heart rate variability data of a patient; a second input to receive a second set of parameters relating to vital sign data of the patient; a memory module to store the first set of parameters and the second set of parameters; at least one processor coupled to the memory module and configured to analyze the first set of parameters and the second set of parameters and output a prediction on the survivability of the patient over the next 72 hours based on the first set of parameters and the second set of parameters; and a display coupled to the at least one processor to display the prediction on the survivability of the patient over the next 72 hours.
