Claim One:
1. A patient monitoring system for determining a risk of mortality of a patient located in an intensive care unit, the system comprising: a plurality of medical sensors connected to the patient each configured to measure a physiological parameter and transmit related physiological data of the patient, the plurality of medical sensors including: a blood pressure medical sensor configured to measure a blood pressure physiological parameter, and a heart rate medical sensor configured to measure a heart rate physiological parameter; and a patient monitor communicatively coupled to the plurality of medical sensors and a hospital system, the patient monitor including: a user interface configured to receive an identifier of the patient, a data collector configured to periodically receive the physiological data from the plurality of medical sensors including blood pressure physiological data and heart rate physiological data, a mortality risk engine operating a mortality statistical model that is configured to determine the risk of mortality of the patient by: aggregating the physiological data from the medical sensors into regular defined time intervals related to when the physiological data was generated, and determining an ongoing risk of mortality of the patient, for each defined time interval, by: (i) determining composite variable data from a transformation, derivative, or combination of the physiological data from the medical sensors, (ii) identifying model parameters of the mortality statistical model that correspond to the composite variable data and the physiological data, (iii) for each identified model parameter, identifying at least one significant fatal interval that has a numerical range of values and a mortality weight that is predicative of a fatal outcome for the patient for data that falls within the numerical range, (iv) for each identified model parameter, determining there exists at least one significant non-fatal interval that has a numerical range of values and a mortality weight that is predicative of a non-fatal outcome for the patient for data that falls within the numerical range, (v) for each identified model parameter, determining if the composite variable data or the physiological data that corresponds to the identified model parameter falls within the at least one significant fatal interval or the at least one significant non-fatal interval, (vi) for the identified model parameters where the corresponding data from (v) falls within one of the intervals, averaging the mortality weights of those intervals to determine the risk of mortality of the patient, and (vii) for the identified model parameters where the corresponding data from (v) does not fall within one of the intervals, discarding the corresponding data from consideration for determining the risk of mortality of the patient, and a display interface configured to display the ongoing risk of mortality in numerical or graphical form in conjunction with at least some of the physiological data from some of the plurality of medical sensors.
