1. A system comprising:
a communications interface to receive data streams from a plurality of physiological sensors, each of the plurality of sensors measuring a different physiological parameter of a patient;
at least one programmable data processor; and
memory storing instructions which, when executed by the at least one programmable data processor, result in operations comprising:
receiving one or more data streams from each of the plurality of physiological sensors via the communications interface, the one or more data streams comprising varying values generated by the sensor and characterizing the associated physiological parameter;
determining, at least once every second, and for each of the plurality of physiological sensors, a parameter score;
wherein determining the parameter score comprises, for each of the plurality of physiological sensors:
calculating a magnitude of a plurality of varying values generated by the physiological sensor;
determining which of a plurality of predetermined ranges the calculated magnitude falls into;
allocating a predetermined factor to the calculated magnitude according to which of the plurality of predetermined ranges the calculated magnitude falls into, the allocated factor being added to a time-average of allocated factors over a time window and used to generate the parameter score determined for the sensor, wherein the plurality of predetermined factors are the same for each of the plurality of physiological sensors;
generating, at least once every second, a patient health index, by combining the parameter scores determined for each of the plurality of sensors to characterize an overall health of the patient; and
providing, at least once every second, data characterizing the patient health index.
