Abstract

A medical characterization system is configured to input medical-related continuous parameters and discrete data so as to calculate a characterization timeline indicative of a physiological condition of a living being. A data source is in sensor communications with a patient so as to generate a continuous parameter. The data source also provides test data responsive to the patient at a test time. The test data is available to a characterization processor at a result time. The characterization processor is also responsive to the continuous parameter so as to generate a medical characterization as a function of time. A characterization analyzer enables the characterization processor to update the medical characterization in view of the test data as of the test time.

Claims

1. A system configured to provide a caregiver an overall characterization of a health of a patient being monitored, the system determining relatively instantaneous measurement values of multiple physiological parameters over time and receiving indications of discrete medical-related events including timing of tests and timing and measurements of results, the system displaying said overall characterization of said health responsive to said measurements of said results, wherein the relatively instantaneous corresponds to measurements that are repeatedly determined from one or more sensors as compared to discrete results derived from medically-related test, the system comprising:

an electronic display;

a memory; and

a multi-parameter patient monitor comprising one or more hardware processors configured to interact with said memory and said electronic display to electronically;

receive from a discrete-time data source a first test time, said first test time being when a medically-related test was performed on said patient;

display a first visual marker juxtaposed with said timeline to visually indicate where in said timeline the calculation of said overall medical characterization timewise coincides with the first test time;

receive from said discrete-time data source a first result time and first result measurement values, said first result time being when results to said test were received;

display a second visual marker juxtaposed with said timeline to visually indicate where in said timeline the calculation of said overall medical characterization timewise coincides with the first result time, the second visual marker comprising a visual characteristic that associates the second visual marker with the first visual marker;

receive an update command;

recalculate said relatively instantaneous overall characterization of said health of said patient from the first test time, said recalculation responsive to said first result measurement values; and

alter the timeline of said overall medical characterizations to incorporate said recalculated relatively instantaneous overall characterizations.
