Abstract
In a patient monitoring system (10), shorter interval physiological parameters and longer interval clinical data are collected from a monitored patient (12). A composite acuity score generator (70) generates or updates a composite acuity score indicative of wellbeing of the patient (12) based at least on the sensed physiological parameters and the longer interval data. A monitor (22, 56) displays current values of at least one of selected sensed physiological parameters, longer interval data, and the composite acuity score.
Claims32
A patient monitoring system comprising:
- at least one sensor which senses physiological parameters of a monitored patient in real time;
- at least one database which stores interval data of the monitored patient collected at temporally spaced intervals;
- a processor programmed to:
- continually receive the currently sensed physiological parameters of monitored patient from the at least one sensor,
- retrieve the stored interval data from the database,
- continually calculate a real time acuity score in real time indicative of at least one of current wellbeing, a current risk of mortality, a current likelihood of single or multi-organ failure, and a current physical instability of the patient based at least on a composite of the sensed physiological parameters and the interval data such that the current acuity score changes as the sensed physiological parameters change;
- compare the real time acuity score with a threshold;
- and
- determine at least one of (1) the sensed current physiological parameters primarily responsible for the acuity score reaching the threshold and (2) the sensed current physiological parameters that are significant to medical personnel deciding a course of action for altering and enhancing the patient's current physiological condition;
- and
- a monitor which concurrently displays in real time the current values of (1) at least a selected one of the physiological parameters values sensed in real time, and (2) at least a selected one of the interval data, and (3) the calculated real time acuity score, and (4) the determined significant sensed current physiological parameters.
