Abstract

A method of monitoring patient data generates an optimal overview. The patient data is sensed by appropriate sensors and displayed as parameter values assigned to individual organ systems. A data field contains a plurality of parameter values and overview graphic images referring to organ systems are formed from this data field with the aid of a network switch and are displayed in response to a retrieval command.

Claims

1. A method in a computer for monitoring data of a patient and processing said patient data is display processors for selectively displaying said patient data, the method comprising the steps of:

storing a multiplicity of switching combinations in a storage field;

sensing data corresponding to vital signals of the patient with a plurality of sensors;

storing the data in trend memories connected to respective ones of the sensors of collecting a plurality of sets of data with each one of the sets of data relating to one of the vital signs;

selecting a specific one of the switching combinations with an image selection switch connected to the storage field and placing the selected switching combination in an active memory;

configuring a switching matrix, connected to said active memory and to said trend memories, in response to said selected switching combination to select particular ones of said sets of data for a particular organ or organ system;

processing the particular ones of said sets of data for said particular organ or organ system in said display processors, which are connected to said switching matrix, for display with respect to said particular organ or organ system and providing an output indicative of a desired display format for said particular organ or organ system; and

selectively connecting the display processors to at least one of a plurality of display fields with a coordinating switch for displaying said display format.

2. The method of claim 1, further comprising the step of selecting said display format to represent said particular ones of said sets of data in the form of a curve plotted as a function of time.

3. The method of claim 1, further comprising the step of selecting said display format to represent trends of the particular ones of said sets of data as functions of time.

4. The method of claim 1, wherein said organ or organ system includes the following:

consciousness/central nervous system (CNS), respiratory system, cardiovascular system and metabolic system.

5. The method for claim 1, wherein the display of the display format provides an indication of the status of the patient.

6. The method of claim 1, wherein the display of the display format for said particular organ or organ system provides an actual condition at a point in time.

7. The method of claim 6, wherein the display of the display format further provides an overview of the particular ones of said sets of data for said particular organ or organ system over a previously determined time duration.

8. A circuit arrangement for monitoring data of the patient which are assigned as parameter values to respective individual organs and organ systems, the circuit arrangement comprising:

a plurality of sensors for sensing corresponding ones of a plurality of vital signs of the patient indicative of body functions;

a plurality of trend memories connected to corresponding ones of said sensors for collecting a plurality of sets of data with each one of said sets of data relating to one of said vital signs;

matrix switching means connected to said trend memories for selecting particular ones of said sets of data for a particular organ or organ system for processing;

display processor means connected to said matrix switching means for processing the particular ones of said sets of data for said particular organ or organ system for display with respect to said particular organ or organ system and to provide an output indicative of a desired display format for said particular organ or organ system;

display field means for displaying said display format;

coordinating switch means for connecting said display processor means to said display field means;

storage field for storing a multiplicity of switching combination for selecting said particular ones of said sets of data;

image selection switch means connected to said storage field for selection a specific one of said combinations;

an active memory for receiving the specific one of said combinations; and

,

said active memory being connected to said matrix switching means for configuring said matrix switching means with respect of the selection of said sets of data and to said coordinating switching means for selectively connecting said display processor means to said display field means.

9. The circuit arrangement of claim 8, said display processor means including first and second sets of display processors connected to said matrix switching means;

said display field means including first and second sets of display fields; and

, said coordinating switch means including a first set of coordinating switches for interconnecting said first set of display processors and said first set of said display fields, and a second set of coordinating switches interconnecting said second set of display processors and said second set of display fields.

10. The circuit arrangement of claim 8, further comprising:

a computer connected to said storage field for changing said multiplicity of switching combinations;

a key pad connected to said computer for issuing commands to said computer for selecting a particular switching combination from said multiplicity of switching combinations stored in said storage field.
