## Abstract

A patient support apparatus includes a control system operable to gather physiological information about a patient supported on the patient support apparatus. The information may be gathered from sensors, a user interface, or a hospital information system. The control system uses the data gathered to predict whether a patient is likely to be in need of care from a caregiver.

## Claims

### Claim 1

A method for predicting patient needs comprising:
detecting electromagnetic radiation from a field of view and providing a signal indicative of a characteristic of a patient in the field of view, the signal being based on the electromagnetic radiation; and
processing the signal to produce a value related to a stress condition experienced by the patient located in the field of view to determine whether a patient need is indicated by the value related to a stress condition experienced by the patient and to perform the predetermined action if the patient need is predicted.

### Claim 2

A method for predicting patient needs comprising:
detecting electromagnetic radiation from a field of view and providing a signal indicative of a characteristic of a patient in the field of view, the signal being based on the electromagnetic radiation;
detecting a status of equipment included in a patient support apparatus supporting the patient; and
processing the signal to produce a value related to a stress condition experienced by the patient located in the field of view to determine whether a patient need is indicated by the value related to a stress condition experienced by the patient and to perform a predetermined action if the patient need is predicted.

### Claim 3

A method for predicting patient needs comprising:
detecting electromagnetic radiation from a field of view and providing a patient signal indicative of a characteristic of a patient in the field of view, the signal being based on the electromagnetic radiation;
detecting a status of a component of the patient support apparatus; and
processing the signal to produce a value related to a stress condition experienced by the patient located in the field of view to determine whether the value has exceeded a predetermined limit and to perform a predetermined action if the value has exceeded the predetermined limit.
