Claims20
A patient support system comprising
- a patient support apparatus,
- a camera, and
- a controller coupled to the patient support apparatus and to the camera, the controller configured to receive image data from the camera and to determine at least one of pulmonary and circulatory characteristics of a patient supported on the patient support apparatus.
The patient support surface of 2, wherein the controller is configured to determine actual blood pressure based on the relative blood pressure value.
A method of determining a circulatory patient characteristic corresponding to a patient supported on a patient support apparatus comprising
- receiving image data from a camera,
- determining blood volume pulse information based on the image data, and
- determining a relative blood pressure value based on the blood volume pulse information corresponding to the patient face and to the patient extremity.
