6. A system for monitoring a position and vital signs of a subject supported by a patient support apparatus, the system comprising:
a user device; and
a monitoring device comprising:
a first imaging component that obtains long wave infrared (LWIR) image data of the subject;
a second imaging component that obtains near infrared (NIR) image data of the subject and the patient support apparatus;
a processing device; and
a non-transitory, processor-readable storage medium comprising one or more programming instructions thereon that, when executed, cause the processing device to:
receive LWIR image data from the first imaging component and NIR image data from the second imaging component,
determine one or more boundaries of the patient support apparatus from the NIR image data,
construct one or more virtual boundaries that correspond to the one or more boundaries of the patient support apparatus,
determine a location of the subject with respect to the one or more virtual boundaries from at least one of the LWIR image data and the NIR image data,
determine a facial temperature of the subject from the LWIR image data,
determine a heart rate of the subject from the NIR image data,
determine a respiration rate of the subject from at least one of the LWIR image data and the NIR image data,
transmit the LWIR image data to the user device,
transmit the NIR image data to the user device, and
transmit a composite of the LWIR image data and the NIR image data to the user device,
wherein the user device is programmed to:
display the LWIR image data as a first image at a first display area on the user device;
display the NIR image data as a second image at a second display area on the user device; and
display a composite of the LWIR image data and the NIR image data as a third image at a third display area on the user device simultaneously with the first image and the second image.
