Abstract: Monitoring patient vital signs is performed by analyzing videos recorded of a patient. An algorithm is used to compute the real-time patient vital signs based on video images of the patient. These images can be captured by a video monitoring device positioned over a patient's bed. The video monitoring device can include a thermal camera and a near infrared camera that continuously send video images to a processing unit. The thermal image is used to locate the patient's face and chest. The images are analyzed with an algorithm employed to determine a patient's heart rate, respiration rate, temperature, and body position.

Abstract: A monitoring system that includes an infrared detector comprising a field of view that detects temperature data from the field of view and provides a signal indicative of at least a detected temperature of a subject. The system includes a tab comprising a tab temperature that is positioned within the field of view such that the infrared detector detects the tab and emits a signal indicative of a detected temperature of the tab. The system includes a temperature sensor secured to the tab that detects the tab temperature and provides a signal indicative of a reference temperature. A control unit is communicatively coupled to the infrared detector and the temperature sensor and computes a net value between the detected temperature of the subject and the detected temperature of the tab. The control unit calculates a core temperature of the subject by combining the net value with the reference temperature.

Abstract: A patient monitoring system comprises a contactless monitoring unit having a contactless patient monitor and operable to communicate with equipment in a patient room and components of hospital information system. The patient monitoring system implements methods for detecting and optimizing signals from a patient supported on a patient support apparatus. The patient monitoring unit includes a power source and a controller. The contactless patient monitor includes a first detector, an emitter, and a controller. The controller processes signals from the first detector and vary the operation of the emitter to change the environment in the field of the detector such that the signals detected by the first detector are optimized.
