Abstract
A heat flux sensor is used in conjunction with a patient sensor, such as a patient temperature sensor, and which is secured to the patient in close proximity to the patient sensor. The heat flux sensor monitors the heat flux between the patient and the environment. Upon dislodgement of the patient probe, the heat flux sensor senses a change in heat flux that is of a predetermined amount and provides a signal indicating that the patient probe has become partially or fully dislodged from the patient. In the case of a patient heat sensor, the use of a heat flux sensor provides a quicker and larger signal than would be seen by merely monitoring the change in temperature due to partial or full probe dislodgement.
