1. A temperature measurement device, comprising:
a first sensing element, comprising a first type of temperature sensor, configured to sense an ambient temperature of an environment over a first time period;
a second sensing element, comprising a second type of temperature sensor different from the first type of temperature sensor, configured to sense a patient temperature of a patient over a second time period;
a controller in communication with the first sensing element and the second sensing element, the controller being configured to:
determine a first rate of change of the ambient temperature over the first time period;
determine a second rate of change of the patient temperature over the second time period, wherein the first time period and the second time period at least partially overlap;
determine a threshold rate of change;
select a first correction factor based at least in part on determining that the first rate of change exceeds the threshold rate of change;
determine a core temperature of the patient by applying the first correction factor to the second rate of change of the patient temperature in response to the first rate of change exceeding the threshold rate of change;
select a second correction factor based at least in part on determining that the first rate of change is less than the threshold rate of change; and
determine the core temperature of the patient by applying the second correction factor to the second rate of change of the patient temperature in response to the first rate of change being below the threshold rate of change.
