1. A system configured to transfer heat to a patient, the system comprising:
a heating device, configured to transfer heat to the patient based on a body heat score that indicates whether the patient is likely to sweat, the heating device comprising:
a convective warming blanket;
a heater circuit coupled with the convective warming blanket and configured to produce heat, the heater circuit including a heating level setting, a temperature setting, a pause period setting, and a time setting;
a controller communicatively coupled to the heater circuit, the controller comprising a processor, comprising:
a sensing component configured to receive one or more physiological indicators of the patient, wherein the physiological indicators comprise an entered physiological indicator from an input component and a measured physiological indicator from one or more sensors;
a scoring component communicatively coupled to the sensing component and configured to:
determine a physiological score from the physiological indicators;
determine the body heat score from the one or more physiological scores;
determine whether the body heat score meets a score threshold indicating that the patient is likely to sweat; and
direct the heater circuit to produce a first amount of heat based on whether the body heat score meets the score threshold; and
a timing component communicatively coupled to the heater circuit and the sensing component and configured to:
determine a duration of heat transfer from the heating device to the patient, the duration beginning when the heat transfer begins and ending based on a time condition set by the time setting of the heater circuit, wherein the time condition is based on an estimate of an excessive amount of heat transferred to the patient; and
determine when the measured physiological indicator is received by the sensing component.
