1. A wearable heating sleeve comprising:
a first sleeve portion configured to be secured to a popliteal fossa of a patient's leg;
a first heating pad coupled to the first sleeve portion;
a second sleeve portion configured to be secured to a foot of the patient's leg;
a second heating pad coupled to the second sleeve portion;
one or more temperature sensors associated with at least one of the first sleeve portion or the second sleeve portion;
a third sleeve portion configured to be secured to a calf of the patient's leg;
one or more compression bladders associated with the third sleeve portion; and
control circuitry electrically coupled to the first heating pad, the second heating pad, and the one or more temperature sensors, the control circuitry configured to:
determine a first risk weight based on a surgery classification of a surgical operation associated with the patient;
determine a second risk weight based on an anesthesia condition of the patient;
receive one or more temperature signals from the one or more temperature sensors;
determine an estimated core temperature of the patient based on the one or more temperature signals;
determine a third risk weight based on the estimated core temperature;
determine a risk value associated with the patient based at least in part on a weighted, normalized summation of the first risk weight, the second risk weight, and the third risk weight; and
at least partly in response to the risk value, activate the first heating pad, the second heating pad, and the one or more compression bladders.
