1. A method comprising:
- engaging a heat exchange element with a patient, the heat exchange element being coupled to a controller for establishing patient temperature;
engaging a temperature sensing assembly with the patient, the temperature sensing assembly including a temperature sensor generating a signal representative of patient temperature, the temperature sensing assembly including a wireless transmitter wirelessly transmitting a signal representative of patient temperature to the controller, the controller including a wireless receiver receiving the signal from the transmitter, the controller controlling at least the temperature of fluid flowing through the heat exchange element at least partially based on the signal from the temperature sensing assembly.
