1. A patient warming system, comprising:
a control unit comprising:
an I/O interface comprising two or more connectors, the two or more connectors having a same configuration;
a controller configured to execute a program stored in a memory of the control unit that identifies a warming device plugged into one of the two or more connectors and that controls application of power to the warming device relative to a set temperature and in accordance with the identity of the warming device;
warming devices interchangeably coupled to the control unit via the I/O interface, each warming device comprising:
one or more heating elements;
one or more temperature sensors; and
a connector that is configured to be coupled to any one of the two or more connectors,
wherein the program as executed by the controller:
monitors a rolling average of temperature measurements from the one or more temperature sensors when the set temperature is changed to a temperature lower than a current measured temperature; and
issues an over-temperature alarm or warning if the rolling average decreases by less than a predetermined amount over a predetermined time period.
