Abstract

A medical pad has multiple layers. A first layer is for containing a first thermal-exchange fluid circulatable therethrough, with the medical pad being operable for thermal exchange between the first thermal-exchange fluid and a patient through a first side of the first layer. A second layer of the medical pad is interconnected to a second side of the first layer, opposite to the first side of the first layer. The second layer encloses a second thermal-exchange fluid that may have a freezing point of 0C or less. The medical pad is operable for thermal exchange between the second thermal exchange fluid and the patient.
