A system and method for warming a fluid for intravenous administration is presented. The system includes an enclosure, a frangible bladder disposed at least partially within the enclosure, and a first reactant of an exothermic reaction disposed within the frangible bladder. The apparatus includes a second reactant of the exothermic reaction disposed within the enclosure and external to the frangible bladder, and a channel at least partially enclosed by the enclosure. The frangible bladder is configured to be ruptured to mix at least a portion of the first reactant and the second reactant to initiate the exothermic reaction, thereby warming at least a portion of the channel.
