Abstract: Systems for providing a transportable human heating system include a portable infrared (IR) field tent configured to provide IR heat therapy to a patient in the field. The tent includes a free-standing enclosure having a support structure providing sides and a base. The base defines an open bottom of the enclosure. A flexible surface supported by the support structure forms at least one side wall of the enclosure. At least one side wall of the enclosure includes an openable panel that provides access through the side wall into an interior of the enclosure. The tent includes an IR heating panel secured to an inner surface of the enclosure for heating a patient within the enclosure. A human heating system can optionally include a patient support apparatus, such as a stretcher. An IR field tent can be configured to attach to the apparatus, thus enclosing a patient upon the apparatus.
