An IV infusion bag carrier pack is arranged as a substantially hollow, flexible bag having an interior that is divided into two interior compartments by a flexible, heat permeable divider panel, one interior compartment being arranged to receive and confine an IV fluids bag and the other interior compartment arranged to receive and confine the inflatable pressure cuff member of a blood pressure apparatus, whereby an IV fluids bag contained in the first pocket may be selectively pressurized by inflation of the blood pressure cuff contained in the second pocket whereby selectively controlled infusion delivery of IV fluids contained in the carrier pack apparatus may be continuously maintained irrespective of the relative disposition of the carrier pack apparatus and patient during treatment, extrication and rescue in the field, and transport to a medical facility.
