The invention relates to a rescue stretcher for rescuing persons with an substantially rectangular, support litter which is configured to be rolled up and/or folded together and is made of a flexible, tear-resistant, water-proof sheet material, and with at least two fixed carrying loops on each longitudinal side of the rectangular support litter, wherein on the inner receiving surface of the support litter a cold protection unit consisting of a blanket-like heat maintaining element and, replaceably provided thereon a substrate configured to absorb bodily fluids, is detachable fastened and which when the support litter is being carried by the carrying loops forms an envelope-like, cold-insulated bedding for the person to be carried.
