ABSTRACT OF THE DISCLOSURE Apparatus is provided herein for inhalation rewarming for the treatment of victims of hypothermia. The apparatus includes a water reser- voir. A steam chamber communicates with ambient air. A heater means is associated with such water chamber, for the generation of steam into such steam chamber. An opening is provided admitting air to the steam chamber, thereby to provide an air-steam mixture. A first conductor is connected to the steam chamber for the conducting of the air-steam mixture from the steam chamber in a first direction. A valve is provided in the first con- ductor for varying the inflow of the ambient air while simultaneously re- ciprocally varying the inflow of the air-steam mixture and providing a sub- stantially constant volume flow into the first conduit means. The valve includes actuated operator means for initially introducing sufficient ambi- ent air into the air-steam mixture in the first conductor means to provide a continuous flow of the water-saturated air at the temperature of about 35°C- about 45°C. A flexible conduit leads from the valve means for con- ducting the water-saturated air in the first direction. Finally a breath- ing mask is connected to the flexible conduit means downstream of the valve means. The breathing mask includes one-way valves therein to permit the water-saturated air-to flow only in the first direction to the breathing mask, whereby the water-saturated air at the temperature of about 35°C- about 45°C is drawn into the breathing mask by the negative pressure pro- duced by human inhalation, and exhaled air produced by human inhalation is vented. Thus, a simple, effective apparatus for inhalation rewarming has been provided which has special relevance to first-aid treatment of accidental hypothermia.
