Besides drugs, various remedial measures are adopted in the treatment of failing circulation, such as rest in bed, light, non-fermenting diet with restriction of liquids, the cold bath, the Nauheim bath, cold air, regulated exercises, etc.

The Nauheim bath is a saline bath in the water of which carbon dioxide is set free. It tends to raise the arterial pressure, in some cases to a dangerous degree.

The drugs of the class are: Digitalis and its allies (strophanthus, convallaria, etc.), epinephrine, ammonia, and possibly camphor. There are a few others, such as caffeine, whose dominant actions place them more properly in other groups.
