The quantity for a full-sized bath is usually 30 gallons. The temperature at which the medicinal baths are given is from 35° to 40° unless otherwise stated. For a cold bath (Balneum Frigidum) the patient is placed in water at 35° and the temperature of the water is lowered to 15° by the addition of ice. A tepid bath (Balneum Tepidum) is given at from 30° to 35°; a hot bath (Balneum Calidum) at from 37° to 43°. Effervescing baths are given at a slightly lower temperature than ordinary baths, the effervescence giving to the patient an increased sense of warmth.
