Head Nurse, St. Elizabeth Dispensary of the Chicago Municipal Tuberculosis Sanitarium. In the treatment of tuberculosis, the best results have been obtained in sanatoria. In most cities, however, sanatorium treatment is not possible for many patients; consequently home treatment must be provided. This can be done most successfully when we imitate as far as possible the sanatorium method. This paper describes some of the arrangements for outdoor sleeping which may be provided for a patient taking the "cure" at home. The Fresh Air Room. Select the best lighted and best ventilated room, preferably one with southern exposure, for the patient to sleep in. All superfluous furniture and hangings should be removed. In doing this, however, the room need not be made cheerless; small rugs, washable curtains and one or two cheerful pictures may be allowed. There should be some means of securing cross ventilation in all sleeping rooms, as for the ideal fresh air room this is most essential. When this cannot be arranged and when there are windows only on one side of the room and a transom is lacking, the window should be open at both upper and lower sash. This arrangement allows the bad air to escape through the opening at the top, while the fresh air enters below. The "French window" which opens from floor to ceiling by swinging inward is to be recommended for the ideal sleeping room. In ventilating a room which is used for a sitting room in the daytime, especially in stormy weather, it is sometimes necessary to protect the patient from a direct draft. For this purpose a shield may be made from an ordinary piece of hardwood board, eight inches wide (or larger) and long enough to fit in between the side casings. It can be covered with wire netting, cheese cloth or muslin. There are a variety of wind shields on the market called sash ventilators, or air deflectors. Window Tents
