The cuff is then turned downand fastened around the neck; it now becomes self-retaining. If thepatient is a vigorous alcoholic or a nervous individual, the bag shouldbe partly filled with nitrous oxid alone. When the gas is turned on,from two to six breaths, according to the patient, should be allowedthrough valves; the sliding cuff is then pulled out, and rebreathinginstituted, the expiratory valve being left very slightly open, say one-sixteenth of an inch. As signs of anesthesia appear, oxygen should beallowed to bubble through in about the proportion that will be main-tained throughout the operation. For the first five minutes the bagshould be slightly overdistended, thus insuring a deeper that, seven-eighths distention will meet all conditions. It isunnecessary to manipulate the valves after the patient has been ane
