The art of anaesthesia . is thenplaced in the mouth and pushed as far back as it will go(Fig. Ill), and the tongue is drawn forward and tied tothe tube (Fig. II). The tube pushes the soft palate up-ward and effectually closes the passageway through thenose (Fig. Ill) so that no air can escape through the nos-trils, while an opening in the bottom of the tube permitsthe air to pass freely down the throat. For supplying the air, a foot bellows is used (Fig. I).As the air is conducted through the tube it passes a valve(3) which regulates the inspiration and expiration. Withwatch in hand, or in synchronism with his own respiration,the attendant turns the ring that governs this valve alter-nately to the right and left at regular intervals. When the ring is turned to the right the air is forced intothe lungs, and when the ring is turned to the left the airis shut off. at the same time a small vent is opened and the 357 358 APPENDIX Artificial Respiration and Resuscitation~ Meltzer Method - GEO.

Just below this valve is onefor regulating the pressure of the air given the patient(). At the start the pressure used is very low, but is in-creased by gradual closing of the valve, until the chestshows a regular normal heaving. In case the apparatus is hurriedly called into use duringan abdominal operation, in which case the abdominal board(1) cannot be strapped on, a stomach tube is passedthrough the pharyngeal tube, through the oesophagus andinto the stomach (Fig. Ill). An important feature of the apparatus is that it canhe operated by one man, who need not be an expert. Thehellows is worked by the foot and the respiratory valve isoperated by the right hand, leaving the left hand free formaking any adjustments that may be necessary.
