To the Editor:—
Anesthetists who use Dr. Ralph Waters' closed soda lime absorption technic have been plagued by the tendency of most masks to leak between the rubber rim and the body as soon as slight stretching of the rubber has occurred. I have tried various things to achieve an air-tight joint, from sections of inner tubing to folded adhesive tape. The latter is the most successful but has obvious disadvantages. A device more sanitary and almost as effective is a couple of curved half inch strips of blotting paper slipped between the rubber rim and the celluloid or metal body, and moistened with water.
