Fungal contamination of cervical sponges.

The advantages of this system are. (1) Should the patient in a capsule require attention during treatment he is accessible without undergoing complete decompression. (2) The treatment of one patient can be controlled without interrupting that of others. (3) A capsule can remain empty while the others are in use, so that scrupulous cleaning can be performed after use by an infected patient. (4) If suitably designed the patient can sit up, which is impossible in a conventional small chamber. With the equipment now available, however, I believe that several small chambers in a properly staffed unit is the most practical solution if hyperbaric oxygen is to be made available to those who require it.-I am, etc., D.
