It is our purpose in this report to describe a modification of the oxygen tent principle which will obviate many of the disadvantages of the large oxygen tent, namely low maximum oxygen concentrations, inaccessibility of the patient, difficulty of application, and psychic phenomena such as claustrophobia and feeling of suffocation. Much remains to be done before the physiologic aspects of oxygen therapy are completely established. Meanwhile, progress in therapy with oxygen is hindered by the too complete reliance by the clinician on equipment whose chief merit is long usage.
It appears that a small hood or helmet enclosing the head alone might overcome several of the disadvantages inherent in the large oxygen tent. The principle of such a hood is not new. Similar means have been used previously for oxygen administration.1 However, a review of the available literature revealed nothing to compare closely with the equipment to be described.
