Oxygen delivery hoods consisting of a rigid transparent plastic shell that encloses the patient\'s head; they are typically mounted on a neck ring that provides a gas-tight seal. These hoods may include temperature, humidity, and oxygen concentration sensors; they may also include supply and exhaust ports for gas tube connections; some hoods also have ports for gas concentration analysis and to permit the patient to hear. The hoods are connected to the oxygen source using tubes or hoses. Adult oxygen supply hoods are frequently used for administration of high-pressure oxygen to patients who are inside hyperbaric chambers.
