Each child will undergo the following screening exercise to determine the likelihood of being able to participate in the study: In order to assess ability to tolerate the placement of the oxygen hood in the hyperbaric setting, a hyperbaric oxygen hood will be placed upon the shoulders, or body of your child (depending upon size of your child) and with encouragement and comforting by you and study nurse, the child will be asked to maintain the placement of the hood for 15 minutes. Each child will be asked to blow through a straw, blow the nose, drink through a straw, or to swallow on command. Exclusion Criteria: Any previous HBO treatments.
