Hyperbaric Oxygen Therapy

Hyperbaric oxygen therapy - technical


Hyperbaric oxygen therapy (HBOT) is the use of oxygen at increased atmospheric pressure. The history of hyperbaric oxygen therapy can be traced back to the late seventeenth century, when Henshaw treated patients in a pressurized chamber. Initially, patients were treated with pressurized air. In 1955, the modern era of hyperbaric oxygen therapy was born.


Tracheostomy is an operation in which an opening is made in the trachea (windpipe) and a tube is inserted in order to maintain an effective airway. A tracheostomy is used for the emergency treatment of various airway problems involving the larynx (voicebox). A planned tracheostomy is most commonly performed on a person who has lost the ability to breathe naturally and is undergoing long-term ventilation or is unable to keep saliva and other secretions out of the trachea. Permanent tracheostomy is needed after laryngectomy (removal of the larynx).


Z-plasty is a surgical technique that is used in plastic surgery to change the direction of a preexisting scar in order for it to be hidden within the natural creases of the skin. Z-plasty is also used to relieve skin tension occurring as a result of contracture of a scar. The technique is especially useful for revising unsightly scars on the face and for releasing scarring across joints, such as on the fingers or in the armpits, that may restrict normal movement or cause deformity.
