a patient breaths 100% oxygen while in a hyperbaric chamber
(pressure vessel) at a barometric pressure greater than sea
level. The dosage of oxygen is increased proportional to the
increase in chamber pressure; i.e. breathing 100% oxygen at 3
atmospheres absolute pressure is the equivalent of getting 300%
oxygen. The air we breathe each day has 21% oxygen. Most
chambers are capable of pressurizing to 1.5 to 3 times normal
atmospheric pressure. The hyperbaric physician determines what
pressure the chamber needs to go to for any given treatment. See
conditions we treat. There are two main types of hyperbaric
chamber. Monoplace: single patient, chamber pressurized with
100% oxygen, patient directly breaths the ambient chamber
oxygen. Some units offer intermittent air
