The actual number will vary on the clinical response given to the patient. Compression generally takes five to seven minutes. Patients are placed into a Hyperbaric Chamber. The chamber allows patients to sit or recline during treatments. Visual observation from inside and outside the unit is available through viewports or windows.
Communication is maintained to the chamber via an intercom link.
Patients are allowed to read books or magazines, relax, listen to music, or even sleep while being treated. Medical personnel may accompany patients during the treatment. Usually, four to 24 hours will be allowed between treatments. HBO therapy can be provided on an inpatient or outpatient basis depending on the clinical needs of the patient. Surgical dressings need not be removed for treatment to proceed.
