Hyperbaric Oxygen Therapy Clinical FAQs

Q. What is Hyperbaric Oxygen Therapy?

A. Hyperbaric Oxygen Therapy (HBOT) is defined as breathing 100% oxygen while in an enclosed system pressurized to greater than one atmosphere (sea level). More Info

Q. How does HBOT enhance wound healing?

A. Hyperbaric oxygen therapy delivers oxygen quickly and in high concentrations to injured areas systemically. The increased pressure changes the normal cellular respiration process and causes oxygen to dissolve in the plasma. This results in a substantial increase in tissue oxygenation. HBOT is beneficial because it stimulates the growth of new blood vessels and increases oxygenation that can arrest certain types of infections and enhance wound healing. More Info

Q. What is the protocol for hyperbaric treatment?

A. The treatment protocol is established by the medical director of the hyperbaric program in consultation with the patient's referring physician. The patient remains under the care of their primary physician throughout the course of treatment. Acute conditions may require a treatment period of ten days or less, while chronic conditions may require therapy over a few months. Although treatment schedules will vary, most treatments will be administered during two hour sessions, once or twice a day, several times a week. HBOT therapy is generally administered on an outpatient basis. More Info

Q. How often is HBO administered?

A. Although treatment schedules will vary, most treatments will be administered  during two hour sessions, several times a week.  Acute conditions may require a treatment period of ten days or less, while chronic conditions may require therapy over a few weeks. More Info

Q. What does a patient experience during treatment?

A. The first stage of treatment is compression, in which the pressure inside the system is gradually increased.  The temperature will rise and later be adjusted to a comfortable level.  The patient  will feel a fullness in the ears.  Instruction is provided to help clear the pressure and relieve temporary discomfort.  Inside the chamber, the patient can sleep, watch TV, or a video tape, listen to music, read or just relax.

Q. Is HBO reimbursable?

A. Almost all health care plans/third party payors including Medicare reimburse for HBO treatments performed on currently accepted disorders by CMS. More Info


Hyperbaric Oxygen Therapy Technical FAQs

Q. What is the recommended service for our chamber?

A. Please refer to the chambers Operation and Maintenance manual for recommended daily, weekly, monthly, semiannual and annual servicing requirements.  Annual preventative maintenance is the most effective way to guarantee the proper function of your chamber and reduce the possibility of non-scheduled maintenance and down time later on. Perry Baromedical Corporation strongly recommends that all chambers be serviced annually by an approved Perry technician.

Q. What are acceptable cleaning and disinfecting agents for the Acrylic Tube?

A. The following are acceptable:

  • Detergent in a solution of warm water (not exceeding 120 degree F.). The acrylic cylinder should be washed with a clean, soft, lint-free cloth that has been moistened in a solution of water and mild soap, Joy (or) Ivory dish detergent (1:100 water solution).Rinse with a soft, lint-free cloth moistened with clean water.  Do not allow water or disinfectant liquid to accumulate inside the chamber.  Never use a dry cloth or abrasive cleaning agents on the acrylic window.
  • Commercial Products approved for cleaning and disinfecting are:
    • Tor HB
    • Coverage HB
    • Hibitane
    • Ascend
    • Asepti HB
  • Do not use any cleaners or disinfectants containing alcohol. They initiate crazing of the acrylic cylinder.

Please note that many other formulated hospital cleaners contain very high concentrations of Ethanol, Isopropanol or Benzyl Alcohols which may cause serious damage to the acrylic window. IF IN DOUBT PLEASE CONTACT YOUR CHAMBER SUPPLIER FOR ADVICE.

Warm soapy water or correctly diluted cleaners may be used at up to 100°F (38°C) MAXIMUM


Soft lint-free cloths must be used to prevent scratching the acrylic window.

Do not use cleaners when the chamber is pressurized.

Caution must be exercised when using cleaners containing strong perfumes
– some of which are known to damage acrylic.
