General HBOT Information

Hyperbaric oxygen therapy is when a patient is enclosed in a chamber and is given 100% oxygen to breathe while the air pressure inside is increased. This treatment helps the body’s natural healing mechanisms work more effectively.

HBOT works by increasing the availability of oxygen in your body and blood, which research has shown has many beneficial impacts. Read the How HBOT Works page to learn more.

Many illnesses and injuries linger because enough oxygen can’t reach the damaged area to support the healing process.

HBOT provides extra oxygen that dissolves into all the body’s fluids and tissues, which allows it to be carried to areas where circulation is diminished or blocked. This allows oxygen to reach damaged bone and tissue, which promotes the body’s own healing process.

HBOT has been proven to promote healing of chronic wounds and acute injuries, and studies are showing promising results with improved function following traumatic brain injury, and for neurological conditions such as Alzheimer’s. HBOT improves patient quality of life in many ways when standard medical treatment has not been successful.

Most patients are very comfortable and they either watch tv, listen to music/audiobook, or sleep.

Pressurization increases the temperature, so HBOT chambers are air conditioned for patient comfort.

Sometimes the pressure changes will make a patient’s ears feel full, like on an airplane. Some people find this uncomfortable. This will go away when the chamber decompresses at the end of the treatment session.

An HBOT session should be painless. If you experience any pain during an HBOT session, notify the hyperbaric technician.

HBOT involves being in a small, enclosed chamber for an extended period of time. For safety reasons decompression must be slow, so there is no rapid emergency exit if a patient is in distress.

Claustrophobia is a relative contraindication for HBOT. This means you need to discuss the issue with your doctor, and decide together whether it is the right choice for you.

The general recommendation is that claustrophobic patients who choose HBOT should take an anti-anxiety medication immediately prior to each treatment session.

Tobacco products interfere with the body’s ability to transport oxygen. Patients are strongly recommended to stop smoking, vaping and using any smokeless tobacco for the duration of the treatment plan.

An HBOT treatment session will be at a scheduled time. It varies based on patient needs, but an average session takes about 2 hours.

An HBOT treatment plan varies based on patient need and is determined by the hyperbaric doctor. The decision is based on the patient’s diagnosis and their body’s response to treatments.

On average, patients receive one treatment per day (Monday – Friday) for about 30 days.

Generally speaking, a patient with a chronic condition usually has a longer treatment plan than patients with acute conditions, such as an injury.

HBOT treatment is prescribed by a physician and performed under medical supervision. Although there is a minor risk of side effects as with any medical treatment, overall hyperbaric oxygen therapy is very safe.

The risks of properly administered HBOT are minimal. Most side effects are not commonly experienced, and many are very rare.

These mild, generally temporary side effects can occur:

  • Fatigue
  • Ear discomfort
  • Serous Otitis (fluid collects in ears)
  • Vision changes (blurring, change in prescription)
  • Maturing cataracts

HBOT treatments use proven safety methods, such as very slowly inducing pressure changes, to minimize risk and help prevent side effects.

HBOT Session Information

The HBOT treatment process is straightforward and will be the same for each treatment.

  • If wound care is required, hyperbaric clinic staff will perform dressing changes (this may be before or after treatment).
  • You will remove your clothing, put on a cotton gown and lie on a gurney, which will be wheeled into the chamber.
  • After the door closes, you will hear a gentle hissing sound as the chamber pressurizes.
  • As pressure increases, you may feel warmer. This is expected, and chambers are air conditioned.
  • As pressure increases, you will feel a sense of fullness in your ears. Begin ear clearing tactics, which you can stop when compression is complete.
  • You may rest, read, watch a show or listen to music during treatment.
  • During decompression, the temperature will cool and you will feel a slight popping in your ears.
  • Following treatment, clinic staff will update your doctor on your progress.

Patients are only allowed to wear clean cotton clothing. No cosmetics, perfume, hair products, deodorants, wigs or jewelry are allowed.

Inform the technician if you are taking any medications, including non-prescription drugs or supplements.

Do not drink alcohol or carbonated beverages for 4 hours prior to a treatment session.

It is important to notify the technician if the patient:

  • Has any cold or flu symptoms
  • Has sinus, nasal or chest congestion
  • Has a fever
  • May be pregnant
  • Has had a medication change
  • Is a diabetic who did not take their insulin prior to treatment
  • Is anxious or has any concerns

Yes. NexGen Hyperbaric clinics all employ monoplace chambers, which are designed for a single patient. Treatment is administered with the patient lying on a gurney that is rolled into the chamber.

Chambers are clear acrylic, and patients remain in full view of technicians, and have contact at all times with an intercom.

HBOT Administrative Information

Patients are accepted either by self-referral or by physician referral. Patients are evaluated by staff and treated based on their specific needs. To schedule an evaluation, contact us.

Referring physicians must order a chest x-ray prior before a patient can receive HBOT treatment. This is to make sure the patient does not have an untreated pneumothorax (collapsed lung), a condition that makes it unsafe to receive HBOT.

Yes. Your doctor refers you for HBOT treatment, and stays in charge of your care. The hyperbaric clinic’s doctor serves as a consultant, working closely with your doctor to plan and manage your HBOT treatment.

It depends on the condition being treated.

Most insurance companies will cover hyperbaric oxygen therapy treatment for conditions approved by the FDA. However, off-label treatments such as those in successful clinical trials are still in the process of obtaining approval, and are considered an off label application. Insurance will generally not cover these treatments.

Your clinic’s staff will assist with determining if insurance coverage is available before treatment begins.

Off-label treatment is when a doctor prescribes a medication or therapy for something other than what it is FDA approved for. This is routine throughout medicine, because it’s common for the medical community to recognize when a treatment has a clear benefit for something else when treating patients for an approved condition.

Off-label use often leads to clinical studies that result in the formerly off-label condition becoming approved as well. One of the most famous examples of this is minoxidil (Rogaine), which was originally approved as a blood pressure drug, but is now used primarily for treating hair loss.

It is a standard practice to prescribe off label treatments when research supports them, but the years of additional studies and paperwork to secure FDA approval is ongoing. This is what NexGen Hyperbaric offers – early access to a safe therapy showing positive results in medical studies for new uses.

Yes, NexGen has participated in clinical trials for HBOT treatment of conditions such as traumatic brain injury. Patients interested in whether this is an option for them may contact us, and it can be discussed on a case by case basis.

The Undersea Hyperbaric & Medical Society is a nonprofit organization that sets rigorous patient treatment and facility standards within the hyperbaric medicine specialty.

UHMS Accreditation means an HBOT clinic meets the highest standards of patient care and safety, which is determined through a comprehensive evaluation of each facility’s equipment, staff and training.

UHMS membership and accreditation is not a requirement. It is an elevated level of operational excellence NexGen Hyperbaric chooses to provide for our patients. All of our clinics are submitted for and receive UHMS Accreditation.
