Frequently Asked Questions

What is Hyperbaric Oxygen Therapy?

Hyperbaric Oxygen Therapy is the use of prescribed high pressure oxygen to treat a variety of health conditions and diseases. Breathing pure oxygen under pressures greater than sea level increases the amount of oxygen carried by the blood, enabling the oxygen to be dissolved into the hard-to-reach plasma, lymph, and cerebrospinal fluids surrounding the brain and spinal cord. These fluids more easily carry the increased oxygen to affected and damaged areas at up to 1,200% the normal concentration, thus providing a greater opportunity for healing.

Is Hyperbaric Oxygen Therapy right for you?

Hyperbaric Oxygen Therapy is an effective treatment for a variety of medical conditions either as a primary or adjunctive treatment. It is non-invasive with very few (and rare) potential side effects and has very few contraindications. The medical staff at HMS evaluates each patient to determine whether Hyperbaric Oxygen Therapy is appropriate. If the medical staff determines that Hyperbaric Oxygen Therapy is appropriate, they will customize a patient’s individual treatment protocol.

What Medical Conditions are treated at HMS?

HMS is a full service free-standing provider of Hyperbaric Oxygen Therapy, able to care for patients with a wide range of medical conditions. The FDA currently recognizes Hyperbaric Oxygen Therapy for 14 medical conditions, all of which are generally covered by insurance. In addition, there are many other medical conditions that research has demonstrated efficacy. HMS serves both groups as long as the condition is supported by existing research or is consistent with the mechanisms of action of HBOT.

What does Hyperbaric Oxygen Therapy feel like?

At the start of the treatment session, oxygen immediately begins to circulate and the pressure gradually increase. The patient will generally start to feel a fullness sensation in the ears, similar to ascending or descending in an airplane. This fullness should only last about 10-15 minutes and an experienced HMS hyperbaric technician will guide the patient to relieve any ear pressure. Once treatment pressure is reached, patients relax and just breathe normally. Near the end of the treatment session, the hyperbaric technician will gradually decrease the pressure in the chamber, a process that lasts about 10 minutes. During this decompression stage, it is common for patients to experience a slight popping sensation in the ears as a result of the change in pressure.

Are there any side effects associated with Hyperbaric Oxygen Therapy?

HBOT is an all natural therapy with generally no, or temporary, side effects. However, mild irritation to the ear drum may occur in about 10% of patients. The technicians at HMS will be with you every step of the way to prevent this from occurring. Other side effects may include temporary vision changes, dizziness or lightheadedness. In very rare instances, oxygen toxicity may occur, however, risk of this is mitigated by our HBOT protocols and comprehensive patient screening process.

Is there any preparation required for Hyperbaric Oxygen Therapy?

We recommend that patients avoid eating or drinking (specifically carbonated beverages) directly prior to treatment, unless medically required, to avoid the need to use the restroom or cause an upset stomach during the session. Some medications are incompatible with Hyperbaric Oxygen Therapy; a complete list of medications and supplements taken by the patient should be provided to the medical team during the initial consult, and updates should always be provided. To maximize the benefit of Hyperbaric Oxygen Therapy, smoking of any kind should be avoided during the course of a patient’s complete treatment protocol. Smoking causes vasoconstriction and accumulation of carbon monoxide and other wastes, all which are counterproductive to Hyperbaric Oxygen Therapy. Lastly, alcohol consumption should be avoided at least 8 hours prior to treatment.

What is allowed and not allowed inside a hyperbaric chamber?

At your consultation, the complete process and list of items that are allowed and not allowed will be reviewed. Each patient is provided 100% cotton scrubs, sheets, and blankets as well as a plastic cup with water, if desired. Most other items are not allowed into a hyperbaric chamber with 100% oxygen. Prior to entering the chamber, an HMS technician must inspect and approve all items and garments. Examples of items prohibited inside the hyperbaric chamber include deodorant, lotion, perfume, mousse, gel, hairspray, makeup, jewelry, hair accessories, hearing aids, hard contact lenses, dentures, prostheses, nail polish (unless applied at least 48 hours prior to treatment), IV medication, and any clothing item that has buttons, snaps, Velcro, iron-on decals, or under-wiring. The HMS technicians will make sure that these policies are followed for every treatment session.

What do I do inside the hyperbaric chamber?

Many patients sleep, watch TV, or a movie. For your enjoyment, each hyperbaric chamber at HMS is paired with its own TV and DVD player. Patients are welcomed to watch their favorite TV programs, select a DVD to watch from our library, or bring DVDs of their own to watch.

How many treatments will I need?

Every HMS patient is unique and evaluated according to their condition and their response to therapy, which determines the number of treatments needed. Generally, patients require 30-40 sessions, though this could be more or less depending on the patient’s specific condition or circumstance. Hyperbaric Oxygen Therapy works cumulatively in the body and the greatest benefit is seen when treatments are regular (like going to the gym). Therefore, treatment sessions are typically scheduled 4-5 days a week.

Is there any reason that Hyperbaric Oxygen Therapy is not recommended?

There are a few contraindications to Hyperbaric Oxygen Therapy such as if you have an untreated pneumothorax, moderate to severe COPD, bullous lung disease, or are currently receiving certain chemotherapeutic agents. During the consultation with a member of our Medical Team, each patient is evaluated to determine whether Hyperbaric Oxygen Therapy is a safe and appropriate course of treatment.

Is Hyperbaric Oxygen Therapy covered by insurance?

Hyperbaric Oxygen Therapy is generally covered by insurance for the 14 FDA approved medical conditions. Insurance generally does not cover off label conditions. In either case, insurance will most likely cover the consultation visit, regardless of condition. Please note that at HMS we offer payment plans and financial assistance programs where treatment of a condition is not covered by insurance.
Our policy is to do our best to accommodate all candidates for Hyperbaric Oxygen Therapy.

How does HMS monitor and/or evaluate the Hyperbaric Oxygen Therapy treatments I receive?

At the initial consultation, each patient’s condition is evaluated to determine that Hyperbaric Oxygen Therapy is appropriate and a baseline marker is set. Then, during each HBOT visit, patients are monitored by a trained Hyperbaric Technician and a member of the Medical Team (link to medical team page). Every visit is documented with a specialized electronic medical records system to help track each patient’s progress. Additionally, formal evaluations are performed following the completion of every ten treatment sessions and upon completion of the treatment protocol.

What kind of hyperbaric chambers does HMS use?

Each of our facilities uses state-of-the-art monoplace hyperbaric chambers. These chambers are made of metal and acrylic which differ from the soft or mild variety in that they deliver 100% oxygen vs. room air (which is only about 20% oxygen), and are able to reach greater atmospheric pressure levels. This allows for the treatment of a wider variety of health conditions more efficiently and effectively.

What is the difference between On and Off Label?

On-Label Conditions are conditions that have been approved by the Food and Drug Administration for hyperbaric treatment and are generally covered by insurance.

Off-Label Conditions are conditions that have not yet been approved by the FDA for hyperbaric treatment. In general, off label conditions are not covered by insurance.

For more information about on and off label designations, please visit the FDA’s website at www.fda.org.

Is there research on the use of HBOT for Off Label conditions?

Yes, many conditions have very promising research to support the use of HBOT. We are continually compiling a library of research on many of these conditions, which can be found on our Conditions page.

How many indications are on label in the US vs. other countries?

In the U.S., there are 14 FDA approved conditions. In Europe, however, there are over 40 approved indications. In Japan and China, there are over 60.

Why does HMS treat certain Off Label conditions?

The benefits of HBOT for certain conditions considered Off Label are well documented in supporting research and through the experience of patients around the world and at HMS. Core to our mission is to help and provide access to all patients who may benefit from HBOT. We believe HBOT can enhance the quality of life and well-being of patients that have many conditions that are considered Off Label.

What determines whether HMS will treat an Off Label condition?

There is extensive research available for many Off Label conditions that support its use. Through this research and our experience with the science of HBOT, also referred to as the mechanisms of action, we are able to apply this understanding to the underlying factors of various conditions and evaluate if HBOT is appropriate for a patient’s condition.

Do Off Label conditions ever become On Label?

Yes. Research is ongoing and there are movements underway to approve traumatic brain injury (TBI) and post concussion syndrome, in particular. However, the FDA approval process and requirements are quite extensive. While the therapeutic benefits of HBOT have been understood for decades, if not centuries, many of the conditions that are considered On Label, such as Diabetic Foot Ulcers and Non-Healing Wounds, were only approved relatively recently. As the FDA approval process can take quite some time, because a condition is currently considered Off Label, that is not necessarily a reflection on the effectiveness of HBOT for that condition.
