HBOT - Hyperbaric Oxygen Therapy: Treatment Costs, Benefits and Side Effects
Hyperbaric oxygen therapy, or HBOT, involves breathing oxygen inside a pressurized chamber. The recognized clinical standard defines it as at least 2.0 atmospheres of pressure using medical grade oxygen above 99% purity. At that level it is used in hospitals for conditions such as carbon monoxide poisoning, decompression sickness, gas gangrene and non-healing diabetic wounds. Portable soft-sided chambers operate at lower pressure, usually around 1.3 atmospheres, using room air with supplemental oxygen. These are used for recovery and general wellness rather than the emergency conditions above. Session costs range from under $100 at wellness clinics to more than $1,500 at hospital facilities. Common side effects include ear pressure and temporary vision changes.
What Is Hyperbaric Oxygen Therapy?
Hyperbaric oxygen therapy delivers oxygen under pressure, which lets your blood carry more of it than breathing at sea level allows. That extra oxygen is what drives the effects on healing, inflammation and energy. What HBOT actually involves depends on the type of chamber, and that difference matters more than most websites explain.
How Pressurized Oxygen Works in the Body
Oxygen normally travels bound to red blood cells. Under pressure it also dissolves directly into your blood plasma, lymph and cerebrospinal fluid. That dissolved oxygen can reach tissue where circulation is poor or blocked. The pathway looks like this: higher pressure → more dissolved oxygen → delivery into low-oxygen tissue → support for your own repair processes.
Hard-Shell vs. Portable Hyperbaric Chambers
Not every hyperbaric chamber does the same job. The Undersea and Hyperbaric Medical Society defines the therapy as at least 2.0 atmospheres absolute using medical grade oxygen above 99% purity. Hospital hard-shell chambers meet that standard. Portable chambers, also called mild or soft-sided chambers, run at lower pressure using room air with supplemental oxygen. Both have a place. They are not interchangeable, and the next section explains which one you will find at Renew.
Andrea Dean, CRNP, on how hyperbaric oxygen therapy fits into care for long-standing chronic symptoms.
The Hyperbaric Chamber at Renew: What It Is and What It Treats
Renew uses a portable soft-sided hyperbaric chamber, the Vitaeris 320, which runs at roughly 1.3 atmospheres using room air with supplemental oxygen. It is not a hospital hard-shell chamber, and knowing the difference before you book matters. Here is what each type is used for.
What a Portable Hyperbaric Chamber Supports
- Recovery after training, injury or surgery
- Energy, sleep quality and mental clarity
- Inflammation support as part of a wider functional medicine plan
- Adjunct support alongside IV nutrient therapy, peptide therapy and NAD infusion
- Sessions run about 60 minutes at low pressure and most people find them comfortable
This is the category Renew works in, and it is where a mild hyperbaric chamber is a reasonable tool.
What Requires a Hospital Hard-Shell Chamber
- Carbon monoxide poisoning
- Decompression sickness
- Gas gangrene and necrotizing soft tissue infections
- Non-healing diabetic wounds and delayed radiation injury
- Sudden vision or hearing loss and compromised skin grafts
These call for medical grade oxygen at 2.0 atmospheres or higher under hospital supervision. A portable chamber cannot deliver that, and Andrea will tell you so and help you find a hyperbaric unit that can.
If your goal is recovery, energy and inflammation support, a portable chamber is a sensible fit. If you have one of the conditions on the right, you need a hospital program instead. The next section covers what hyperbaric oxygen therapy is formally approved to treat.
This video shows a hospital-grade hard-shell chamber, the type used for the conditions listed above. Renew’s chamber is a portable soft-sided unit.
Hyperbaric chambers vary widely, and the video above shows a hospital-grade hard-shell unit rather than the portable chamber used at Renew.
What Hyperbaric Oxygen Therapy Is Approved to Treat
Hyperbaric oxygen therapy has a formal, and fairly short, list of recognized uses. Knowing that list helps you judge any clinic’s claims, including ours.
Conditions Requiring Hospital-Based Treatment
The Undersea and Hyperbaric Medical Society recognizes roughly 15 indications, and the FDA has cleared hyperbaric devices for a similar set. They include air or gas embolism, carbon monoxide poisoning, gas gangrene, crush injury, decompression sickness, severe anemia, intracranial abscess, necrotizing soft tissue infections, refractory osteomyelitis, delayed radiation injury, compromised grafts and flaps, acute thermal burns, non-healing diabetic wounds, central retinal artery occlusion and sudden sensorineural hearing loss. Every one of these assumes hospital protocols at 2.0 atmospheres or higher.
Conditions Currently Being Studied
Research continues in areas that are not approved indications, including traumatic brain injury, stroke recovery, fibromyalgia, long COVID and post-surgical healing. Early trials are encouraging in some of these areas and thin in others. Anything outside the recognized list is off-label, whichever chamber is used, and should be presented that way.
Off-Label and Wellness Uses of Hyperbaric Oxygen Therapy
Most people who come to Renew for hyperbaric sessions are not treating an approved indication. They are looking for support with symptoms that have not responded to standard care. These uses are off-label, meaning the evidence is still developing and no regulator has cleared them. Patients most often ask about hyperbaric support for:
- Fibromyalgia and chronic fatigue
- Lyme disease and environmental illness
- Neuropathy
- Traumatic brain injury and post-concussion symptoms
- Inflammatory bowel conditions
- Post-surgical and athletic recovery
Andrea reviews whether hyperbaric sessions make sense for you, and whether something else in your plan should come first.
Hyperbaric Treatment Cost
Hyperbaric treatment cost varies more than almost any other therapy, mostly because the chamber type and setting differ so much. Here is what to expect nationally and what you pay here.
How Much Does HBOT Cost at Renew?
A hyperbaric session at Renew Integrative Health costs $99. That is the full price of a single session, with no facility fee added. Most people do a series of sessions rather than one, and Andrea will talk through how many makes sense for your situation at your consultation.
Typical Hyperbaric Treatment Costs Nationally
The cost of HBOT elsewhere depends heavily on where you go. Hospital-based hyperbaric programs often exceed $1,500 per session, because they run medical grade oxygen at high pressure with clinical staffing. Standalone and wellness clinics generally charge between $100 and $500 per session. These national figures are for comparison and are not what Renew charges.
What Affects the Cost of HBOT
Several things drive the price difference between one hyperbaric provider and another. Chamber type is the biggest factor, since hard-shell systems cost far more to buy, install and staff than portable chambers. Facility setting matters too, as hospital hyperbaric programs carry clinical overhead that a wellness clinic does not. Session length, whether a physician is required on site, and local market rates all move the number. Because most protocols involve a series rather than a single visit, the per-session price is worth comparing carefully before you commit.
Insurance Coverage for HBOT Therapy
Renew does not bill insurance directly for hyperbaric sessions. You are welcome to submit a claim yourself, and we will provide receipts and documentation to support it. Whether a claim is paid is between you and your insurer, and we cannot promise an outcome.
It is worth knowing that insurers generally reimburse hyperbaric oxygen therapy only for the recognized indications listed above, delivered under hospital protocols. Sessions in a portable chamber for wellness or off-label purposes are usually paid out of pocket.
The Benefits of Hyperbaric Oxygen Therapy
Patients come back for hyperbaric sessions because of how they feel afterwards, and the reported benefits are consistent.
- Improved energy and mental clarity
- Reduced pain and swelling
- Support for collagen production and tissue repair
- Better sleep in the nights following a session
- Support for the body’s own recovery processes after exertion or injury
Individual responses vary, and results depend on your underlying situation and how many sessions you complete.
What to Expect During a Hyperbaric Oxygen Therapy Session
Nothing about a session is difficult, and most people find it restful. During pressurization your ears may need to pop, much like on an airplane, and you will be shown how to clear them. That phase takes about 5 to 10 minutes. For the next 60 minutes you can read, watch something or sleep.
As the chamber depressurizes you may hear crackling in your ears. Afterwards some people notice less pain and better sleep that night. Side effects are usually limited to ear pressure and temporary vision changes. Because oxygen raises fire risk, the FDA asks providers to follow strict safe-use instructions, and we do.
How to Prepare for Your First Visit
Preparation is mostly paperwork, and it makes the first consultation far more useful. Complete your medical history, diet log and current symptoms through the patient portal before you arrive. Include the last two years of testing, including labs and any imaging. Your first visit covers your history, a physical examination and an honest conversation about whether hyperbaric oxygen therapy is appropriate for you.
Common Hyperbaric Oxygen Therapy Myths
Myth: All Hyperbaric Chambers Are the Same
They are not. A hospital hard-shell chamber runs medical grade oxygen at 2.0 atmospheres or higher, while a portable soft-sided chamber runs closer to 1.3 atmospheres on room air.
Myth: FDA-Approved for a Condition Means Any Chamber Can Treat It
FDA clearance attaches to a specific device and a specific use, not to hyperbaric therapy as a general idea. A chamber cleared for one purpose is not automatically appropriate for the whole approved list.
Myth: Insurance Automatically Covers Hyperbaric Oxygen Therapy
Coverage is limited to recognized indications delivered under hospital protocols, and even then usually needs prior authorization. Wellness and off-label sessions are typically self-pay.
Frequently Asked Questions About Hyperbaric Oxygen Therapy
What Is HBOT Used For?
In hospitals, hyperbaric oxygen therapy treats a recognized list of conditions including carbon monoxide poisoning, decompression sickness and non-healing wounds. In wellness and functional medicine settings, portable chambers are used off-label for recovery, energy and inflammation support.
How Much Does Hyperbaric Oxygen Therapy Cost?
A session at Renew costs $99. Nationally, hospital programs often exceed $1,500 per session and standalone clinics usually charge between $100 and $500.
How Does Hyperbaric Oxygen Therapy Work?
Pressure allows oxygen to dissolve directly into your plasma and other body fluids, not just your red blood cells. That dissolved oxygen can reach tissue with limited blood flow.
Is a Portable Hyperbaric Chamber the Same as a Hospital Chamber?
No. Portable chambers operate at lower pressure with room air and supplemental oxygen, while hospital chambers deliver medical grade oxygen at 2.0 atmospheres or higher. They suit different purposes and are not interchangeable.
What Are the Side Effects of Hyperbaric Oxygen Therapy?
The most common are ear pressure during pressurization and temporary changes in vision. Serious effects are uncommon at the pressures used in a portable chamber.
Does Insurance Cover Hyperbaric Oxygen Therapy at Renew?
Renew does not bill insurance directly. You can file a claim yourself and we will provide receipts and documentation, though reimbursement for wellness sessions is unlikely.
What Conditions Can a Portable Hyperbaric Chamber Support?
It is used off-label for recovery, fatigue, inflammation and symptoms tied to chronic conditions. It is not a substitute for hospital hyperbaric care in an emergency.
