NHMI’s 60-session study is a physician-designed, near-daily hyperbaric protocol in hard-shell chambers using 100% medical-grade oxygen—built for patients who want measurable neurological and systemic change, not spa-style “wellness” dives.
Limited enrollment. Typical commitment is five treatment days per week over approximately twelve weeks.
"At the National Hyperbaric Medicine Institute, we treat the 60-session protocol as a high-level medical study—not a casual drop-in service."
The study is structured around near-daily exposure to 100% medical-grade oxygen in hard-shell chambers, five days per week, over approximately twelve weeks. This cadence is designed to support angiogenesis, epigenetic signaling, and tissue remodeling that simply do not emerge with occasional, one-off “drop-in” sessions.
Comprehensive screening, clearly defined inclusion criteria, and direct physician oversight on 100% of treatment dives.
60 total sessions in rigid, steel chambers at therapeutic pressures between 1.5 and 2.4 ATA, with pre- and post-protocol assessments.
Hyperbaric Therapy
Hyperbaric oxygen therapy (HBOT) is a non‑invasive treatment in which a patient breathes 100% medical‑grade oxygen at increased atmospheric pressure inside a rigid, hospital‑grade chamber.

By combining 100% oxygen with elevated pressure, HBOT dissolves oxygen directly into the plasma and other body fluids, not just red blood cells. This creates a temporary state of “hyper‑oxygenation” that can support tissue repair and resilience.
In our medical‑grade chambers, pressures typically range from 1.5 to 2.4 ATA, allowing oxygen levels in the body to increase dramatically compared to normal breathing at sea level.
Individual responses vary, and HBOT is used as an adjunctive therapy within a broader medical plan.

While each plan is tailored to the individual, most participants move through the following steps when beginning hyperbaric therapy at the National Hyperbaric Medicine Institute.
Our medical team reviews your history, goals, and current treatments to determine whether HBOT is an appropriate option.
A protocol is designed around your needs, including the number of dives, pressure targets, and integration with your existing care.
Sessions typically last around 90 minutes, during which you can rest, listen to music, or watch programming inside the chamber.
Throughout and after the protocol, progress is reviewed using symptom scales, functional measures, and physician follow‑up.
The questions below address how HBOT feels, who it may be appropriate for, and how our 60‑session protocol compares with shorter treatment plans.

The Food and Drug Administration (FDA) currently recognizes hyperbaric oxygen therapy (HBOT) for a specific set of conditions, which are generally covered by insurance. HBOT may also have benefits for other conditions not yet approved by the FDA. Many of those conditions have undergone significant research and are commonly treated with HBOT around the world. Treatment for conditions not yet approved by the FDA is generally not covered by insurance and is often not available at hospital-based hyperbaric centers.
As an independent clinical institute, NHMI is able to accommodate the needs and circumstances of patients whom our physicians believe may benefit from HBOT. In circumstances in which insurance coverage is not available, several payment options and financial assistance programs may be available. A list of FDA-approved conditions and others that have not yet gained FDA approval are outlined below.
Also referred to as on-label, these conditions have been approved by the FDA for HBOT and are generally covered by insurance.

Conditions that have not yet been approved by the FDA. In general, off-label conditions are not covered by insurance.
The NHMI 60-session protocol is designed as a structured, physician-led process. The outline below describes the typical journey from first contact through post-study review.
Exact visit length, pricing, and insurance details can be refined with the clinical and billing teams, but this framework reflects how patients move through the protocol.
Prospective participants connect with a clinical intake coordinator for a 15–30 minute call to review goals, relevant history, and whether HBOT is likely to be appropriate.
Formal intake paperwork, prior imaging, medication lists, and lab work are collected and summarized for the physician team before the consultation.
A hyperbaric physician reviews contraindications, answers questions, and confirms whether the 60‑session protocol is medically appropriate.
When indicated, baseline assessments such as cognitive testing, functional questionnaires, or imaging are completed to allow for objective before‑and‑after comparison.
Participants complete a structured schedule of high‑pressure oxygen sessions—typically five days per week—under continuous clinical supervision.
At the conclusion of the protocol, results, symptom changes, and follow‑up options are reviewed with the physician, including recommendations for longer‑term maintenance.
For FDA‑approved indications, the clinic bills a patient’s insurance when possible, with co‑pays and deductibles determined by each individual plan. Pre‑authorization and documentation requirements are reviewed before treatment begins.
For conditions not yet covered by insurance, NHMI offers structured self‑pay programs, typically organized as a 60‑session protocol with transparent pricing and no surprise fees.
Patients may be able to spread costs over time through third‑party financing or internal payment plans, and limited need‑based assistance may be available for qualifying cases.
On treatment days, participants check in with clinical staff, complete a brief symptom and vital sign review, and are prepared for the chamber by the hyperbaric team. Once inside the chamber, pressure is gradually increased to the prescribed level and 100% oxygen is delivered for the duration of the dive.
After each session, patients are monitored as they return to baseline, review any changes with staff, and schedule the next visit in their series.
Specific timing, clothing recommendations, and medication guidelines can be added once standardized by the clinical team.
The National Hyperbaric Medicine Institute (NHMI) was established to bring clinical integrity to the field of regenerative oxygen therapy.
Our approach is defined by Patient Selection. We believe the 60-session protocol is a high-level intervention that requires a serious commitment. Our facility is led by board-certified physicians specializing in hyperbaric medicine, ensuring that every participant's journey is safe, monitored, and evidence-based.

NHMI follows established hyperbaric safety guidelines, including comprehensive review of pulmonary history, ENT status, cardiac risk, and implanted devices before the first dive.
Final contraindication lists and clearance criteria can be refined by the medical team to align with institutional policy.
A growing body of peer‑reviewed literature supports the use of HBOT for both on‑label and emerging indications, including complex wounds, radiation tissue injury, and selected neurological conditions.
Specific study citations and internal outcome data can be added here as the clinic’s research and quality‑assurance programs mature.
NHMI commits to evidence‑informed practice, ethical patient selection, and ongoing collaboration with referring physicians and research partners.
