The frequency of hyperbaric oxygen therapy sessions varies depending on the condition being treated, the severity of the medical issue, and individual patient factors. Understanding the typical treatment schedules and how therapy works can help you develop realistic expectations and work with your healthcare provider to create a personalized treatment plan.
Read on to find out how often you may need to receive hyperbaric oxygen therapy, what factors influence treatment frequency, and what to expect during your HBOT sessions.

Common Treatment Protocols and Frequency of HBOT
Most hyperbaric oxygen therapy treatment plans involve multiple sessions per week, with daily treatments being the most common approach. Typically, patients receive HBOT sessions five days a week, often Monday through Friday, with each hyperbaric oxygen therapy session lasting about 60 to 90 minutes inside a monoplace or multiplace hyperbaric oxygen therapy chamber.
People undergo HBOT to treat a variety of medical conditions, including asthma, non-healing wounds, carbon monoxide poisoning, decompression sickness, and radiation injuries. These treatments are usually available at specialized hyperbaric medical centers, hospitals, wound care clinics, and wellness centers equipped with the necessary pressurized chambers and licensed professionals.
For many conditions, the number of treatment sessions ranges from 20 to 40 treatments, although this can vary widely. For example:
- Acute conditions such as carbon monoxide poisoning or decompression sickness often require immediate and multiple daily sessions initially, followed by a tapering schedule as the patient improves.
- Chronic conditions like non-healing wounds or radiation injuries generally require daily sessions five days per week over several weeks to months.
- Neurological conditions such as traumatic brain injury may have treatment frequencies tailored to the patient’s response, with some protocols recommending daily sessions and others fewer per week.
- For wellness or anti-aging purposes, some people may receive HBOT once or twice a week, focusing on maintenance rather than intensive healing.
Factors That Influence the Frequency of Hyperbaric Oxygen Therapy
Condition being treated
Medical conditions like carbon monoxide poisoning require urgent, frequent treatments, while wound healing may need a longer course of daily sessions.
Severity of the condition
More severe or extensive tissue damage often means more sessions to maximize the benefits of HBOT.
Patient’s overall health and response
Some individuals may show noticeable benefits early, allowing for adjustments in frequency, while others need more prolonged treatment.
Treatment goals
Whether the goal is to promote natural healing, reduce inflammation, or improve oxygen levels in damaged tissue influences how often therapy is scheduled.
Type of hyperbaric chamber
Treatment protocols can vary slightly depending on whether a monoplace chamber (single patient) or multiplace chamber (multiple patients) is used.
What Happens During a Hyperbaric Oxygen Therapy Session?
During an HBOT session, the patient enters a hyperbaric oxygen therapy chamber where the air pressure is increased to about two to three times higher than normal air pressure. The patient breathes pure medical-grade oxygen, which significantly raises the oxygen levels in the blood and tissues.
This increased oxygen concentration helps repair damaged tissue, stimulate the growth of new blood vessels, and activate growth factors and stem cells essential for healing.
Each session typically lasts between 60 and 120 minutes, and patients may receive many sessions over the course of treatment to achieve the desired effects. The effects of hyperbaric oxygen therapy accumulate over time, therefore, consistency and adherence to the prescribed frequency are crucial for success.
Adjusting Treatment Frequency and Duration
A personalized treatment plan is essential to maximize the benefits of HBOT. Licensed hyperbaric medicine professionals continuously monitor patient progress and may adjust the frequency of sessions based on:
- Improvement in symptoms or wound healing
- Side effects such as oxygen toxicity or discomfort inside the chamber
- Patient tolerance and overall health status
Sometimes, after an initial intensive phase with daily sessions, the frequency may decrease to maintenance levels, such as one session per week, to sustain healing and prevent relapse.
Safety Considerations and Potential Side Effects
While HBOT is generally safe, the frequency and duration of treatments must be carefully managed to avoid potential side effects like oxygen toxicity or barotrauma (pressure-related injuries). Medical supervision ensures that the amount of oxygen and air pressure used during therapy is appropriate for the patient’s condition and treatment goals.

Practical Tips for Patients Receiving HBOT
To get the most out of your hyperbaric oxygen therapy, it’s important to follow your healthcare provider’s recommended treatment schedule closely.
Preparing for each session by wearing comfortable, cotton clothing and avoiding lotions, oils, or any skin care products helps ensure safety inside the hyperbaric chamber. Staying well-hydrated before and after therapy supports your body’s healing process, and promptly communicating any discomfort or side effects to your medical team allows for timely adjustments to your treatment plan.
Keep in mind that multiple HBOT sessions are often necessary to achieve noticeable benefits, so consistency and adherence to your personalized therapy schedule are key to maximizing the effects of hyperbaric oxygen therapy.
