Hyperbaric Oxygen Therapy

Hyperbaric Oxygen Therapy (HBOT): Uses, Benefits, Safety & Cost in India

What HBOT is, how it works, what it genuinely treats, and what a session feels like — the complete, evidence-based guide from HBOTLAB.

The Basics

What is hyperbaric oxygen therapy?

Hyperbaric oxygen therapy (HBOT) is a medical treatment in which you breathe near-100% oxygen inside a pressurised chamber, at a pressure higher than normal atmospheric levels (typically 1.5–3.0 ATA). At that pressure your blood carries far more dissolved oxygen than usual, so oxygen reaches tissues a normal breath cannot — which is why HBOT is used to speed healing, reduce inflammation and support recovery across a range of conditions.

“Hyperbaric” simply means “higher than normal pressure.” HBOT is an established hospital treatment for a defined list of conditions, and is also used as adjunctive (supportive) therapy in recovery, rehabilitation and wellness. For the plain-language primer, see what is hyperbaric oxygen therapy.

What does HBOT stand for? HBOT is the abbreviation for Hyperbaric Oxygen Therapy — so “HBOT”, “HBOT therapy”, “HBOT treatment” and hyperbaric oxygen therapy all mean the same thing: breathing pure oxygen inside a pressurised chamber. We use the short form HBOT throughout this guide.

The Science

How does HBOT work inside your body?

Normally almost all the oxygen you breathe is carried by haemoglobin in red blood cells, and that system is already close to full. HBOT changes the physics: raising the pressure forces extra oxygen to dissolve straight into the blood plasma and other body fluids, driving it deeper into tissue. This produces several documented effects:

  • Oxygen reaches oxygen-starved tissue — plasma can carry oxygen into swollen, injured or poorly perfused areas that red cells struggle to reach.
  • New blood-vessel growth (angiogenesis) — repeated sessions stimulate the body to build new capillaries, improving long-term blood supply to a wound or injury.
  • Reduced swelling and inflammation — high tissue-oxygen levels help control excess inflammation and reduce swelling.
  • Antimicrobial support — oxygen-rich tissue is hostile to certain bacteria and boosts white-cell killing power, part of why HBOT is used in specific serious infections.

Conditions & Uses

What does hyperbaric oxygen therapy treat?

HBOT is used across three tiers: internationally recognised medical indications, evidence-supported adjunctive uses, and emerging or wellness applications. It matters to be honest about which is which — and we are.

Recognised medical indications

There is a defined set of conditions for which HBOT is an accepted, evidence-backed treatment — including decompression sickness, carbon monoxide poisoning, gas gangrene and other serious infections, non-healing diabetic wounds, compromised skin grafts and flaps, radiation tissue injury, crush injuries and severe anaemia. See the full list in what HBOT is used for: the recognised indications explained.

Neurological support
Wound healing & diabetic care

One of HBOT’s strongest, best-evidenced roles is healing wounds that will not close on their own — especially diabetic foot ulcers, where improved tissue oxygen can reduce the risk of amputation.

Skin, longevity & recovery

For the wider picture, see our overview of scientifically supported HBOT benefits.

Outside the recognised medical indications, HBOT is a complementary therapy. It should support — never replace — the treatment prescribed by your doctor. Always discuss adjunctive HBOT with your treating specialist first.

Step by Step

What a hyperbaric oxygen therapy session is like

1

Initial Consultation

Before your first session, a member of our clinical team reviews your health history, current medications, and goals. This takes 15–20 minutes and ensures your programme is designed for you specifically — not a generic plan.

2

Preparing for the Session

You will be asked to wear comfortable, loose clothing — cotton is ideal. Avoid perfumes, oil-based products, and synthetic fabrics on session days. No special diet is required, though we recommend eating a light meal beforehand and staying hydrated.

3

Entering the Chamber

The chamber is clean, well-lit, and designed for comfort. Depending on the model at your centre, you may sit or recline. Many clients bring a book, listen to music, or use the session to simply rest. There is nothing to do except breathe normally.

4

Pressurisation

The session begins with a gentle pressurisation phase — typically 10 to 15 minutes. You may feel a slight pressure sensation in your ears, similar to what you experience in an aeroplane or when descending in a lift. Our team will show you a simple equalisation technique before your first session — most clients adapt quickly.

5

The Therapy Window

Once the target pressure is reached, your session is fully underway. This is where the therapeutic work happens. Duration varies by protocol — typically 60 to 90 minutes. Your chamber has a viewing window, and our team is always nearby.

6

Depressurisation

At the end of the session, pressure is gently reduced over 10 to 15 minutes. You simply continue resting. There is no abrupt change, no discomfort.

7

Post-Session

Most clients step out feeling refreshed, calm, and noticeably clearer. Some feel a gentle tiredness — this is normal and typically passes within an hour. You can drive, return to work, and continue normal activities immediately.

Client Experiences

In your own words — what clients actually report.

I expected it to feel clinical and uncomfortable. It was more like a nap I came out of feeling ten years younger.

— Member, Recovery Programme

The first session I was nervous. By the third, I looked forward to it. It became the calmest hour of my week.

— Athlete, Sports Recovery Programme

My doctor had given up on my wound. After 14 sessions here, it had closed by more than half. I still can’t fully explain it.

Programme Guide

Results build. Here is how to think about your programme.

HBOT is a therapy that compounds over time. A single session delivers benefit — but the real transformation happens over a course of sessions, as your body progressively responds and repairs. The right number of sessions depends entirely on your goal and your starting point.

Goal Typical Sessions Duration
Injury recovery support10–20 sessions2–4 weeks
Sports performance enhancement10–20 sessions2–4 weeks
Diabetic wound healing20–40 sessions4–8 weeks
Post-surgery healing support15–30 sessions3–6 weeks
Anti-ageing / cellular renewal20–40 sessions6–12 weeks
Neurological support20–60 sessions6–16 weeks
Cognitive performance20–40 sessions6–10 weeks
Mental wellness programme15–30 sessions4–8 weeks

Your HBOTLAB team will recommend a programme length during your initial consultation. There is no pressure to commit to a full programme upfront. We start with what makes sense and adjust as we see how you respond.

Safety

Is HBOT safe? Side effects and who should avoid it

Delivered in a properly certified chamber under trained supervision, HBOT has a strong safety record. Like any medical treatment it has side effects, and some people should not have it.

  • Common, usually mild: ear or sinus pressure (the most frequent effect), temporary changes in vision, and tiredness after a session.
  • Rare but serious: oxygen toxicity or lung/ear injury — which is exactly why pressure, duration and chamber standards matter.
  • Extra care or avoid: people with certain untreated lung conditions, recent ear surgery, or specific other conditions — this must be assessed individually before treatment.

Chambers & Standards

Soft chamber vs hard chamber — and why standards matter

Not all “HBOT” is equal. Hard chambers certified as pressure vessels for human occupancy (PVHO / ASME PVHO-1) reach the higher pressures (around 2.0 ATA and above) at which most clinical effects are documented. Soft/mild chambers at ~1.3 ATA are a different, gentler category. Knowing the difference protects both your safety and your money.

Cost in India

How much does hyperbaric oxygen therapy cost in India?

Pricing in India varies by city, chamber type (hard vs soft), pressure, session length and whether you buy a package. Because a genuine course involves multiple sessions, both the per-session price and the package price matter. We keep up-to-date, city-specific figures here rather than quote a single number that quickly goes stale:

FAQs

Hyperbaric oxygen therapy: your questions answered

What is the full form of HBOT?
HBOT stands for Hyperbaric Oxygen Therapy. It means breathing near-100% oxygen inside a pressurised chamber (typically 1.5–3.0 ATA) to drive far more oxygen into the blood and tissues than normal breathing allows.
What is hyperbaric oxygen therapy used to treat?
HBOT is a recognised treatment for conditions including decompression sickness, carbon monoxide poisoning, serious infections such as gas gangrene, non-healing diabetic wounds, compromised skin grafts and flaps, radiation tissue injury, crush injuries and severe anaemia. It is also used as adjunctive support in neurological recovery, wound care and rehabilitation.
How does hyperbaric oxygen therapy work?
Raising the pressure inside the chamber forces extra oxygen to dissolve directly into your blood plasma, so it can reach tissues a normal breath cannot. Over a course of sessions this reduces swelling, stimulates new blood-vessel growth and supports healing.
Is hyperbaric oxygen therapy safe?
In a certified chamber under trained supervision, HBOT is generally safe. The most common side effect is temporary ear or sinus pressure. Serious complications are rare and are minimised by correct pressure, session length and chamber standards. Some people should not have HBOT without specialist assessment.
What is the most common side effect of HBOT?
The most common side effect is a feeling of pressure or discomfort in the ears or sinuses during pressurisation — similar to a flight or a fast lift — which is managed with simple equalising techniques.
How long does a hyperbaric oxygen therapy session last?
A typical session runs about 60–90 minutes at target pressure, plus a short pressurisation and depressurisation phase. Most treatment plans involve a course of 20–40 sessions, because the benefits accumulate over repeated exposures.
Does insurance cover hyperbaric oxygen therapy in India?
Coverage depends on your insurer, policy and the medical indication. HBOT for a recognised medical condition prescribed by a doctor is more likely to be considered than elective or wellness use. Confirm in writing with your insurer before starting, and ask the clinic for the documentation they can provide.
Who should not use hyperbaric oxygen therapy?
HBOT may not be suitable for people with certain untreated lung conditions, recent ear or sinus surgery, or specific other medical situations. Suitability is always decided by individual clinical assessment before your first session — always disclose your full medical history and medications.
How much does hyperbaric oxygen therapy cost in India?
Cost varies by city, chamber type, pressure and package. See our up-to-date HBOT cost in India guide and city-specific pages for current figures.

Common Questions

Practical questions — answered honestly.

Can I use my phone during the session?
Electronic devices are generally not permitted inside the chamber due to the oxygen-enriched environment. Most clients use the session as a break from screens — many say this is one of the unexpected benefits.
What if I feel claustrophobic?
Our team will walk you through the chamber before your first session and let you get comfortable at your own pace. The chambers are well-lit and have a clear viewing window. Most people who expect claustrophobia find the experience more comfortable than anticipated. If needed, we can do a short acclimatisation session before starting your programme.
Can I bring a family member?
Absolutely. Family members are welcome to wait at the centre. For children undergoing therapy, a parent or guardian is present throughout.
Can I eat before a session?
Yes — a light meal 1–2 hours before is ideal. Avoid heavy, fatty meals immediately before a session. Stay well hydrated.
Is there anything I cannot do before a session?
Avoid alcohol in the 24 hours before a session. If you are unwell with an active respiratory infection, inform our team — they may advise postponing until you recover.
