What Happens During an EBOO Session? A Step-by-Step Guide

If you're trying to picture what happens during an EBOO session, most descriptions online jump straight into technical language. This guide walks through it in plain steps — from the moment you sit down to the moment you leave — so you know what to actually expect, what the evidence does and doesn't support, and what questions are worth asking before you book.

EBOO stands for extracorporeal blood oxygenation and ozonation. That's a long way of saying: blood leaves your body, passes through a machine that adds oxygen and ozone gas, then goes back in. It's related to older ozone therapy methods but uses more equipment and takes longer.

What happens during an EBOO session, step by step?

During an EBOO session, a provider places two IV lines — one to draw blood, one to return it — and blood is pumped out through tubing into a machine that exposes it to oxygen and ozone gas before returning it to your body. The whole cycle typically runs while you sit or recline, and the process is closed, meaning your blood does not sit exposed in an open container.

Here's how that breaks down in practice.

Step 1: Intake and health screening

Before any needle goes in, a provider should review your health history. This is the point where conditions like G6PD deficiency, bleeding disorders, pregnancy, or use of blood thinners need to come up — because these change whether EBOO is appropriate at all. One competitor source describes this stage as including a review of lab work and medical history before treatment begins.

If a provider skips this step or waves it off, that's worth treating as a red flag, not a time-saver.

Step 2: Setting the lines

Two IV access points are set — usually one in each arm, or two sites on the same arm depending on the equipment. One line draws blood out. The other returns it once it's been through the machine. This part feels like a standard blood draw or IV insertion: a brief pinch, then pressure at the site.

Step 3: Blood is drawn through the circuit

Blood is pulled by a pump through sterile tubing into the EBOO device. Inside the machine, it's exposed to a mixture of oxygen and ozone gas. This is the part that separates EBOO from simpler ozone methods — the blood is processed continuously through a closed circuit rather than being drawn into a bag, treated, and reinfused in batches.

Step 4: Blood is returned

Once treated, the blood flows back into your body through the second line. Because this happens in a continuous loop rather than all at once, the session takes time — competitor sources describing EBOO and the related EBO2 method note sessions lasting around two hours.

Step 5: Monitoring and recovery

You'll typically stay seated or reclined for monitoring during the full cycle. Afterward, most descriptions suggest a short rest period before leaving, similar to what you'd expect after a lab draw involving multiple vials or an IV infusion.

How is EBOO different from other ozone therapies?

EBOO is one of several ozone administration methods, and it's the most equipment-intensive one. The table below compares it to two simpler, more commonly discussed forms.

Method	How it works	Equipment needed	Session complexity
EBOO	Continuous closed-circuit pumping of blood through an ozone/oxygen exposure machine and back	Dedicated EBOO machine, two IV lines	Higher — longer session, more monitoring
Major autohemotherapy	A bag of blood is drawn, mixed with ozone gas, then reinfused	Ozone generator, blood collection bag	Moderate — single draw and reinfusion cycle
Minor autohemotherapy	A small amount of blood is drawn, ozonated, and injected intramuscularly	Ozone generator, small syringe	Lower — smallest blood volume involved

This is a structural comparison of process, not a claim that any of these therapies is proven to treat a condition. None of that should be read as an endorsement of effectiveness — it's simply what differentiates the delivery methods described across ozone therapy literature and provider sites.

What does the evidence actually say?

This is where a lot of marketing pages get vague, so it's worth being direct.

• Extracorporeal blood oxygenation and ozonation has been studied as a technique, with a paper indexed on PubMed describing the method itself (PubMed, 2005). Having a description of a technique in the literature is not the same as that technique being proven effective for a specific condition.
• Ozone-based blood treatment has been studied in dialysis contexts, where researchers found ozone dialysis delivered a measurably different toxin-clearance profile compared to standard dialysis in the specific study conditions examined (PMC/NIH, 2022). This is a specific, narrow research context — dialysis patients — not a general finding about ozone therapy for wellness purposes.
• A review of ozone's proposed mechanisms describes what researchers believe ozone does biologically, distinguishing proposed mechanisms from confirmed clinical outcomes (PMC/NIH, "The Actual Six Therapeutic Modalities").
• A study on urinary toxin excretion following ozone-related treatment reported an observed reduction in specific circumstances (PMC/NIH) — again, a specific, narrow finding, not a general claim about detoxification.

The honest summary: parts of the mechanism have been studied, some narrow clinical contexts show measurable effects, and broad wellness claims ("boosts immunity," "detoxifies the blood," "reverses aging") go well beyond what any of these sources establish. Treat those claims, wherever you see them, as unsubstantiated unless a specific study is named.

Risks and who should avoid this

This is the part that matters most, and it should never be buried.

Documented risks and side effects:

• Ozone is a reactive, toxic gas at the wrong concentration or exposure route. A review of ozone's potential toxicity outlines specific side effects and safety concerns tied to dose and administration method (PMC/NIH).
• Serious neurological complications have been documented following intravenous ozone therapy in at least one reported case, described in a peer-reviewed case report (PMC/NIH). This is a single documented case, not a statement about how common such events are — but it establishes that serious harm is possible, not theoretical.
• Standard IV-related risks apply: bruising, infection risk at the puncture site, and vein irritation.

Who should not have this therapy:

• People with G6PD deficiency — this is flagged specifically in ozone safety literature as a condition where ozone exposure can trigger dangerous red blood cell breakdown.
• People with active bleeding, bleeding disorders, or on blood-thinning medication, since the procedure involves extracorporeal blood handling.
• People who are pregnant.
• People with hyperthyroidism or uncontrolled thyroid conditions.
• Anyone who has not discussed the therapy with their prescribing physician, especially if they're on other medications.

Questions to ask before you go ahead:

• What are the specific qualifications of the person operating the equipment?
• What screening will be done before I'm accepted as a candidate?
• What happens if I feel unwell during the session?
• Is this treatment used here as a stand-alone therapy or alongside something else my doctor has prescribed?

If a clinic cannot answer these clearly, that is information too.

What to ask about, and where to look next

EBOO is a longer, more equipment-heavy version of ozone therapy, built around continuous blood circulation through a machine rather than a single treated batch. The process itself — draw, circuit, return, monitor — is fairly consistent across providers. What varies is screening rigor, equipment, and how honestly the expected effects are described to you.

If you're researching this for yourself, ask direct questions about screening, staffing, and what the treatment is and isn't expected to do — and treat any claim of a cure or guaranteed outcome as a reason to ask more questions, not fewer.

Frequently Asked Questions

How long does an EBOO session take?

Search results describing EBOO and related EBO2 sessions put a typical session at around two hours, though exact timing depends on the clinic and equipment used.

Is EBOO the same as regular ozone therapy?

No. EBOO circulates blood outside the body through a machine, while simpler methods like major autohemotherapy mix ozone into a drawn blood bag and reinfuse it without a circuit.

Does EBOO hurt?

The main sensation reported is similar to a blood draw or IV line at the needle sites. Ask your provider directly what sensations are typical with their setup.

Who should not get EBOO?

People with G6PD deficiency should not have ozone therapy, per documented safety literature. Anyone with bleeding disorders, active bleeding, hyperthyroidism, pregnancy, or on blood thinners should discuss risks with a doctor first.

Is EBOO FDA-approved?

The search results and verified sources provided do not state FDA approval status for EBOO. Ask the clinic directly about the regulatory status of the specific therapy they offer.
