A Doctor Who Uses Both
Dr. Palacios practices internal and functional medicine. He is not a theorist. He treats patients every day. And he has used both hyperbaric oxygen therapy (HBOT) and LiveO2 in clinical settings.
That makes him rare. Most people who talk about HBOT vs LiveO2 have only used one. Dr. Palacios has used both. So when he compares them, he is comparing real results with real patients.
That distinction matters. Because the difference between these two approaches is not small. It is fundamental.
The Pressure Question
Hyperbaric works by putting your entire body inside a pressurized chamber. The pressure forces oxygen into your blood plasma. More pressure means more dissolved oxygen.
Sounds good in theory. But there is a problem.
Your body does not live at high pressure. It lives at atmospheric pressure — about 14.7 PSI at sea level. When you leave the chamber, the extra pressure goes away. And so does the dissolved oxygen.
LiveO2 takes a different approach. Instead of forcing oxygen in with pressure, it uses your own circulatory system. You exercise. Your heart pumps faster. Your blood vessels open. Then you breathe concentrated oxygen at the exact moment your body can absorb the most.
“The body responds better when you work with its own systems rather than forcing oxygen in from the outside.”
— Dr. Palacios, MDResearch supports this. A 2019 review in the Journal of Applied Physiology found that exercise-induced vasodilation significantly increases oxygen transport to tissues — no pressure chamber required (PubMed 30789772).
What Atmospheric Pressure Actually Does
Dr. Palacios makes an important point about pressure. Your body already knows how to use oxygen at normal atmospheric pressure. It has been doing it your entire life.
The issue is not pressure. The issue is delivery.
When your blood vessels are inflamed or constricted, oxygen cannot reach the tissues that need it. Increasing pressure does not fix that. It just puts more oxygen into your blood. If the blood cannot get where it needs to go, the extra oxygen does not help.
LiveO2 fixes the delivery problem first. The Adaptive Contrast protocol briefly reduces oxygen. Your body responds by dilating blood vessels. Then you switch to high oxygen. The vessels are wide open. The oxygen floods in.
Hyperbaric increases the supply. LiveO2 opens the delivery route. That is the core difference.
This is why some people do 40 HBOT sessions and still feel the same. The oxygen never reached the tissue that was actually starving.
Practical Differences for Patients
Dr. Palacios also talks about the practical side. Hyperbaric sessions are long. Typically 60 to 90 minutes in the chamber. Most protocols call for 20 to 40 sessions. That is a serious time commitment.
LiveO2 sessions are 15 minutes. You exercise on a stationary bike or treadmill while breathing through a mask. You can do it every day if you want. Most people notice changes after their first session.
Cost is different too. A single HBOT session can run $150 to $300. A full protocol costs thousands. With LiveO2, you own the system. Use it as much as you want. No per-session fees.
For practitioners, the economics change everything. Dr. Palacios can run multiple patients through LiveO2 in the time it takes one patient to finish a hyperbaric session. That means more patients get helped. And the clinic generates more revenue.
A 2017 study in Medical Gas Research found that normobaric oxygen combined with exercise produced comparable tissue oxygenation to hyperbaric protocols in chronic wound patients (PubMed 29152215).
Working with Oxygen as a Practitioner
One thing Dr. Palacios emphasizes: oxygen is not a drug. You do not need a prescription. You do not need FDA clearance. Oxygen training is exercise — enhanced with concentrated oxygen.
That matters for practitioners. It means you can offer it to patients without navigating the regulatory maze that comes with hyperbaric. No special licensing. No chamber inspections. Just a system, a mask, and a stationary bike.
Dr. Palacios uses LiveO2 for patients dealing with chronic fatigue, brain fog, slow recovery, and general vitality loss. These are the patients who have tried everything and are still stuck. Oxygen training gives them something new to work with.
And because the system is simple, patients can eventually get their own system at home. That is the long game. You teach them in the clinic. They continue at home. Results compound over time.
Common Questions
Dr. Palacios is a physician practicing internal and functional medicine. He has clinical experience treating patients with both hyperbaric oxygen therapy and LiveO2 Adaptive Contrast.
HBOT uses a pressurized chamber to force oxygen into blood plasma. LiveO2 uses exercise and Adaptive Contrast to open blood vessels first, then delivers high-concentration oxygen through your own circulatory system at normal atmospheric pressure.
A LiveO2 session is about 15 minutes. A hyperbaric session typically runs 60 to 90 minutes. Most HBOT protocols require 20 to 40 sessions over several weeks.
Yes. LiveO2 is classified as exercise equipment, not a medical device. Practitioners can offer oxygen training sessions without the regulatory requirements that apply to hyperbaric chambers. Read about intended use.
Many people who seek HBOT for chronic fatigue, brain fog, slow recovery, and general vitality loss find similar or better results with LiveO2. The mechanism is different — LiveO2 focuses on opening delivery pathways rather than increasing pressure — but the goal is the same: getting more oxygen to the tissue that needs it.
A full HBOT protocol (20–40 sessions) can cost $3,000 to $12,000. LiveO2 is a one-time purchase. Once you own the system, there are no per-session fees. Most owners recover the cost within the first few months of use.
