Dr. Angelique Hart — 5 Years of Patient Results
An MD shares what she learned using LiveO2 with hundreds of patients. Brain recovery. Immune support. Athletic performance. All from 15 minutes a day.
What 5 Years of Clinical Use Looks Like
Dr. Hart didn’t try LiveO2 once and move on. She built her practice around it.
Dr. Angelique Hart, MD, has been using LiveO2 in her Albuquerque practice for over five years. She started with a simple question: could oxygen training make her other treatments work better? Five years and hundreds of patients later, the answer is clear.
Brain Function Changes That Showed Up Fast
The first thing Dr. Hart noticed was the brain. Patients with traumatic brain injuries, chronic brain fog, and cognitive decline were improving faster than expected. Not slightly. Noticeably.
Here’s why that makes sense. Your brain weighs about 3 pounds. It uses 20% of your total oxygen supply. When oxygen delivery drops — from injury, age, inflammation, or poor circulation — the brain is the first organ to suffer.
LiveO2’s Adaptive Contrast protocol creates a brief low-oxygen challenge that forces blood vessels open. Then it floods those wide-open vessels with high-concentration oxygen. The brain gets oxygen at levels it hasn’t seen since you were a teenager.
A study published in Frontiers in Aging Neuroscience found that improved cerebral blood flow and oxygenation are directly linked to better cognitive performance in aging adults (PubMed 25653617).
It Makes Everything Else Work Better
This is the insight that changed how Dr. Hart practices medicine. LiveO2 isn’t a standalone treatment. It’s a multiplier.
Think about it. Every medication you take has to reach your cells through your bloodstream. Every supplement has to be absorbed, transported, and delivered. Every therapy depends on blood flow to carry the healing signal to the right place.
“When you improve oxygen delivery first, every other treatment in your protocol works better. It’s the one thing that amplifies everything else.”
— Dr. Angelique Hart, MDIf the delivery system is broken — if your blood vessels are inflamed, constricted, or damaged — then nothing you take can reach its full potential. Fix the oxygen delivery problem and suddenly the same treatments start producing better results.
That’s not a guess. That’s what Dr. Hart observed across hundreds of patients over five years. The patients who did LiveO2 sessions before or alongside other treatments consistently improved faster.
Legal, Ethical Performance Enhancement
Here’s something athletes care about: LiveO2 creates a performance boost that is completely legal and ethical. No banned substances. No gray areas. Just better oxygen delivery to working muscles.
Dr. Hart has seen this in her athlete patients. VO2 max goes up. Recovery time goes down. Endurance improves. And it all comes from a 15-minute session on a bike or treadmill.
Men typically gain about 50 watts of aerobic output — the equivalent of rolling back their performance age by roughly 20 years. That’s not a supplement. That’s not a drug. That’s oxygen.
The mechanism is straightforward. Adaptive Contrast trains your vascular system to dilate more efficiently. Over time, your body gets better at delivering oxygen under load. It’s the same principle behind altitude training — except you get the benefit in 15 minutes instead of weeks at a training camp.
Research in the British Journal of Sports Medicine has demonstrated that enhanced oxygen availability during exercise significantly improves both peak power output and time to exhaustion (PubMed 17317766).
Oxygen and Immune Function
Dr. Hart also uses LiveO2 to support immune function. The connection is direct: your white blood cells need oxygen to fight infections. They use reactive oxygen species — free radicals — to destroy bacteria and viruses.
When oxygen delivery is compromised, your immune system runs on empty. It’s like trying to start a fire with wet wood. All the sparks in the world won’t help if there’s no oxygen to feed the flame.
LiveO2 restores that capacity. By flooding the body with oxygen during exercise, it gives immune cells the fuel they need to do their job. Dr. Hart has seen patients recover from chronic infections faster, bounce back from illness quicker, and maintain better overall resilience.
What Doctors Need to Know
After five years, Dr. Hart’s message to other physicians is simple: oxygen training is the missing piece in most treatment protocols.
It’s not a replacement for what you’re already doing. It’s what makes everything you’re already doing work better. Brain injury recovery. Chronic disease management. Athletic performance. Immune support. All of these improve when oxygen delivery is optimized first.
The best part? Patients feel the difference immediately. It’s not something they have to take on faith for six months. Most people notice clearer thinking, more energy, and better mood after the very first session. That kind of immediate feedback keeps patients engaged and consistent — which is half the battle in any treatment plan.
Common Questions
Dr. Angelique Hart is a practicing MD in Albuquerque, New Mexico. She has been using LiveO2 in her clinical practice for over five years, treating hundreds of patients with conditions ranging from brain injuries to chronic fatigue to athletic performance optimization.
During an Adaptive Contrast session, the combination of exercise-driven blood flow and high-concentration oxygen can deliver oxygen to brain tissue at levels far above what normal breathing provides. The “24x” figure refers to peak oxygen availability in brain tissue during the protocol.
Dr. Hart has observed improvements in patients with traumatic brain injuries and cognitive decline. Oxygen training may support brain recovery by restoring blood flow and oxygen delivery to affected areas. Results vary by individual, and LiveO2 is not a medical device. See the BrainO2 protocol.
Every medication, supplement, and therapy depends on blood flow to reach its target. When oxygen delivery is compromised, treatments can’t reach their full potential. By improving vascular function and oxygen transport, LiveO2 may help other interventions work more effectively.
Yes. LiveO2 uses concentrated oxygen and exercise — no banned substances, no drugs, no gray areas. It creates a performance boost through better oxygen delivery, which is completely legal and ethical for competitive athletes.
