When a child experiences a birth injury affecting the brain, parents understandably explore every available treatment that might support healing and recovery. Hyperbaric oxygen therapy is one option that families may hear about, either from medical teams treating acute complications or through their own research into therapies for conditions like cerebral palsy or hypoxic-ischemic encephalopathy.
This page explains what hyperbaric oxygen therapy is, which conditions it reliably treats, what the current research shows for birth-related brain injuries, and how families in New York and across the country can access evidence-based guidance when considering this therapy.
What Hyperbaric Oxygen Therapy Is and How It Works
Hyperbaric oxygen therapy, often abbreviated HBOT, involves breathing 100% pure oxygen inside a specially designed pressurized chamber. The pressure inside the chamber is raised above normal atmospheric levels, typically measured in atmospheres absolute (ATA). This combination of increased pressure and pure oxygen allows far more oxygen to dissolve directly into the bloodstream than would be possible under normal conditions.
The goal is to deliver higher concentrations of oxygen to tissues that are injured, oxygen-starved, or fighting infection. In theory, this boost in oxygen availability can support cellular repair processes, reduce inflammation, and promote healing in areas where blood flow has been compromised.
HBOT sessions typically last 60 to 90 minutes and are conducted in accredited medical facilities under careful supervision. Pediatric protocols follow strict safety guidelines to minimize risks and tailor treatment to each child’s medical needs.
Medical Conditions That Benefit from Hyperbaric Oxygen Therapy
The U.S. Food and Drug Administration and major medical organizations recognize hyperbaric oxygen therapy as a proven treatment for a specific set of conditions. These include:
- Carbon monoxide poisoning
- Air or gas embolism
- Decompression sickness
- Certain chronic, non-healing wounds
- Severe infections such as necrotizing fasciitis
- Crush injuries and acute traumatic ischemia
In pediatric care, HBOT is most often used for acute poisoning cases, gas embolism, or wound complications. For these approved indications, the therapy is considered both safe and effective when delivered by trained providers in hospital-based hyperbaric centers.
Insurance coverage is typically available for FDA-approved uses, and treatment protocols are standardized across accredited facilities.
Investigational Use for Birth Injuries and Brain Conditions
Families of children with hypoxic-ischemic encephalopathy, cerebral palsy, or other birth-related brain injuries sometimes ask whether hyperbaric oxygen therapy might help. The appeal is understandable: if oxygen deprivation caused the injury, could extra oxygen support recovery?
The short answer is that the evidence remains unclear and insufficient for clinical recommendation outside of research trials.
While there is a biological rationale for why HBOT might benefit oxygen-deprived brain tissue, studies to date have not provided the level of proof required by U.S. and European medical guidelines. The American Academy of Pediatrics, the Centers for Disease Control and Prevention, the National Institutes of Health, and the World Health Organization do not endorse routine use of HBOT for HIE, birth asphyxia, or cerebral palsy.
Most published research comes from small studies or case series, many conducted outside the United States, and results have been inconsistent. Some families report perceived improvements in muscle tone, alertness, or developmental milestones, but these observations have not been confirmed in large, controlled clinical trials that meet rigorous scientific standards.
Recent Research on Hyperbaric Oxygen Therapy for Neonatal Brain Injury
A 2024 meta-analysis reviewed 46 randomized controlled trials involving nearly 4,200 infants with hypoxic-ischemic encephalopathy, the majority of whom were treated in China. The analysis found that HBOT, when carefully monitored, was associated with improved treatment response and reduced neurological complications.
However, the authors and independent reviewers noted important limitations. Many of the included studies had methodological weaknesses, varying definitions of outcomes, and differences in how HBOT was delivered. Additionally, results from populations in China may not directly translate to infants in the United States or Europe, where baseline care protocols, genetic backgrounds, and healthcare systems differ.
Smaller case series from neonatal centers in developed countries have documented that HBOT can be delivered safely to infants, with most adverse events being mild and manageable. In one series, 74% of infants treated for acute poisoning or embolism recovered fully, with no serious side effects observed.
Still, these promising findings have not yet led to changes in clinical practice guidelines. Research is ongoing, and several U.S. medical centers are conducting or participating in controlled trials to better understand whether HBOT offers meaningful benefit for infants with birth-related brain injuries.
How Hyperbaric Oxygen Therapy Is Delivered Safely to Children
When hyperbaric oxygen therapy is performed in an accredited facility following established protocols, it is generally safe for infants and children. Adverse events are uncommon and typically mild.
The most frequently reported side effects include:
- Ear or sinus discomfort from pressure changes (barotrauma)
- Temporary changes in vision
- Feelings of anxiety or claustrophobia in older children
More serious risks, such as oxygen toxicity or seizures, are extremely rare when treatment is carefully controlled. Pediatric protocols for investigational use in brain injury typically involve pressures of 1.4 to 1.6 ATA, which are considered safe under close observation.
Medical staff monitor the child throughout each session, adjusting pressure gradually and watching for signs of distress or discomfort. Parents are often permitted to stay nearby, and some chambers are designed to accommodate a caregiver inside with the child.
Safety depends heavily on the experience and expertise of the hyperbaric team. Families considering HBOT should seek treatment only at accredited centers with pediatric experience and established safety protocols.
Access to Hyperbaric Oxygen Therapy in New York and Major Medical Centers
Several leading hospitals in New York operate advanced hyperbaric medicine programs. These include Mount Sinai, NYU Langone Health, Columbia University Irving Medical Center, and Albany Medical Center.
These institutions follow evidence-based protocols and prioritize FDA-approved indications for HBOT. When a child’s condition falls outside approved uses, such as investigational treatment for cerebral palsy or neonatal brain injury, therapy is offered only within the framework of formal clinical research trials.
Families interested in exploring HBOT for a birth injury are typically referred through a multidisciplinary team that may include neurologists, neonatologists, developmental pediatricians, and rehabilitation specialists. These teams help determine whether a child might be eligible for a clinical trial and provide transparent information about risks, potential benefits, and alternatives.
ClinicalTrials.gov is a publicly accessible database where families can search for active studies involving hyperbaric oxygen therapy and pediatric neurological conditions. Many trials are conducted in partnership with major academic medical centers and include comprehensive consent processes and safety monitoring.
Insurance Coverage and Financial Considerations
Insurance companies generally cover hyperbaric oxygen therapy only for FDA-approved indications. This means that treatment for carbon monoxide poisoning, gas embolism, or certain infections is likely to be covered, while investigational use for conditions like cerebral palsy or HIE typically is not.
Out-of-pocket costs for HBOT can be substantial, especially when multiple sessions are needed. Families considering treatment outside of a clinical trial should request detailed cost estimates and verify coverage with their insurer before beginning therapy.
Some families pursue HBOT at private or outpatient hyperbaric centers that market the therapy for a wide range of conditions. It is important to distinguish between accredited hospital-based programs that follow rigorous safety and research standards and facilities that may make unsubstantiated claims or lack appropriate pediatric expertise.
Families are encouraged to consult with their child’s medical team and to ask about participation in research trials, which often provide treatment at no cost and include close medical oversight.
What Families Should Know Before Considering Hyperbaric Oxygen Therapy
If you are considering hyperbaric oxygen therapy for a child with a birth injury, here are key points to keep in mind:
Start with your child’s care team. Pediatric neurologists, developmental specialists, and therapists can help you understand which treatments are supported by evidence and which are still under investigation.
Ask about clinical trials. If HBOT is being considered for a non-approved indication, inquire whether your child might qualify for a research study at a major medical center. Trials provide structure, oversight, and transparency.
Verify credentials and accreditation. Seek treatment only at facilities accredited by the Undersea and Hyperbaric Medical Society or similar recognized bodies, with staff experienced in pediatric care.
Understand the limitations. While HBOT is safe and effective for certain conditions, its role in treating birth-related brain injuries remains unproven. No major pediatric guideline currently recommends routine use for HIE, cerebral palsy, or developmental delay.
Be cautious of unsupported claims. Marketing materials that promise dramatic improvements or present HBOT as a cure should be viewed with skepticism. Reputable providers will discuss both potential benefits and uncertainties.

Current Medical Consensus on Hyperbaric Oxygen Therapy for Birth Injuries
Hyperbaric oxygen therapy is a valuable, lifesaving treatment for select pediatric emergencies, particularly poisoning, embolism, and certain infections. In these contexts, it is considered standard of care and is widely available at accredited medical centers.
Its use for brain injury related to birth asphyxia, hypoxic-ischemic encephalopathy, or cerebral palsy remains investigational. While early research suggests a possible benefit, the evidence is not yet strong or consistent enough to support routine clinical use outside of research settings.
No major pediatric or neonatal guideline from organizations such as the American Academy of Pediatrics, the Centers for Disease Control and Prevention, or the National Institutes of Health endorses HBOT for these conditions at this time. Ongoing studies continue to evaluate safety and efficacy, and future findings may change clinical practice.
Families interested in hyperbaric oxygen therapy for a birth injury should seek guidance from specialists at established medical centers, consider participation in formal clinical trials, and carefully weigh the evidence, risks, and realistic expectations before proceeding.
