Hyperbaric oxygen therapy (HBOT) involves breathing pure oxygen in a pressurized environment, traditionally at pressures greater than 1 atmosphere absolute (ATA). While higher pressures have been standard, emerging research indicates that lower-pressure HBOT can offer significant benefits for the nervous system and brain health.
Understanding Hyperbaric Oxygen Therapy
HBOT increases the amount of oxygen dissolved in the blood, enhancing oxygen delivery to tissues, including the brain. This elevated oxygenation can promote healing, reduce inflammation, and support neurogenesis—the formation of new neurons.
Benefits of Lower-Pressure HBOT for the Nervous System
Recent studies suggest that administering HBOT at lower pressures can be particularly advantageous for neurological health:
- Enhanced Neuroplasticity: Neuroplasticity is the brain’s ability to reorganize itself by forming new neural connections. A review in Frontiers in Neurology highlighted that HBOT can modulate neuroplasticity, potentially improving outcomes in various neurological conditions through multiple cellular mechanisms.

- Improved Cognitive Function: A systematic review published in Neuropsychology Review discussed the impact of HBOT on cognitive functions. The review analyzed various studies and suggested that HBOT could have positive effects on cognitive performance, although further research is needed to establish optimal protocols. Springer Link
- Increased Cerebral Blood Flow: A study in Neurological Sciences investigated the effects of low-pressure HBOT on cerebral blood flow in individuals with mild traumatic brain injury and emotional distress. The findings indicated that low-pressure HBOT might increase regional cerebral blood flow in the hippocampal and parahippocampal regions, which are critical for memory and emotional regulation.

Advantages of Lower Pressure in HBOT
Utilizing lower pressures in HBOT offers several potential benefits:
- Reduced Risk of Oxygen Toxicity: High-pressure oxygen exposure can lead to oxygen toxicity, affecting the central nervous system and lungs. Lower pressures may mitigate this risk, making therapy safer for patients.
- Improved Patient Comfort: Lower-pressure sessions can be more comfortable, reducing the likelihood of barotrauma (pressure-related injuries) to the ears and sinuses.
- Accessibility and Cost-Effectiveness: Lower-pressure HBOT chambers are often less complex and more affordable, potentially increasing accessibility for clinics and patients.
Clinical Implications and Future Directions
The promising results from studies on lower-pressure HBOT underscore the need for further research to establish standardized protocols. Clinicians should consider individual patient needs, and ongoing monitoring is essential to optimize outcomes.
Conclusion
Lower-pressure hyperbaric oxygen therapy represents a promising avenue for supporting nervous system and brain health. By enhancing neuroplasticity, improving cognitive function, and increasing cerebral blood flow, this therapeutic approach offers a potential tool for clinicians aiming to treat neurological conditions. As research progresses, HBOT may become an integral component of neurological therapy, providing patients with effective and safe treatment options.
