Hyperbaric Oxygen Therapy for Long COVID: Latest 2025 Research and Treatment Options in Northern California

If you're struggling with persistent symptoms months after your COVID-19 infection, you're not alone. Long COVID affects an estimated 10-30% of COVID survivors, leaving many searching for effective long COVID treatment options. Recent research shows that hyperbaric oxygen therapy treatment for long COVID may offer the relief you've been seeking.
At NorCal HBO, we've witnessed how hyperbaric oxygen therapy (HBOT) is transforming lives for long COVID patients across Northern California and the nation. This article explores the latest scientific evidence and why our NorCal long COVID treatment approach delivers remarkable results for patients dealing with brain fog, chronic fatigue, and other debilitating symptoms.
Understanding Long COVID Symptoms
Long COVID encompasses persistent symptoms that can last months or years after initial infection:
Persistent fatigue and exhaustion
"Brain fog" and cognitive difficulties
Shortness of breath and exercise intolerance
Sleep disturbances and joint pain
Anxiety, depression, and heart palpitations
These symptoms aren't just inconvenient—they can be life-altering, preventing patients from returning to normal activities.
Recent Research on HBOT for Long COVID
Recent clinical research demonstrates that HBOT provides significant improvement in patients with long COVID across multiple symptom categories. Published studies, including case series and randomized trials, demonstrate that Hyperbaric Oxygen Therapy (HBO) provided significant improvement in patients with long COVID, according to a clinical review published in Frontiers in Medicine.
The most comprehensive data comes from a prospective registry that tracked long COVID patients undergoing HBOT, with patient-reported outcome measures collected at baseline, after treatment, at 3-month and 1-year follow up. This registry study was published in Scientific Reports in early 2025.
How HBOT Works
Hyperbaric oxygen therapy delivers 100% oxygen under increased atmospheric pressure (typically 2.0-2.4 times normal), creating therapeutic effects that target long COVID's underlying mechanisms:
Enhanced Oxygen Delivery: Forces oxygen into compromised tissues
Neuroplasticity Induction: Stimulates new neural connections, reversing cognitive impairments
Anti-inflammatory Effects: Reduces systemic inflammation central to long COVID
Improved Circulation: Enhances blood flow to address fatigue and other symptoms
Clinical Results: What Studies Show
A randomized, sham-control, double blind trial evaluated the effect of hyperbaric oxygen therapy (HBOT) on post-COVID-19 patients with ongoing symptoms for at least 3 months after confirmed infection. Seventy-three patients were randomized to receive daily 40 session of HBOT (n = 37) or sham (n = 36), published in Scientific Reports.
The study showed significant improvements in:
Cognitive Function: Executive function and attention improved following HBOT
Fatigue Levels: Significant improvements in cognitive, psychiatric, fatigue, sleep, and pain symptoms among long COVID patients who underwent hyperbaric oxygen therapy
Sleep and Pain: Documented improvements in sleep quality and pain management
Quality of Life: Overall improvements in patient-reported outcomes
A case series of 10 patients treated with HBOT yielded statistically significant improvements in fatigue, global cognition, executive function, attention, information processing speed, and verbal function. No adverse effects of HBO on these patients were noted.
Most importantly, long term outcomes studies document that these benefits persist after treatment has been completed, providing lasting relief rather than temporary symptom management.
Treatment Protocol at NorCal HBO
Our evidence-based long COVID treatment protocol is based on successful clinical trials:
Sessions: 90 minutes per treatment
Pressure: 2.0-2.4 atmospheres absolute, depending on patient tolerance
Schedule: Daily sessions (five days per week) for optimal results
Total Treatments: At least 40 sessions daily at 2 ATA is the scientifically proven treatment protocol
Each treatment plan is customized based on individual symptom profiles, severity of cognitive impairment, and personal health history.
Patient Success Stories
Sarah, Santa Clara Teacher: "After 18 months of brain fog and fatigue, HBOT gave me my life back. The mental cloudiness is gone, and I once again have energy for evening activities with my family."
Mark, San Francisco Cyclist: “Covid hit me hard. I couldn't climb stairs before treatment. Now I'm back on my bike and performing better than before COVID. The crushing fatigue is completely gone.”
In fact, we have treated several physicians with Post-Covid symptoms, all of whom have expressed gratitude for our help in getting them back to pre-Covid performance.
