Understanding Long COVID

Long COVID, also known as Post-Acute Sequelae of SARS-CoV-2 (PASC), refers to a wide range of health problems that persist or develop weeks, months, or even years after an initial COVID-19 infection. The condition can affect anyone who has had COVID-19, regardless of the severity of their initial illness.

Research suggests that COVID-19 creates inflammation in lung tissue, preventing oxygen from reaching the bloodstream and resulting in organ hypoxia. Even after the acute infection resolves, this damage can persist, leading to chronic symptoms that significantly impact quality of life.

The increased pressure that a hyperbaric oxygen chamber produces oxygenates the fluid of the body directly, without relying on the blood supply. This relieves organ hypoxia much more quickly than conventional treatments, without stressing lung tissue. HBOT also reduces coagulation factors and pro-inflammatory cytokines, effectively addressing the increased clotting and cytokine storm patterns that COVID can create.

Common Long COVID Symptoms

If you or someone you know is experiencing these symptoms, seek medical attention. Early intervention is critical for many of these conditions.

Warning Signs

Debilitating fatigue and post-exertional malaise
Brain fog, difficulty concentrating, and memory problems
Shortness of breath and respiratory difficulties
Chest pain and heart palpitations
Joint and muscle pain
Sleep disturbances and insomnia
Headaches and dizziness
Loss of taste or smell
Anxiety, depression, and mood changes
Exercise intolerance

Why Long COVID Persists

Researchers have identified several mechanisms that may drive Long COVID symptoms. These include persistent viral reservoirs, chronic inflammation, micro-clotting in small blood vessels, autoimmune dysfunction, and mitochondrial damage leading to impaired cellular energy production.

COVID-19 can damage the endothelium (lining of blood vessels), leading to micro-clots that reduce blood flow and oxygen delivery to tissues throughout the body. This widespread tissue hypoxia can explain the multi-system nature of Long COVID symptoms.

The resulting oxidative stress and chronic inflammation create a self-perpetuating cycle that conventional treatments often fail to break, leaving patients struggling with symptoms long after their initial infection has cleared.

How HBOT Addresses Long COVID

Hyperbaric Oxygen Therapy directly targets the underlying pathophysiology of Long COVID. By delivering oxygen at increased atmospheric pressure, HBOT dramatically increases the amount of dissolved oxygen in blood plasma, reaching tissues that compromised circulation cannot adequately supply.

A landmark randomized controlled trial from Tel Aviv University demonstrated that HBOT led to significant improvements in cognitive function, energy levels, sleep quality, and psychiatric symptoms in Long COVID patients. Long-term follow-up confirmed these benefits were sustained over time.

Additional research from the Karolinska Institute has shown HBOT can improve cardiac function in Long COVID patients, specifically improving global longitudinal strain—a sensitive measure of heart performance. High levels of oxygen delivered during HBOT also act as a potent anti-inflammatory, addressing the inflammation in the lungs and other tissues that prevents normal oxygen exchange.

We have had a great deal of success treating patients with Long COVID at our facility, and current published studies strongly support our clinical experience.
