Long COVID-19
According to the European Society of Cardiology, most COVID-19 sufferers fully recover, but after the initial illness approximately 10–20% of patients develop long COVID, also called post-COVID condition or syndrome. Symptoms include shortness of breath, fatigue, cough, chest pain, rapid or irregular heartbeats, body aches, rashes, loss of taste or smell, nausea, vomiting, diarrhea, headache, dizziness, insomnia, brain fog, depression and anxiety. Patients with post-COVID syndrome may also develop cardiac dysfunction and are at increased risk of a range of cardiovascular disorders.
How Does HBOT Help?
Several studies have looked into the potential benefits of hyperbaric oxygen therapy.
Conducted by researchers in Israel, the study looked at a group of patients whose cognitive symptoms of long COVID had lasted at least three months. Half underwent 40 sessions of HBOT over the course of two months. They received varying exposures of 100% oxygen over the course of 90 minutes, delivered via a mask, while in a hyperbaric chamber with twice the atmospheric pressure of sea level.
The other group of patients served as the control group. They also spent 40 sessions in the hyperbaric chamber, but breathed regular air, and at regular pressure. At the end of the study, the patients who underwent the genuine hyperbaric oxygen therapy reported a marked improvement in cognitive function. The therapy also had a positive effect on energy levels, sleep disruption and mood. The same results were not seen in the control group.
