Research Objective

To explore the potential therapeutic use of hyperbaric oxygen (HBO) treatment for COVID-19, particularly in advanced stages and for progressive hypoxemia.

Methodology

This is a letter to the editor, discussing existing research and potential applications of hyperbaric oxygen therapy (HBOT) for COVID-19. It references several studies to support its claims.

Discussion

The text discusses the mechanism by which HBOT might benefit COVID-19 patients, focusing on its ability to deliver higher concentrations of oxygen to tissues, which could counteract the lung damage caused by the virus. It also acknowledges concerns about attributing improvements solely to HBOT and notes contraindications for its use in certain COVID-19 patients.

Key Findings

Hyperbaric oxygen treatment may be a feasible option for treating advanced stages of COVID-19 by reducing inflammation, promoting healing, decreasing edema, and increasing blood flow. It can also aid in the recovery of immunological and circulatory processes and stress levels. Some studies have reported improved survival in COVID-19 patients treated with HBOT.

Conclusion

While the therapeutic use of HBO2 in COVID-19 has been modest, interest is growing, and it shows promise as a potential treatment, especially for severe cases and hypoxemia, by improving oxygen saturation and aiding in recovery processes.

Fact Check

1. COVID-19 emergence date: The text states COVID-19 emerged in late December 2019. This is consistent with the timeline of the pandemic's initial identification.
2. Oxygen delivery in HBOT: The text claims that at high atmospheric pressure, oxygen inhalation absorbs fifteen times more oxygen into the plasma than the typical amount. This is a common explanation for HBOT's efficacy.
3. COVID-19 variants: The text lists several variants: alpha, beta, gamma, delta, and epsilon. These are recognized SARS-CoV-2 variants of concern.
