Hyperbaric Oxygen for COVID-19 Patients With Moderate to Severe Hypoxemia

Stopped early · Not applicable

Conditions studied: Covid19

In brief

Of the many treatments proposed for COVID-19, few directly address the severe hypoxia among COVID-19 patients. Interim results from our single-center, non-randomized clinical trial (NCT04332081) suggest that hyperbaric oxygen therapy may reduce inpatient mortality or the need for mechanical ventilation among COVID-19 patients by more than half. Hyperbaric oxygen therapy is delivered by increasing the atmospheric pressure surrounding a patient, which results in increased oxygen delivery to a patient's blood at a rate higher than any other available modality. It is already FDA-approved for several indications, including conditions with impaired gas exchange and severe infectious processes. Furthermore, several studies have found that hyperbaric oxygen therapy inhibits the production of proinflammatory cytokines, which may play a role in the pathophysiology of COVID-19. The goal of this proposal is to perform a multi-center, randomized controlled trial to evaluate the short-term and long-term efficacy of hyperbaric oxygen therapy for COVID-19 patients. This proposal will rigorously test whether hyperbaric oxygen therapy can reduce the substantial mortality and morbidity of this challenging disease.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age > 18 years
• Positive COVID 19 test or clear clinical diagnosis of COVID-19. Positive COVID-19 test will be confirmed based on a PCR or antigen test result or patient reported history. Clear clinical diagnosis of COVID-19 will be a combination of respiratory symptoms and clinical findings based on laboratory values and radiographs.
• Moderate to severe hypoxemia defined by a baseline supplemental oxygen requirement of 6 liters or higher (including high flow oxygenation devices) as measured within the 24 hours before enrollment

You may not qualify if…

• Pregnancy
• Untreated pneumothorax, which must be evaluated with a baseline chest radiograph or computerized tomography scan at least 72 hours prior to enrollment
• Presence of pneumomediastinum, pneumopericardium, significant subcutaneous emphysema, or pulmonary blebs, which should also be evaluated with a baseline chest radiograph prior to enrollment
• Current invasive mechanical ventilation
• Current non-invasive mechanical ventilation
• Any patient who will not be stable for transport to the hyperbaric chamber, in addition to any relative contraindications identified by the treating hyperbaric physician or inpatient hospital team (e.g., severely impaired cardiac output due to significant myocardial injury).
• Any patient without the capacity to provide informed consent
