Use of Hyperbaric Oxygen Therapy to Treat COVID-19 Patients With Respiratory Distress

Using the Monoplace Hyperbaric Oxygen Chambers we will be providing COVID- 19 positive patients with mild-to-moderate distress 100% oxygen at 2.0 ATA for 90 minutes on consecutive days for a total of up to 5 treatments. A comparison will be made using a historical cohort not receiving HBOT. Data will be collected to determine whether or not HBOT is of any benefit to COVID-19 positive patient with mild-to-moderate respiratory distress. Study Group: Provide 100% oxygen at 2.0 ATA for 90 minutes on consecutive days for a total of up to 5 treatment to COVID-19 patients meeting inclusion criteria Control Group: Any COVID-19 positive patient meeting study inclusion criteria that does not receive HBOT (historical) The control group is further defined as patients who were previously treated for COVID-19 at Morton Hospital that did not receive hyperbaric oxygen therapy. This will require accessing medical records to obtain patient information to establish the historical control data metric. Study outcome measures: * Time to normalize 02 requirement (ambient air pulse ox greater than or equal to 92% or ABG w/Pa02 greater than 60mmHG on air) * Mortality * Days free of invasive mechanical ventilation
