Approximately 5–6% of patients diagnosed to have COVID-19 infection present with severe hypoxemia requiring invasive ventilation or non-invasive ventilation (NIV). Additional oxygen to patients on NIV can be given by nasal prong or by connecting oxygen tubing directly to the O2 pick-off port of the NIV mask or by connecting oxygen tubing to the single-limb circuit in between ventilator and patient. Dual oxygen therapy improves oxygenation in COVID-19 patients on NIV. This method may make the patient more comfortable, increase tolerance to NIV, increase the usefulness of NIV for moderate and severe COVID-19 acute respiratory distress syndrome (ARDS).
