Dual Oxygen Therapy in COVID-19 Patient: A Method to Improve Oxygenation.

Approximately 5-6% of patients diagnosed to have COVID-19 infection present with severe hypoxemia requiring invasive ventilation or noninvasive 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).
