Studies to Determine Whether Oxygen Sensing is Impaired in Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Infected Patients

In this phase of the study, each subject will be asked to hold their breath for up to 60 seconds or until they can longer hold it. While they are holding their breath, subjects will be hooked up to a monitor that will measure their Peripheral oxygen saturation (SpO2) respiratory rate (RR), and heart rate (HR).

In this phase of the study, each subject will be asked to walk for 6 minutes in their hospital room or hallway. Their rate of perceived exertion will be measured while also hooked up to a monitor that will measure their Peripheral oxygen saturation (SpO2) respiratory rate (RR), and heart rate (HR).
