Why the study?
Home pulse oximetry has been proposed to identify silent hypoxemia in non-hospitalized COVID-19 patients, but important potential pitfalls and accuracy limitations may interfere with successful monitoring.
What are the potential pitfalls and practical guidance for using pulse oximetry to monitor patients with COVID-19 at home?

Urges caution with consumer-grade oximeters for COVID-19 home monitoring; leaves open need for rigorous validation trials.
What are the potential pitfalls and practical guidance for using pulse oximetry to monitor patients with COVID-19 at home?
Home pulse oximetry for COVID-19 monitoring requires careful patient counseling due to accuracy limitations and multiple sources of error, especially at saturations below 90%.
