For many individuals who develop symptoms of the
coronavirus, it's better to stay home than seek health care in person. But when you have a disease with so many unknowns, not having a nurse or doctor to monitor your condition can be nerve-wracking.
Pulse Oximeter
It's an electronic hand-held device that measures the saturation of oxygen carried in a person's red blood cells,
according to the American Lung Association. You usually attach it to your fingertip to get a reading.
"It calculates the oxygen level based on how red the blood is,"
Dr. Eric Cioe-Pena, an emergency medicine physician at Northwell Health in New York City, told TODAY. He added that it can detect changes in oxygen saturation "pretty readily."
"That's useful because in
COVID-19, one of the things we're seeing is people with severe pneumonias who come to the hospital have low oxygen levels," Cioe-Pena said. "One of the ways you can monitor high-risk patients is by asking to get a pulse oximeter they can use at home."
The device helps patients when they're feeling short of breath answer the question, "Is this something that's serious and I need to go to the hospital, or this something I can wait and see about?" Cioe-Pena explained. A reading below 90 merits contacting your doctor "sooner rather than later," he added.
Most of these devices cost around $20-$60.
