ER Doctor: Pulse Oximeters Detect Oxygen Deprivation Earlier from COVID-19, Help Avoid Ventilators

We speak with Dr. Richard Levitan, an emergency physician based in Littleton, New Hampshire, who volunteered at Bellevue Hospital in Manhattan for 10 days at the height of the COVID-19 surge in April. Based on what he saw, he argues patients should be going to hospitals sooner and that medical professionals could use a small device you clip on your fingertip, called a pulse oximeter, to help detect the virus earlier by revealing oxygenation problems and elevated heart rates. A pulse oximeter is just a measure of identifying how well the lungs are working, and, I believe, can be basically an early warning system in terms of patients to know who has COVID pneumonia," says Dr. Levitan.
