It continuously checks your pulse, breathing, and blood oxygen levels, and sends readings by Bluetooth to the nurse's station.

"We don't have to go into a room every hour or two, to check an oxygen level," Dr. Carmona adds.
Patients can also be safely discharged with the SafetyNet, to be monitored at home.
During this outbreak, that could free up precious beds for more seriously ill patients.
