The Latest: Do you need a pulse oximeter?

Dear Reader,

Never heard of a pulse oximeter? Don’t worry. The pandemic has introduced an entire glossary of terms people are learning now, including social distancing, antibody testing, and herd immunity.

A pulse oximeter is a small device for measuring blood oxygen levels that can be purchased at a pharmacy. Experts disagree over whether everyone should buy one. As Yasmin Tayag reports for the blog, they could be helpful for people who suspect they have Covid-19 but are not sure whether they should go to the hospital, or for those who have tested positive for Covid-19 but felt their symptoms were otherwise mild.

A Quick Coronavirus Vocab Lesson:

You’re probably hearing these terms a lot. Bookmark these definitions for the next time you’re feeling a little confused or overwhelmed by Covid-19 information.

Contact tracing: Finding people who came in contact with an infected person and letting them know they may have been exposed.

False positive: A conclusion that something is true when it is not, such as results indicating that a person has a disease when they don’t.

Cytokine storm: An over-response by the immune system, producing a lot of proteins called cytokines. Too many cytokines — a storm of them — can kill human lung cells and cause severe infection, difficulty breathing, and death.

R0: Pronounced “R naught,” the R0 is a “reproduction number” for a disease, signifying the average number of cases each infected person will cause.
