In addition to face masks, you definitely should stock up on hand sanitizer. Purell is actually available right now on Amazon, shocking though it may be, and Suave hand sanitizer is the second-most popular brand we’ve been covering lately and unlike Purell, prices aren’t too inflated.

There obviously a few more things you need like hand soap and paper towels, but there’s one more thing that you really need to make sure you have on hand.

What’s this additional item that you need so desperately? It’s called a pulse oximeter, and it’s a tiny little gadget that clips onto the end of your finger and reads your blood oxygen saturation. Why is it so important? Because it can alert you to a possible coronavirus infection long before anything else that’s readily available — and that includes a thermometer. Many people who have COVID-19 don’t ever get a fever, as we’ve seen in several studies.

COVID-19 attacks many parts of the body but it typically wreaks the most havoc on your lungs. Long before any other symptoms present, a COVID-19 infection can hinder the lungs’ ability to draw oxygen from the air. This causes blood oxygen levels to drop, and that’s why monitoring your blood oxygen level can be crucial in catching a possible coronavirus infection as early as possible. One coronavirus survivor who has been battling COVID-19 recently reminded everyone of this on Twitter:

In a healthy person, blood oxygen saturation should be anywhere between 95% and 100%. According to the Mayo Clinic, anything below 90% is considered unhealthy. In coronavirus patients, blood oxygen saturation as low as 50% has been observed. The Zacurate Pro Series 500DL Fingertip Pulse Oximeter is the best-selling model on Amazon and it only costs $29.95, so there’s really no reason not to get one. It only takes a few seconds to take a reading so you can do it each day, and then reach out to your doctor if you find any cause for concern.
