Raise your hand if you'd never heard of a pulse oximeter until a few weeks ago, when this New York Times op-ed piece freaked everyone out with talk of "the infection that's silently killing coronavirus patients." Now raise your hand if you scrambled to purchase a pulse oximeter and found them either significantly price-gouged or out of stock. (I ordered one from Walmart for $30; a few days later the price was up to $50.)

Good news: Pulse oximeters are in stock at some stores, and although you'll still pay more than you would have several weeks ago, there are decent deals. Whether or not you actually need one is a different story. I highly recommend reading Dale Smith's CNET report: Can pulse oximeters detect coronavirus? How they work and berita saham terbaru more.

Pay special attention to the section on accuracy. A pulse oximeter is a medical device that's meant to measure blood oxygen saturation levels and pulse rate. But do they all do that precisely? While there are tons of pulse oximeters on the market, not all are FDA-approved for checking your blood oxygen level. What's more, at least one study found that many of these over-the-counter pulse oximeters produce inaccurate oxygen level readings. Which raises the question: Should you even bother buying a pulse oximeter?

I'll leave that to you to decide. Here are three pulse oximeter options, all in stock at the time of this writing, at three different prices.  




Anself OLED Pulse Oximeter



Sold by Walmart but still coming from overseas





Anself Before the pandemic hit, you could find a pulse oximeter in your local drugstore for about this price. It's hard to say for sure how well this pulse oximeter works when it comes to measuring pulse rate and the oxygen saturation level in your blood (the product page currently shows no user ratings), but it looks similar to countless others -- just without the $50 price tag. Note that the seller here is not Walmart proper, but rather Joybuy, and that shipping is expected to take 10-15 days.



$20 at Walmart





Generic Digital Fingertip Pulse Oximeter



Just a few dollars more, but also a longer wait





Tomtop If you're not in a hurry, this model of pulse oximeter in stock ships from China in 10-20 business days -- meaning it could take as long as a month to arrive. Amusingly, you'll receive a random color: black, blue or teal, you don't get to choose. This pulse oximeter has no user ratings, and although it's shown to be "FDA registered," it's not FDA approved. It's a roll of the dice.

AccuMed CMS-50D1 Pulse Oximeter



Actually cleared by the FDA





AccuMed Although this finger pulse oximeter is sold out at Amazon (where it has a respectable 4.3-star average rating from nearly 1,900 buyers), you can get this popular model from AccuMed proper. And it's FDA-cleared, meaning it should work as advertised. As Smith wrote in the aforementioned report: "Note that there is a distinction between 'FDA-approved' and 'FDA-cleared,' with 'cleared' being the less rigorous of the two. That said, Class II medical devices like pulse oximeters are usually 'cleared' rather than 'approved.'"

What are your thoughts on these things? Is it worth having a pulse oximeter just in case? Or better to rely on medical-grade gear?
