Doctor's COVID-19 discovery could drive Apple Watch 6 sales
12

Today's New York Times has an interesting opinion piece written by an emergency room doctor by the name of Richard Levitan. The doctor believes that he has figured out a way to keep many patients off of the dreaded ventilator machine that does the breathing for them. 80% of those who are intubated and put on a ventilator don't survive.
The Apple Watch 6 could provide an early warning sign of COVID-19
By using a device called a pulse oximeter, people can track their oxygen saturation levels and when they drop below normal, it would be an early warning sign. He also said that anyone who tests positive should have a pulse oximeter as should those who tested negative but have symptoms such as a cough, chills, fatigue, and fever. And this is where the upcoming Apple Watch 6 comes in.

An example of a pulse oximeter used in a hospital
One of the new features rumored to be on the next generation of the world's most popular watch is a pulse oximeter. If we are still worrying about COVID-19 in the fall (as seems likely even if we aren't practicing social distancing by then), and the public starts monitoring their oxygen sat levels, demand for the Apple Watch 6 could get a big boost. Besides providing users with an early warning about COVID-19, the pulse oximeter can give someone an early warning about possible cardiac or respiratory arrest. A reading under 80% could also indicate that a heart or brain problem is imminent. Back in March, just as the coronavirus was about to lock down the entire world, "snippets" of code from an early version of iOS 14 revealed that the next Apple Watch will be equipped with a pulse oximeter.
The Apple Watch has been a big hit for Apple and its health-related features have saved some lives. The heart rate monitor has warned users when their heart was beating too fast, sending them to the ER where a life-threatening issue was discovered. Apple added an electrocardiogram (ECG) to the Apple Watch 4, and this feature monitors the user's heart rhythm looking for an abnormal heart rhythm that could be a sign of Atrial fibrillation or AFib. This is a condition that can lead to blood clots, stroke, and heart failure. Yes, the ECG has also saved lives.
If the Apple Watch 6 adds a pulse oximeter as expected, it could help generate huge demand for Apple's next smartwatch. Still, we do need to point out that pulse oximeters are available online for $40 to as high as $200. The advantage to having it on the Apple Watch is that you could get a reading wherever you are without having to carry the meter in your pocket everywhere you go.
