Wish Apple would explain why it can’t get an exceptional approval from the FDA activate the latent blood saturation odometer that is built into every Watch it has ever sold.
High quality pulseoximetry units are sold out and the web is swimming with units of questionable performance and provenance.
Health experts are on record that an essential item which could reduce fatalities due to folks not going into the ER or arriving too late would be simple blood oxygenation monitoring which could alert the wearer to their lung performance sliding toward the critical zone.
I’ve sent both tweets and email to too Apple management hoping to hear something about why this feature is not made available in this crisis.
Not everyone will be able to afford the Watch 6 rumored to be coming w this feature.
If backward activation of an effective predictor is possible, Apple could do a huge favor to humanity as there are over 100 million of these things in circulation now.
Maybe someone at MacRumors.com can ask Apple to respond to this idea. The rest of us could tweet it to @tim_cook and @pschiller.
To my knowledge (35 years as a Biomedical Engineering Tech), no current AW has the capability of doing pulse oximetry. It can do plethysmography (pulse rate) just fine but it does not have the LEDs and sensors to do oximetry. The AW6 will have them.
