Garmin’s Wrist Pulse Ox: Reduced Accuracy

Other athletic pilots agree that it sure would be convenient if there was one device that did it all, and since we covered pulse oximeters in the September 2017 issue of Aviation Consumer, Garmin released the D2 Delta PX aviator watch. It has an integrated pulse oximeter and a variety of other biometrics capabilities. I've been using it for close to a year and found that while it's not the perfect solution, it comes close, with limitations.

SPO2 on Garmin’s D2 Delta PX is displayed in both oxygen saturation percentage and as a color gauge.

Compared to other portable gadgets, cockpit health monitors have been surprisingly slow to evolve. As an aging athlete, I obsess about heart rate, pulse and hydration, and add blood oxygen saturation to that list in the airplane.
