I have been advised by my respiratory therapist to get a SPO2 monitor. I have been searching for one that will work for me and not finding. At my therapy they could not use a finger probe but had to use an ear lobe probe because of cold hands. I try to be active in the outdoors, hiking, gardening, splitting wood, hunting, fishing, RVing and etc so the finger probe would not work for me. I have looked a smartwatches and fitbits since the monitor on the wrist/arm but what I am finding out they basically only monitor at night when sleeping and not available 24/7. Looking for advise for purchasing something I will use. Thank you. Lanny
