ChoiceMMed Fingertip Pulse Oximeter

It works very well for what my needs are. Recently had heart surgery (5 bypass & valve replacement) It helps me to observed my heart rate & oxygen saturation during my home therapy & exercise. It also will help when I start outpatient therapy soon. Very afordable item for the information I need to know.

This is a very accurate and stable meter. By stable , I mean that the reading display doesn't fluctuate like the previous meter I had. My old one (which cost twice the price) would jump from ; example: say 72 to 91 then 80 to 70, all kinds of different display readings within seconds. I'm very pleased with this. I have been on oxygen for a year now and it's worth testing yourself to see how much your o2 level drops just from doing something simple like sitting ( 02 reading in the 90's ) to getting up and walking outside bending over once and walking back inside, sitting down and testing again ( 02 reading in the 70's ). Yes mine dropped from 93 to 77, just from that short 45 second walk. Sucks. I put my oxygen back on.
