Not Normal: Usually a persons O2 sat should increase or stay same w mild-mod exercise. Do U have HX of smoking or asthma? Even so, UR fall in O2 sat is rather signif.Maybe sat meter not work prop when walking. Way to test: check UR pulse manually w wrist & watch w UR meter. If unsure a Cardiologist/Pulmon can place U on Treadmill & obtain O2 sat. UR finding suggest lung prob. I know not any other HX. See MD.
