Hello,
Sometimes the level of spo2 in pulse oximeter drops to 88-90 for a few seconds when my parents who are both above 64 years old, do walking. (Both are co morbid, 1 with
diabetes & other had angioplasty 9 years ago, BP problem)
Is it normal for SPO2 to drop below normal level for 4-5 seconds after walking for 10 minutes?
