During PR it was noticed that sleep apnea may be an undiagnosed problem. I am due a blood test in a few days but in the meantime I tried an oximeter test just for my benefit.
I was horrified to see that on three occasions during one night my oxygen dropped way below 90% and on one occasion below 75%.During each occasion my pulse fell from a normal (for me) of around 85 - 90 bpm down to below 60 bpm.
Does anyone know if these results suggest that sleep apnea might be an issue?
