Thanks, Celia! I do monitor my oxygen. It has always read in the high 90s; today, also, when I was experiencing shortness of breath, it read 98. But I will mention this to both my PCP and home-health nurse, especially if it persists tomorrow. Rest assured, after struggling with sepsis for so many months, I won't take this lightly. Again, thank you for your post! And I will let you know how I fare in the coming days. –Ray (@ray666)
