Hi Lizzie,

Sorry for the delay but I have been feeling MUCH better. I realized that rest was part of the main problem I was having. But to answer your question, I do have an oximeter, spo 5500, and fortunately my sats haven't dropped under 90 in over a year. This is probably because I haven't been working for that long and the only exhausting activity I do is moderate excersising.

As for why it dips so fast is the same reason why others with MG can't walk up a flight of stairs, they're just too weak. I have noticed that without oxygen my sats drop from 100 to 96 when I walk 50 feet, but with oxygen the lowest it goes is 98.

Thanks for your concern,

Steph
