Tiny step back

Yesterday Marion was having some trouble breathing, and her blood oxygen content kept dropping below the 92-97% which is apparently optimal. She got a little oxygen cone put around her head. Apparently oxygen in the air is about 20% by volume, and they are putting her on 24% - 26% oxygen until she is breathing a little better. Not a huge difference, but it was quite a shock for Sarah and I when we saw this. Felt very overwhelmed by it last night, but I slept fine and feel better today.
