I am so sorry this answer is this late,
I posted an answer to this from a mobile device the day you sent the question, but it did not come through. I hope your daughter is feeling better by now. If there are any other questions please post and I will get back to you as soon as possible.

Hi
Oxygen levels really should be in their high 90's. A reading of 94% is what is needed. She will require oxygen to keep her saturations high. Make sure they are above 94%. Without knowing the age of your daughter I can not comment on the heart rate. When a child is having respiratory problems the heart needs to work harder to get the oxygen around the body...hence a higher pulse rate.
Hope she makes a speedy recovery.
