O2 saturation

My 4 year daughter can only stand holding on,crawl and say three words.All tests-blood ,urine and chromosome are normal.Brain scan normal.She is a very happy,healthy but underweight and petite little girl.She is very afraid of sudden movements,does not like sand and cover her ears for sirten noises.O2 saturation level in 2006 were 64% and pO2 4.4 kpa.2009 O2 saturation were 66% and pO2 4.6 kpa.She never had any oxygen treatment.Can this have a influence on her mental growth and overall sutiation.What can be done to improve these levels,and if possible to get them up to 90+ will her brain devellopment increase?Thank you.

O2 saturation is very important and the levels you report are very low but they can vary depending on the situation in which they are measured.  This forum specializes in autism information from a clinical and educational perspective but not a medical one.  This question would be best directed towards a physician.  I suggest you discuss your concerns with your pediatrician.
