question: My son is 2. He has been diagnosed with asthma. I took him to the dr Friday and they said he has bronchitis and a touch of pnuemonia. His breathing seems worse today. He is on an antibiotic, prednison, and dy G. Also we are doing albuterol breathing treatments every 3 hours. His O2 is between 90 and 93 when he is awake, but when he sleeps it drops to around 88-82. Is this normal?
