At present I am on 1000mg of Uniphyl 2 puffs of Aerobid and Serevent morning and evening. Iuse the peak flow meter at least once a day. My baseline is approx . 500 but start having problems below 400. The only time I have used a peak flow meter is at the doctors office.
Higher numbers mean the airway is more open and lower numbers mean it is more closed or tight.
If the peak flow is going down before you have trouble breathing, you can treat yourself early before you get into trouble. My computer locked and I had to reboot. I don't know if my question made it and was answered or not. A book I read said that you should try and stay within 90f your best with the use of meds. I find my son requires quite a bit of steroid to stay that well.
