I managed to get a copy of my spiro results the other day and was surprised by the reading I blew post neb.. Managed 621. Anyway since starting my PF diary the best I have managed is 570. Would I be right in thinking that it's unrealistic to expect to get as good as 620 normally/when having good days etc..? I mean post nebuliser is 'not normal' right?
On an aside, would a non asthmatic have any improvement in PF post neb?
