Above normal Peak Flow?

posted 32 months ago by dawn

Since being diagnosed with Asthma (11/2009) my normal/best Peak Flows have been 450 to 500.   Today I easily hit 650.  I'm excited but wonder what, if anything, it means.  I've been on the same controller for a year now.  Is this normal to have mediocre readings  for 1 year or more then spike high?    In the last few weeks I noticed I've been doing more things that I haven't done unless careful thought and planning were involved......

Is this part of the program?

    Did you by any chance take a bronchodilator before this test?  Those will spike readings.

    Either way, this is good!  

    If I were you, what i'd do is if your PFs remain in this range, you can likely change your personal best.  If they don't increase, don't worry about it and just take this as a random outlier.  You might mention this to your asthma care provider at your next appointment and they'll likely be able to instruct you further on this.

    I find that my peak flow will be stupidly high (700+, when my p.b. is 580) if I accidentally cough a bit when I take a reading. Is that a possibility for you?

    On the other hand, about a week or so after my doctor switched me on to my current regime, my lungs did the same thing: They had an "aha!" moment and my personal best peak flow jumped from 320 (after I started taking my peak flows again - I had a goofus asthmatic phase in my teenage years when I though that having a break at mild intermittent asthma meant that I "grew out of it" and didn't have to worry) to 500, so it could be that your lungs are doing something of the sort.

    My respirologist told me that the peak flow metre should not be considered "the bible"....that even if it reads my pb, and I'm symptomatic...believe the symptoms, not the metre.
