[edit]

OK, I don't have a problem with the usage section provided its more encyclopedic in nature. The current rendition is instructional rather than descriptive. Something like: "The user exhales x times and takes the best three readings.." etc. --Hooperbloob 16:55, 6 June 2006 (UTC)[reply]

Usage section

[edit]

I've removed the Usage section entirely as it violatesWp:not#Wikipedia_is_not_an_indiscriminate_collection_of_information point 8. Here is the text I removed, if it can be rewritten into something encylopedic and without instruction, feel free to do so.

"The best of 3 readings is used as the recorded value of the Peak Expiratory Flow Rate. It may be plotted out on graph paper charts together with a record of symptoms.[1]

  1. Make sure the device reads zero or is at base level.
  2. Stand up if possible, otherwise sitting upright.
  3. Take as deep a breath as possible (but not through the meter).
  4. Place the meter in ones mouth. Close the lips tightly around the mouthpiece.
  5. Blow out as hard and as fast as possible (one to two seconds) without coughing, spitting or letting the tongue block the mouthpiece.
  6. The best of three recordings is used.

Users can record their peak flow before and 30 minutes after using the rescue inhaler. If their medicine is working an improvement should be seen in the peak flow reading." --Xyzzyplugh 14:29, 31 July 2006 (UTC)[reply]

A version of this article with the how-to sections intact has been transwikied to b:Transwiki:Peak flow meter. --SB_Johnny | talk 15:51, 3 September 2006 (UTC)[reply]

Move to Peak expiratory flow

Peak flow meter → Peak expiratory flow — The concept of peak expiratory flow is the main subject of the text - the peak flow meter is just the tool to measure it. Clearly, the Measurement section is not about how to measure the tool, but the peak flow itself. Most incoming links also refer to the concept, not its measuring tool. The target peak expiratory flow is more commonly used than peak expiratory flow rate. Mikael Häggström (talk) 06:35, 4 October 2010 (UTC)[reply]

Calibration of peak expiratory flow meters?

[edit]

The article states, "It is important to use the same peak flow meter every time." Assuming that one does not swap between an old scale and a new scale meter, this statement still suggests that there is no standard procedure for calibration of peak flow meters! Given that the scale is glued on to the body of the device, it would seem that there is ample room for calibration error during manufacture. Does anyone know whether there is an industry standard for calibrating these devices? And is there a traceable means for measurement calibration? DFH (talk) 18:23, 27 November 2010 (UTC)[reply]

Asthmatic but off the chart

[edit]

I've been asthmatic for many years and now in my 30's (175cm). I can frequently blow over 750 on a peak flow meter which is off the top off most devices and charts. Even when it's poorly controlled and feel SOB I hit 650+. Over the years, plenty of times with moderate-severe attack and barely able to make a whimper (eg. <200L/min; not taking preventer) and never a panic, never an ambulance, never a hospital. Just sit down and push through it with slow breathes (exercise induced). --tygrus (talk) 02:34, 26 July 2012 (UTC)[reply]

I'm also like that my peak flow is off the charts at over 1000 with a inspiratory capacity of 4500 in my mid 20's 175cm. When my asthma is bad I drop down to around to 600 and 2000 inspiratory capacity. Doctors won't help me because I'm still in "normal" range, last time looked having only running at 45% capacity of anything was very bad... — Preceding unsigned comment added by 147.226.211.221 (talk) 17:53, 14 March 2013 (UTC)[reply]

difference between maximal respiratory flow, and peak expiratoyr flow?

[edit]

This difference has been included in the article spirometry, in the article image, but not defined. Are they the same thing, or not? Some detail has been gone into in the article, but just some content about how they "theoretically" should be the same. So is one theoretical, and the other is pragmatic, or what? 129.180.1.214 (talk) 01:57, 11 June 2013 (UTC)[reply]
