TI  - Peak expiratory flow associated with change in positioning of the instrument: 
      comparison of five peak flow meters.
PG  - 291-4
AB  - To determine if peak expiratory flow (PEF) is altered by incorrect positioning of 
      five peak flow meters (PFMs), 16 adults with clinically stable persistent asthma 
      were evaluated. After inhaling two puffs of albuterol via AeroChamber, patients 
      were instructed over the next 15 min in correct PFM technique and two incorrect 
      techniques (PFM angled 20 degrees left in mouth and PFM pointed 20 degrees 
      downward as patient leaned forward with maximal exhalation). Order of use of five 
      peak flow meters and correct vs. incorrect techniques were random. Although mean 
      values generally indicated no clinically meaningful effect of positioning of the 
      PFM, inaccurate PEFs were recorded for several subjects with both incorrect 
      methods and all PFMs.
