Green means your peak flow rate is 80%-100% of normal. Yellow means it is between 50-80%. Red means it is less than 50%. If you are using a peak flow meter, read your peak flow rate on a scale with three different zones. The highest number that you get will be the peak flow...
(see obstructive inFigure 1b) is more useful in practice, because the interindividual flow variability in a normal population is so large, althoughMEFVcurves are very reproducible within an individual. If the flow–volume ratio is borderline forairflow obstruction(FEV1/FVC >65% or <75%), ...

There are UK guidelines for the “normal” values which you can use to compare against the values your patient is able to achieve. This station therefore tests several examination skills, firstly your knowledge of the underlying condition being monitored, how to use a peak flow meter an...
TruZone Peak Flow Meter 峰值流量计Trudell Medical International Take control of your asthma. Many people underestimate the severity of their asthma. Because symptoms can come on slowly, you may not notice increasing limitations on physical activities — limitations that may be accepted as “normal”...
Preproduction and current models of the miniature Wright peak flow meter have been compared with the standard Wright peak flow meter on normal and abnormal subjects. Early problems in production appear to have been overcome, and the current model agrees to within 3% with the standard peak flow ...
One barrier to diagnosis is the limited availability of spirometry testing, but in adults at risk for COPD, a normal pre-bronchodilator (pre-BD) peak expiratory flow (PEF) may rule out clinically significant COPD. Objective: To identify post-BD airway obstruction using data from 13 708 ...
Pre-market evaluation/validation: Spirometry systems are evaluated using computer-driven mechanical syringes or other equivalent test systems to test the range of exhalations that are normal to find in the tested population. It should be noted that it is not up to laboratories to test the... ...
