The change in scale for peak flow meters will result in PEF readings that are different, depending on whether the individual has used a Wright scale meter, or the new EU scale meter. Sometimes, it is useful for health professionals to have a guide as to what peak flow could be expected from each individual, if they didn't have asthma.
Useful in patients who do not know their baseline peak expiratory flow rate (peak flow). Comparison of a patient’s current peak flow to a known or expected personal best is only one aspect of the evaluation of a child with an acute asthma exacerbation.
Peak flow meters come in two ranges to measure the air pushed out of your lungs. A low-range peak flow meter is for small children, and a standard-range peak flow meter is for older children, teenagers and adults. An adult has much larger airways than a child and needs the larger range. There are several types of peak flow meters available.
A peak flow meter may be used to check your asthma like a blood pressure cuff is used to check high blood pressure. In order to help your physician provide the most appropriate treatment, proper use of the SpiroFlow is essential.
