The Estimated/Expected Peak Expiratory Flow (Peak Flow) quantifies asthma exacerbation severity. Calc Function ; Calcs that help predict probability of a disease Diagnosis. Subcategory of 'Diagnosis' designed to be very sensitive Rule Out. Disease is diagnosed: prognosticate to . 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.
Guide to Asthma Appendix 2: Tables of normal peak flow values* * Note that the values shown are the average normal values for healthy persons of a given age and height. There will always be a range of normal values; not everyone can be expected to have exactly the same value. Men can have peak flow values as low as liters/minute less. The peak expiratory flow rate is the maximal rate that a person can exhale during a short maximal expiratory effort after a full inspiration. The Peak Expiratory Flow Prediction tool can calculate peak expiratory flow based on age and height.
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. Free Shipping on all Orders of $59 or more!
