The Estimated/Expected Peak Expiratory Flow (Peak Flow) quantifies asthma exacerbation severity. Calcs that help predict probability of a disease Diagnosis. Subcategory of 'Diagnosis' designed to be very sensitive Rule Out. Disease is diagnosed: prognosticate to guide treatment Prognosis. Numerical inputs and outputs Formula. 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.
How does this peak flow calculator work? This is a quick health tool that determines the estimated or predicted peak flow based on your data. You need to select your gender and input your age and height. The former can be put in either metric (cm) or English (inches) measurement. Apr 22, 1989 · Abstract. An earlier study of peak expiratory flow (PEF) in normal adults contained too few men aged over 55 and women aged over 65 for the regression equations to be used for prediction Cited by: 304.

"Personal best" measures should be used for the asthma treatment plan. Apr 22, 1989 · An earlier study of peak expiratory flow (PEF) in normal adults contained too few men aged over 55 and women aged over 65 for the regression equations to be used for prediction in older people. A subsequent study was therefore carried out on an additional 23 men and 29 women aged 55 or over who were lifelong non-smokers and satisfied the same strict criteria of normality that had been Cited by: 304.
