Reference population equations using peak expiratory flow meters: an over view

AI Salisu


Many formulae for predicting lung function values for Nigerians have been produced by a lot of investigators. The same principle but different statistical methods were adopted by different authors in generating these equations, hence the variability observed among these formulae. Most equations in current use are based on linear statistical models which are subject to change and they did not express the lower limit of normal. Therefore, in this study an attempt was made to give an over view of the currently available PEFR prediction equations that are in use in some of our out patient clinics in Nigeria. Some recommendations were also given on how to improve on future prediction formulae.
