Abstract
Conclusion: Even though the values measured by both instruments vary, still the peak flow meters can still be advised for measuring PEFR in healthy individuals and daily monitoring of symptoms in asthma and chronic obstructive pulmonary disease patients as these are not very expensive, and procedure can be easily performed by all and repeated tests give almost same results. First time in 1942 Hardon said that PEFR can be used as a tool to determine the lung function that is ventilation, but only after few years, it was included as a part of regular spirometry. [2] The digital spirometers measure PEFR along with various other lung function parameters such as forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), breath holding time (BHT), and maximum voluntary ventilation (MVV). The volume of air respired can be measured by spirometry, it also records time taken and speed of air. [...]it is one of the most important tests to determine the functioning of lungs.
