The highest levels for forced vital capacity (FVC), forced expiratory volume in one second (FEV1), maximal midexpiratory flow (MMEF), peak expiratory flow (PEF), and maximal expiratory flow at 75%, 50%, and 25% of the FVC (MEF75, MEF50, and MEF25 respectively) were taken independently from the three curves.
The enhancement in PEF, MEF75, and MEF50, was around 12% and that of MEF25 was 17%.
Although the mean value of MEF25 among smokers was normal, increase in this value of PFT due to salbutamol administration was more than other values of PFT.
