*severe asthma* (chronic, daily or more attacks)



peak flow meter is used to ANS assess asthma severity at home
it measures the peak expiratory flow



asthmatic patients should use their peak flow meter how often? ANS daily to evaluate
manifestations and the amount of air that can be expelled out
