OBJECTIVE	Inhalation therapy is the main treatment for asthma and its adequate use has been a factor responsible for disease control ; therefore , the aim of the study was to determine whether a digital media tool , which features portability on mobile phones , modifies the assimilation of the inhalation technique .
METHODS	A total of 66 professionals working in the health care area with the pediatric population were selected .
METHODS	They were submitted to a pre-test on their knowledge of inhalation therapy .
METHODS	The professionals were randomized into two groups ( A and B ) .
METHODS	Group A received a media application on their mobile phones showing the steps of inhalation therapy , while group B received the same information in written form only .
METHODS	A post-test was applied after 15 days .
METHODS	The results ( pre - and post - ) were analyzed by two pediatric pulmonologists .
RESULTS	Of the 66 professionals , 87.9 % were females .
RESULTS	Of a total possible score of ten , the mean score obtained in the pre-test was 5.3 3 , and in the second test , 7.5 2 ( p < 0.000 ) .
RESULTS	There were no significant differences when comparing the two groups ( p = 0.726 ) .
RESULTS	The nurses had the lowest mean scores in the initial test ( 2.3 2 ) ; however , they were the group that learned the most with the intervention , showing similar means to those of other groups in the second test ( 6.1 3 ) .
CONCLUSIONS	There was significant improvement in knowledge about inhalation therapy in all professional categories using both methods , demonstrating that education , when available to professionals , positively modifies medical practice .
