During this study, we noticed the patients' need for more precise information, which transmitted safety and reliability, since part of the success of this treatment is embedded in the technique. These people are eager to learn, without the opportunity to look for other sources of knowledge, except for our institution. On the other hand, we also found professionals with deficits in their academic background, who do not know the technique or are insecure about the best way to teach their patients, often choosing not to instruct them. It is the doctor's responsibility to teach them with patience, perseverance and confidence. In order to make it a reality in the Medical School of Botucatu, in 2002we proposed to give classes on the subject as well as to enable the students (interns) to adequately instruct their patients by performing the technique during the appointments.
In face of such results and, in agreement with the literature, we can conclude that doctors are potentially responsible for their patients' performance in the use of the inhalation technique (6,8,12,17).
