INTRODUCTION. The main factor for the correct administration of inhaled medication is the technique in the use of the device to ensure that the drug reaches the airway and achieve clinical improvement. OBJECTIVES. Determine the percentage of patients who do not perform a correct technique, define the most frequent error, the age group with the greatest number of errors and establish if there is an association between exacerbations in the previous year and an adequate technique. MATERIALS AND METHODS. An observational, cross-sectional study that evaluated the technique of using the pressurized metered dose inhaler (pDMI) in 64 patients over 18 years of age with a definitive diagnosis of a chronic lung disease that used as a treatment a pressurized metered dose inhaler by direct technique, attended in the External Consultation of the Pulmonology Service of the General Hospital of the South of the Ecuadorian Social Security Institute, the evaluation was carried out according to the steps described in the SEPAR-ALAT Consensus on inhaled therapy. RESULTS. 85,0% (64) presented errors while using the inhaler, the most frequent error was not exhaling until the lungs were emptied, those over 65 presented 4 errors, those who did not exacerbate in the previous year had 2 errors and it was shown that when performing a correct inhalation technique, the number of exacerbations decreased OR 0.56 IC (-0.82; 1.95). CONCLUSION. The high percentage of patients who did not perform an appropriate inhalation technique in the use of the device was demonstrated, hence the importance of prior training, to achieve effective therapy.
