[Errors committed in using dosed aerosols in patients with obstructive lesions].
Errors committed in applying dosed aerosols in 100 patients were registered. Some criteria of correct technique being established, it was found out that more than 73% of the patients committed at least one error. The non-synchronization between inspiration and inhaler activation, considered as the most severe error, was met in 52% of cases, 14% of the patients being unable to do it even after repeated training. The importance of a refreshing instruction of patients, concerning the technique and advantages in using the expansion chambers and the conditioning as powders of inhaling drugs, are discussed.
