Variability of the perception of dyspnea in healthy subjects assessed through inspiratory resistive loading.

Objective: Few studies have evaluated the variability of the perception of dyspnea in healthy subjects. The objective of this study was to evaluate the variability of the perception of dyspnea in healthy subjects during breathing against increasing inspiratory resistive loads, as well as to assess the association between the level of perception of dyspnea and the level of physical activity.

Methods: This was a cross-sectional study involving healthy individuals 16 years of age or older.

Repeatability of the evaluation of perception of dyspnea in normal subjects assessed through inspiratory resistive loads.

Purpose: Study the repeatability of the evaluation of the perception of dyspnea using an inspiratory resistive loading system in healthy subjects.

Methods: We designed a cross sectional study conducted in individuals aged 18 years and older. Perception of dyspnea was assessed using an inspiratory resistive load system.

Impact of a short-term educational intervention on adherence to asthma treatment and on asthma control.

Objective: To evaluate the effect of a short-term individualized education program on adherence to asthma treatment, inhalation techniques, and asthma control.

Methods: A prospective study involving patients aged 14 years or older, with a confirmed diagnosis of asthma and recruited from the asthma outpatient clinic of a university hospital in the city of Porto Alegre, Brazil. The study was conducted in two phases (before and after the educational intervention).
