| pubmed-article:8355540 | pubmed:abstractText | Aerosol inhalers constitute the most commonly used form of administration of medication by most of the patients with respiratory disease although incorrect usage is a demonstrated fact in many studies. A previous study demonstrated that, despite correct instruction by health care staff and the patients, 30% of the same use these inhalers incorrectly. In the present study, the efficacy of inhalation chambers (750 ml) and spacers (50 ml) versus the conventional inhaler was evaluated by quantification of bronchodilator response. | lld:pubmed |
