Abstract

Background: Metered dose inhalers (MDIs) are an affective modality of treatment for fast relief fromasthma flare-ups and other symptoms, and are often used by asthmatic athletes. It has got lots ofbenefits and some drawbacks depending on usage technique. With proper technique and trainingdrawbacks can be minimised. The objective of this study was to assess the metered dose inhalertechnique in patients with chronic lung disease at government hospitals of Rawalpindi. Methods: Across-sectional study was conducted in three government hospitals of Rawalpindi. The inhalationtechnique was assessed in six steps. Results: Clear evidence showed that only 24% patient couldperform all the steps correctly. Percentages of people that followed individual steps properly were:preparation (87.5%), exhalation (53.85%), lip closure (68.27%), inhalation (56.73%), breath-holding(27.88%) and puff interval (36.54%). Conclusion: This study showed that a number of patients ingovernment hospitals of Rawalpindi were unable to use metered-dose-inhaler properly and thereforeindicates the need to make people aware of this technique either by counselling or arranging seminars.KEYWORDS: chronic lung disease, asthma, metered-dose inhaler.
