COPD (chronic obstructive pulmonary disease) is a leading cause of illness and mortality worldwide. According to WHO estimates, 65 million individuals suffer from moderate to severe COPD. COPD killed about 3 million people in 2005, accounting for 5% of all deaths worldwide, and it is expected to be the third greatest cause of death by 2030. Developing countries are rapidly changing. Socioeconomic development, industrialization, urbanization, changing age structures, and changing lifestyles have resulted in a growing burden of noncommunicable diseases (NCDs), like COPD, in the countries. India contributes a considerable and growing proportion of COPD mortality, which is considered to be among the highest in the world, with more than 64.7 estimated age-standardized death rates per 100,000 people in both sexes. Crude estimates suggest there are 50 million COPD patients in India. Among which the disease is very much noncommunicable in kids. Spirometers are breath analyzers or devices used for conducting spirometry tests for the diagnosis of respiratory issues like COPD & asthma. This project is to redesign the spirometer for kids of 5-10 years old to encourage them and test their lung function for the betterment of their lives.
