Mobile Kit to Diagnose Lung Diseases

BreatheDX is a mobile kit using smartphone technology and low-cost diagnostic sensors to diagnose pulmonary diseases.

BreatheDX is a low-cost mobile kit for diagnosing pulmonary diseases, such as asthma, COPD, and pneumonia, which are leading causes of death and disability worldwide. The platform is Android-based and consists of an electronic stethoscope and corresponding software that analyzes lung sounds and patient questionnaire data in order to provide diagnostic feedback to the physician or healthcare worker.
The diagnostic kit will cost less than $30 and can be deployed in communities without access to physicians, helping to screen patients and identify which patients need to travel to hospitals for follow-up testing.

Relevance of solution

Pulmonary diseases are an increasing global health burden and are responsible for more than 14% of deaths worldwide.1 These diseases are highly concentrated in the developing world, where patients do not have access to physicians, or physicians are untrained in the diagnosis of pulmonary disease, meaning that these illnesses are poorly understood and frequently misdiagnosed and underdiagnosed.2 3 BreatheDX addresses these issues by offering a low-cost, easy-to-use method for diagnosing pulmonary diseases so they can be properly treated and managed.

Triple Bottom Line


This solution sheds light on the increased risk of developing pulmonary diseases due to air pollution and unclean cooking stoves, which also have detrimental environmental impacts.


As more than one billion people suffer from chronic pulmonary diseases, diagnosing and properly managing these ailments can improve the quality of life for many.4


Diagnosing and managing pulmonary diseases can help to keep millions of people active in the workforce and reduce financial strains on healthcare systems.
