StethAid Lungs is an app to collect anonymised lung sounds of a study subject with suspected asthma. StethAid Lungs connects to the StethAid Bluetooth digital stethoscope and allows for streaming of data from the stethoscope. The lung sounds and the corresponding laboratory test results will be uploaded to a remote database for post-processing storage and reference.

Only the study subject’s age and gender is stored, no other PHI data is stored in the remote database.
