A new app, called Lungappen, was developed to help EMS students and providers recognize and study lung sounds.
Thomas Alvring, a nurse working for a Swedish EMS agency, developed the app in 2013, but it recently became available in English.
The app includes 20 patient cases, all with different respiratory issues and symptoms, which are outlined in a medical history.
The app can be downloaded for $4.99 through the App Store and for $4.83 through Google Play.
