Problem addressed

Listening to lung and heart sounds using a stethoscope (auscultation) is commonly required in a standard medical consutlation but cannot be achieved in the current telemedicine setting. Vitogram® bridges this gap by enabling doctors to perform remote auscultation on patient's smartphone.

Innovation
  • D²4H's AI technology, namely ausculto®, enables real-time detection, denoising, and assessment of heart and lung sounds on standard smartphone devices.
  • The accurate real-time performance of this system enables widespread usage of this technology in telemedicine and long-term health monitoring.
  • The collected data are timestamped and can be stored on the smartphone or the cloud. Before or during a telehealth session with a doctor, the patient can share any range of data with the doctor through a secure web portal.
Key impact
  • Cost-effective and accessible technology that can be used in conjunction with existing telemedicine or health monitoring platforms
  • Allows doctors to access essential health data for clinical decision-making in a telemedicine setting
  • A highly secure personal health record management system
  • An-easy-to-use smart dashboard to support telehealth consultations
