How to Build an AI-Powered Stethoscope System for Healthcare Professionals
To build an AI-powered stethoscope system for healthcare professionals, we developed a secure diagnostic platform that combines high-precision audio capture with AI-driven signal analysis to support faster, more accurate clinical decision-making. The system enables doctors and nurses to access real-time insights, securely stores patient health data, and ensures compliance across diverse care environments.
Designed with multi-role access and centralized administration, the solution strengthens collaboration, enhances patient-centered care, and improves operational efficiency across healthcare settings.
Technical stack includes:
The history
The client aimed to create an AI-powered stethoscope to modernize diagnostics. This telehealth tool uses AI to analyze heart and lung sounds, enabling early disease detection. We began with a POC, showcasing the potential of AI in stethoscope data interpretation for accurate diagnostics.
The team
We started this project in 2021, with development in 2022, and resumed in 2024 after a two-year pause for FDA certification. Our team, including backend, frontend, mobile, DevOps, UI/UX, QA, data scientists, and project managers, collaborated with hardware experts to build an end-to-end solution.
Ardas role
We developed a software suite and AI model for the stethoscope device, including a mobile app for AI analysis, a web app for secure data management, and a scalable cloud backend. Our solution supports 10,000 users, ensuring high performance, reliability, and seamless integration with the hardware.
Challenges
Meeting FDA, HIPAA, GDPR, and HL7 FHIR standards was critical. Data security relied on anonymization and end-to-end encryption. We tackled noise filtering with advanced AI, achieving 85% diagnostic accuracy while ensuring scalability, 99.9% uptime, and offline functionality for remote areas.
