About SAM4 Online
SAM4 Online is a professional auscultation training app for medical and nursing students, healthcare educators, and clinical skills trainers. Practice identifying heart, lung, bowel, and vascular sounds using a clinically validated library of over 100 simulated and real patient recordings – accessible on iOS, Android, and the web at sam4online.com.
Auscultation Library
The sound library is built on the Cardionics collection, developed and validated over decades of clinical use. It covers cardiac, pulmonary, bowel, and bruit conditions, pairing each sound with written descriptions, anatomical images, and echocardiogram videos for full clinical context.
Interactive virtual manikin
Practice stethoscope placement on a virtual male and female manikin with anatomically correct auscultation sites. Understand not just what a sound is, but exactly where to listen for it.
What you can do with SAM4 Online:
• Listen to 100+ cardiac, pulmonary, bowel, and bruit sounds
• Practice on a virtual manikin with correct anatomical auscultation points
• Study real patient recordings alongside simulated sounds
• Watch 12 echocardiogram videos and 24 clinical case videos
• Complete lessons, quizzes, case studies, and graded assessments
• Track your progress through a personal progress bar
• Join classes via QR code or link (institutional access)
• Access everything on mobile (iOS & Android) or in your browser
For educators and institutions
SAM4 Online gives teaching staff a complete classroom management toolkit: create lessons with curated Cardionics content or your own materials, import student groups, set assignments, and track individual and group progress in real time.
Hardware integration
SAM4 Online also acts as the control app for Cardionics auscultation simulators (SAM4, SAM4 Plus, Adult PAT4, Pediatric PAT4), enabling instructors to drive live simulation scenarios from their phone or tablet during hands-on training sessions.
Get started
Individual users can subscribe directly through the app. Institutions and educators can request a trial or purchase a license at 3bscientific.com.
