How it works – Three primary modes of virtual auscultation at home and in clinic
Live stream

Primary Care Provider with Patient to Specialist/Consultant
The primary care provider is with the patient and live streams auscultation sounds to eMurmur’s consulting provider, who hears and sees the sounds via eMurmur‘s browser-based web portal.
Plans: Telehealth Basic, Telehealth Single-User
Asynchronous
Primary Care Provider with Patient to Specialist/Consultant
The primary care provider is with the patient, stores the auscultation data in the secure eMurmur cloud, and requests remote consultation. The consulting expert reviews the case and provides feedback via the web portal.
Plans: Telehealth Single-User & Enterprise
Live stream
Direct-to-Patient
eMurmur includes a patient-facing interface that connects providers with patients at home. The patient at home self-navigates the stethoscope as per provider instructions. Heart and lung sounds are live streamed to the provider, who hears the high fidelity sounds via the web portal.
Plans: Telehealth Single-User & Enterprise
