SafeNSound Document Integration via HL7 allows for documents to be sent via HL7 to the EMR.


The following document types in SafeNSound are supported:

  • Waveform Reports
  • Event History Reports
  • ICSC Reports

Document transfer interval can be set to the following:

  • Real-time
  • Upon Signing
  • Scheduled Task.

In most cases unsolicited HL7/ORU orders are required to be implemented on the EMR side so that each document can be attached to the patient record. 

The report format can be configured to be sent via file link or encapsulated PDF. Below are examples for both:


Example Message with Link to File
MSH|^~\&|SPACELABS||EPIC||2018||ORU^R01| |P^T|2.3||||||


Example Message via Encapsulated PDF
MSH|^~\&|SPACELABS||EPIC||2018||ORU^R01| |P^T|2.3||||||
