Device Interface - Welch Allyn CardioPerfect

This page describes the interface between Enterprise Health (EH) and the Welch Allyn EKG and Spirometry Monitoring system known as CardioPerfect.


Within EH a user navigates to a page in the patients chart or opens an order section in the encounter that is configured with MIE’s layout for interfacing to CardioPerfect. The tab launches an ActiveX control that interfaces to CardioPerfect. If the patient is not registered in CardioPerfect, EH will create the patient. It will transfer/update:

  • MR number (Which MR number is controlled by configuration in the layout)
  • Name
  • Address (Addr1, Addr2, City, State, Zip)
  • DOB
  • Most recent height
  • Most recent weight

Then the end user is presented CardioPerfect to conduct the test. After the the user completes their session with the patient in CardioPerfect:

  • If the FileLink program has been correctly configured, a TIFF image and XML file will now exist in the user-configured directory.
  • EKG
    • The user chooses that TIFF image from the VidCap control.
    • The user clicks the “Get Interpretation” button to pull the automatically generated interpretation into a text area.
    • The user chooses Normal / Abnormal.
    • The user clicks the Upload button in EH to create a document from the TIFF and an observation from the interpretation. The normal/abnormal value is stored as the flag on the interpretation observation.
  • Spirometry
    • The user chooses the TIFF image and the XML File
    • The user clicks the “Upload File” button

        • Image Type = TIF

        • Check all boxes under Image and XML
