Health Level Seven Standard

The Welch Allyn HL7 Interface option closely follows the data structure outlined in the

Health Level Seven Version 2.4 Messaging Standard.

The following excerpt is taken from section 7.3 and section 7.4 of this standard:

“Many report headers (OBR) may be sent beneath each patient segment, with many

separate observation segments (OBX) beneath each OBR. Note segments (NTE) may be

inserted after any of the above segments. The note segment applies to the entity that

immediately precedes it, i.e., the patient if it follows the PID segment, the observation if it

follows the OBR segment, and the individual result if it follows the OBX segment.”

One result segment (OBX) is transmitted for each vitals component (such as Heart rate or

RR/BR).
