22 WACS outbound HL7 protocols Welch Allyn Connectivity Server
Outbound vital-sign tags and filters
WACS generates the vital-sign tags and filters described in this section.
By default, missing tags or tag errors cause the HL7 interface to reject the request or
query. If part of a message or reply is valid, WACS ignores or rejects the erroneous
portion and returns only the valid reply.
This setting is configurable in the WACS HL7 Manager pages (see the Welch Allyn
Connectivity Server directions for use).
Vital-sign tags
Vital-sign tags include vital sign name tags, unit tags and optional status fields.
