WACS outbound HL7 protocols
The WACS Outbound HL7 Vital-sign Observations module uses Java TM processes to read
patient data files from an Acuity System and forward the messages to a CIS server.
This chapter describes WACS protocols used in the Outbound HL7 Observations module.
The WACS protocols closely follow the data structure outlined in the Health Level Seven
Version 2.4 Messaging Standard.
