This is used where you want to distinguish periodic,aperiodic etc. Metric Category also provides distinction between manual and automatic.MDS Status describes states - disconnected, configuring, operating, terminating,disassociated, reconfiguring. Relates to general question of alerts and events. Value,Units, and Observation Status will be mapped to the OBX-17 or OBX-8.MDS MODEL is used to provide device vendor/model and shall be mapped at the MDSlevel in the OBX with the value described by OBX-3.MDS DEVICE TYPE is used to describe the type of the PCD such as monitor, ventilator,infusion pump…and shall be mapped at the MDS level in the OBX with the valuedescribed by OBX-3.For PCDs with complex operation states such as an infusion pump with a set of states like"Stopped", "Infusing Primary", "Infusing Secondary", "Bolus", etc.. or a ventilator withstates "Standby", "Ventilating", etc. the Device Operational Status Enumeration Object ismapped to OBX-3.A.3 Mapping 11073 Value Types to HL7 OBX-2.There is an additional consideration when mapping 11073 units to HL7.HL7 OBX-2 defines the Value Type that is used to express the value in OBX-5 based onHL7 Table 0125.The PCD TF constrains the allowable value type to those shown in Table 8 PCDConstrained HL7 Table 0125Table 8 PCD Constrained HL7 Table 0125Value Description CommentCD Coded EntryCF Coded Element with Formatted ValuesDT DateED Encapsulated DataFT Formatted TextNM NumericPN Person NameRev. 1.1 TI: 2006-08-1529Copyright © 2005-2006: ACC, ACCE, HIMSS, and RSNA
