whether this record is complete (“F” for Final), is an edit/correction of an existing record (“C” for Correction), or if this record should be deleted
(“D” for Delete) and removed from the receiving system. The default value shall be “F”. This should be considered as future GE Healthcare
functionality that does not yet exist in the feeder/creation system, but that should be planned/designed for in future receiving systems.

Sequencing Rules
The OBR shall serve as the header segment for a particular observation set or phase.
Individual OBX segments shall serve as a single observation, observation fragment or a
reporting structure for similar groupings of observations (e.g. pressure measurement).
The OBX represents the smallest indivisible unit of a case report. For the purposes of the GE
Healthcare Mac-Lab/CardioLab data export, the OBR segment shall represent the separate
phases (GE Healthcare customers may use the term ‘condition’).
Examples of customer-named phases might include:
Baseline
Room Air
100% O2
PTCA
Intervention
Phases may be iterative. Each OBX segment, which is subordinate to an OBR, will represent
the clinical events that occurred under and during that particular phase.
OBX’s shall represent the events such as vital signs, administered drugs, pressures, valve
information, supplies, etc. that occurred while in that protocol.
Within a phase, events (OBX’s) shall be in chronological order.
NOTE: Phase naming conventions are user-defined within the Mac-Lab/CardioLab application.
Coordination may be necessary between GE Healthcare customer/clinical support and
the client to standardize their phase names and the conditions for their site’s use as
much as possible. This will ensure best alignment of the client’s data.
Segments Hierarchy
An example hierarchy of segments that creates a pseudo HL7 message follows:
NOTE: The OBR sequence numbers may change in the actual export, depending on:
Number of registry form nodes available in the study
Number of phases available
Number of case type available, etc.

Data Tables - Common / Raw Events Reporting Structures
These are the administrative observations and raw clinical values that are captured during the
course of a study. During any hemodynamic phase, a number of similar measurements can be
made (for example, multiple LV measurements). Generally, only one of these events is used to
compute hemodynamic analysis for that phase. The user, in order to synchronize for inclusion in
the study report, can select those events being reported here. A select, unique, phase-based
subset of these raw clinical events is reported in the Hemodynamic Measurement structures later
in this document. The values included in those Hemodynamic Measurement structures are
synchronized with other values in that section (e.g. a particular cardiac output reported in the
General Structure is the same one used in the Valve Pressure Structure irrespective of the raw
multiple cardiac outputs recorded in a hemodynamic phase) for clinical significance. The raw
Event-based clinical observations & measurements reported in this section should not be used
for hemodynamic analysis.

Event_Intervention OBXs
There are several OBX types tied to an Intervention: Lesion, Treatment, Attempt, Intervention
Supply and Graft. Each Treatment OBX will also include information about the Lesion to which
the treatment is being applied. Each Attempt OBX will include information about the treatment to
which the attempt is being made and the lesion to which the treatment is being applied. Each
Intervention Supply OBX will include information about the treatment and lesion with which the
supply is being used.

Cath Hemodynamic Measurement Reporting Structures
Mac-Lab can produce over 350 discrete clinical measurements. Although not all measurements
would be provided in a test, any combination can be present. The measurement values taken
during the study are stored in one of six (6) different formats/structures, depending upon the
content of the measurement. The structures and associated observations are listed below. The
formats of the measurement structures are fixed and are not user configurable.
The information reported in these Hemodynamic Measurement reporting structures are the
clinical values used for hemodynamic analysis. The values included in these structures are
synchronized with other values in this section (for example, a particular cardiac output reported in
the General Structure is the same one used in the computation of the Valve Pressure Structure
irrespective of the multiple raw cardiac output events recorded in a hemodynamic phase).

Source: Each measurement is flagged as to the source of the information. Generally, for all
measurements except for VO2, the source represents whether the value was Calculated or
Manually Entered. For VO2, it represents the specific algorithm used to derive the VO2 value
