BRTmessage code: what kind of message this is - MSH-9.2
O32trigger event: what happened in the real world: blood product transfusion/disposition acknowledgment - MSH-9.3
BRT_O32message structure: which segments to expect, and in what order

Message structures
BRT takes 1 structure.
BRT_O32: Blood Product Transfusion/Disposition Acknowledgment
Sent when one thing happens: O32: Blood Product Transfusion/Disposition Acknowledgment.
You must always send: MSH, MSA. Everything else is optional, or required only inside a group you chose to send.
| Segment | Name | OPT | Cardinality |
|---|---|---|---|
| MSH | Message Header | R | 1..1 |
| MSA | Message Acknowledgment | R | 1..1 |
| ERR | Error | O | 0..* |
| SFT | Software | O | 0..* |
| NTE | Notes and Comments (for Response Header) | O | 0..* |
| RESPONSE | a group of 2 segments, repeated together | O | 0..1 |
| PIDin RESPONSE | Patient Identification | O | 0..1 |
| ORDERin RESPONSE | a group of 4 segments, repeated together | O | 0..* |
| ORCin ORDER | Common Order | R | 1..1 |
| TIMINGin ORDER | a group of 2 segments, repeated together | O | 0..* |
| TQ1in TIMING | Timing/Quantity | R | 1..1 |
| TQ2in TIMING | Timing/Quantity Order Sequence | O | 0..* |
| BPOin ORDER | Blood Product Order | O | 0..1 |
| BTXin ORDER | Blood Product Transfusion/Disposition | O | 0..* |
R inside a group means required of that group. Send the group and you must include that segment; leave the group out and it never appears. This structure has 3 such groups: RESPONSE, ORDER, TIMING.
