4. IEEE P11073-10101b Events and Alerts
The existing list of ISO/IEEE :2004 MDC_EVT_ identifiers has been extended to support the IHE PCD Rosetta for Events and Alerts and ACM. This work extends the existing :2004 nomenclature with contributions from GE, Philips, Dräger and others.
Events and alerts will be included in IEEE P b , based on earlier discussions.
Physiologic events and alerts – largely done, with par-src-evt 3-tuples.
Technical events and alerts – 800+ proposed and existing REFIDs and definitions based on GE, Philips and :2004 standard, with more terms from Dräger and other vendors.
Preliminary par-src-evt 3-tuples for ecg, ecgResp, nbp, spO2, temp, ip, eeg, bis and entropy with proposed definitions - phys-tech.2d T20.ecg-ecgResp-nbp-spO2-temp-ip-eeg-bis-entropy.xlsx
Preliminary par-psrc-evt 3-tuples for resp, spiro, gasMonCO2 and gasMon with definitions has been completed; ventilators and anesthesia are next.

5. IEEE P11073-10101b par-src-evt 3-tuples
description
remarks
ecg-phys
MDC_ECG_HEART_RATE
MDC_EVT_LO MDC_EVT_HI
Heart rate limit exceeded
+ reuse of existing numeric identifiers + additional lo|high variants
MDC_ECG_V_P_C_CNT «VMD»
MDC_EVT_ECG_V_P_C_RonT
R-on-T PVC
’named’ event/alert fully identifies
– src is largely arbitrary and redundant
ecg-tech
MDC_ECG_LEAD_RA
MDC_ECG_LEAD_*
MDC_EVT_LEAD_DISCONN
Lead disconnected
+ src and evt convey useful information
vent-tech
Estimated leak flow rate ?
«VMD»
MDC_EVT_VENT_PAT_CIRCUIT_DISCONN
Patient circuit disconnected
’named’ event/alert fully identifies – src is unnecessary
Comments:
1. par-src-evt representation works reasonably well (par is typically required in most protocols).
2. src identifier is not consistently obvious if evt is already a strong standalone semantic concept.
Recommendations:
IEEE P b (or RTMMS) shall provide a full description with each par-src-evt 3-tuple.
Alternatively stated, one or more valid src values shall be specified with each event/alert term-row.
This is consistent with how many user and service manuals are written and would facilitate direct conversion of on-the-wire par-src-evt 3-tuples to text messages that could be displayed on the device.

6. IEEE P11073-10103a Implanted Devices Cardiac
Extends IEEE P :2012 Implanted Devices Cardiac
New IDC term codes, extending IEEE P :2012.
Notifications (‘alerts’) are largely complete with the definition of 14 standardized notification categories that convey publically- disclosed vendor-specific notifications. [This reflects the sometimes significant differences in the underlying vendor design of these devices.]
Several dozen new terms and term-sets have been reviewed by the Heart Rhythm Society (HRS) and will be included in the standard.
The IDCO WG meets weekly on Fridays at 10:00 AM Central (US).

7. Extras Additional UOM_MDC and UOM_UCUM for hRTM2a
Added to support vendor requests.
PHD vs RTMMS Code Conflict Detection
Semi-automatic identification of numeric code conflicts.
Provisional MDC_ATTR and MDC_EVT terms for WCM and MEM-LS
WCM and MEM-LS have numeric identifier codes, assigned as ‘provisional’ terms, described in the next presentation. Codes were used for data interchange at 2018 IHE NA Connectathon!
