| Title | Haemodialysis Session Extraction |
| Description | One dialysis session out as: a Procedure for the session itself, coded to SNOMED 302497006, with the treatment time as its period and the access as a note; the pre-, target and post-dialysis weights each as their own Observation, because the nephrologist reads them against each other over weeks; the fluid actually removed as its own Observation; the prescription and the machine's function check as two panels, because neither of their parts means anything alone; and one Observation per timed reading through the run, each keeping the reading's own time, since the flow chart is a time series and the circuit pressures are what a run is judged on. |

"description": "One dialysis session out as: a Procedure for the session itself, coded to SNOMED 302497006, with the treatment time as its period and the access as a note; the pre-, target and post-dialysis weights each as their own Observation, because the nephrologist reads them against each other over weeks; the fluid actually removed as its own Observation; the prescription and the machine's function check as two panels, because neither of their parts means anything alone; and one Observation per timed reading through the run, each keeping the reading's own time, since the flow chart is a time series and the circuit pressures are what a run is judged on.",

The second copies the tenant tags off the\r\nresponse, because nothing else on the path puts them there.\r\nThe code is the form's document type, not the questionnaire's id: every\r\nenvironment mints its own ids, and there is only one set of maps, so an id\r\nhere would tie the tag to whichever environment stamped it.\r\n── Provenance and tenancy ───────────────────────────────────────────────────",
