| Active as of 2024-02-08 | Computable Name: MimicObservationVitalSigns | |||
An Observation resource (based on FHIR R4 Observation) that represents a single measurement from a row of the triage and vitalsign tables of MIMIC-ED: only pain, temperature, heartrate, resprate, blood pressure sbp dbp, and o2sat.
Usage:
Description of Profiles, Differentials, Snapshots and how the different presentations work.
