This structure is derived from Observation

Summary

Mandatory: 2 elements
Fixed: 15 elements

Structures

This structure refers to these other structures:

• PupilDiameter (https://larfuma.github.io/fhir-eyecare-ig/StructureDefinition-pupil-diameter)

Slices

This structure defines the following Slices:

• The element 1 is sliced based on the value of Observation.hasMember (Closed)
• The element 1 is sliced based on the value of Observation.component
