Slices

This structure defines the following Slices:

• The element Observation.code.coding is sliced based on the values of value:code, value:system
• The element Observation.component is sliced based on the values of value:code.coding.code, value:code.coding.system
• The element Observation.component.code.coding is sliced based on the values of value:code, value:system

This indicates the differences between this profile and the base Observationvitalsigns structure.

Slices

This structure defines the following Slices:

• The element Observation.code.coding is sliced based on the values of value:code, value:system
• The element Observation.component is sliced based on the values of value:code.coding.code, value:code.coding.system
• The element Observation.component.code.coding is sliced based on the values of value:code, value:system

This provides the consolidated view (aka snapshot) of the profile after applying the changes in this profile to the base Observationvitalsigns structure.
