在一些 FHIR 资源中出现了一个 LOINC 概念 55284-4，例如： https ://syntheticmass.mitre.org/v1/fhir/Patient/0000aa42-c235-4447-8389-8a2640f44466/$everything
此代码用于“血压收缩压和舒张压”，位于 OMOP 概念表中，如下所示。
这个概念不是一个标准概念，不是一个有效的概念（从 OMOP 的角度来看），并且没有映射到 OMOP 中的任何标准概念。
这个概念出现在 FHIR 资源中，如下所示的片段（来自上面显示的合成器 url）。
应该在 OMOP 中创建哪些记录来表示如下所示的片段？

编辑：附加信息 看起来这些可能是 OMOP 中常用的血压概念
select
*
from
concept
where 1=1
and (
lower(concept_name) = 'systolic blood pressure' or
lower(concept_name) = 'diastolic blood pressure')
and domain_id = 'Measurement'
and standard_concept = 'S';
还有很多其他潜在的候选人（大约 380 人）：
select
*
from
concept
where 1=1
and lower(concept_name) like '%blood pressure%'
and domain_id = 'Measurement'
and standard_concept = 'S';
