FQL is a query language that allows you to retrieve, filter and project data from any data source containing FHIR Resources. It brings the power of three existing languages together: SQL, JSON and FhirPath. It allows you to create tables and is useful for gaining insight and perform quality control.

Observation - HDDT Blood Pressure Value
Profile for capturing blood pressure value as FHIR Observation resources.
This profile defines the exchange of blood pressure value data for the Mandatory Interoperable Value (MIV) "Blood Pressure Monitoring" which is technically defined by the ValueSet hddt-miv-blood-pressure-value. This MIV is e.g. implemented by automated sphygmomanometers (oszillometric, auscultatory) that can connect to a Personal Health Gateway (e.g. a mobile app for tracking blood pressure values) through wireless communication.
Blood pressure measurements consist of multiple components: systolic blood pressure, diastolic blood pressure, and optionally mean blood pressure. This profile uses the LOINC panel code #85354-9 "Blood pressure panel with all children optional" defined in the MIV hddt-miv-blood-pressure-value to represent the complete measurement.
Obligations and Conventions:
Each Blood Pressure Measurement MUST hold a reference to a Personal Health Device Device resource. Blood pressure devices typically do not require calibration.
This profile inherits from the FHIR Blood Pressure profile (http://hl7.org/fhir/StructureDefinition/bp) and adds HDDT-specific constraints. The blood pressure components
(systolic and diastolic are mandatory; mean is optional) are inherited from the parent profile with the MeanBP component added as an optional slice.
Each component MUST include a value in mmHg (millimeters of mercury).
Caution: For privacy and data protection, the subject reference MUST only use pseudonymized or anonymized identifiers. Direct patient identification is not permitted.
