- ReferenceRangeType

Profile: Shareable CodeSystem

This case-insensitive code system `http://hl7.org/fhir/uv/pocd/CodeSystem/reference-range-type` defines the following codes:

Code | Display | Definition
alarm-limits | Alarm limits | The range defines the alarm limits configured on the device. Values outside this range trigger an alert.
physiological-range | Physiological range | The range defines the physiologically normal or expected values for the measured parameter.
technical-range | Technical range | The range defines the technical measurement capability of the device — the minimum and maximum values the device can report.
