ValueSet
Expansion performed internally based on codesystem QuantityComparator v6.0.0-ballot4 (CodeSystem)
This value set contains 6 concepts
| System | Code | Display | Definition |
http://hl7.org/fhir/quantity-comparator |
< | Less than | The actual value is less than the given value. |
http://hl7.org/fhir/quantity-comparator |
<= | Less or Equal to | The actual value is less than or equal to the given value. |
http://hl7.org/fhir/quantity-comparator |
>= | Greater or Equal to | The actual value is greater than or equal to the given value. |
http://hl7.org/fhir/quantity-comparator |
> | Greater than | The actual value is greater than the given value. |
http://hl7.org/fhir/quantity-comparator |
~ | Approximately | The actual value is approximately equal to the given value. A recommended value for the approximation is 10% of the stated value (or for a date, 10% of the gap between now and the date), but systems may choose other values where appropriate. Systems SHOULD use the Quantity Confidence Interval extension (http://hl7.org/fhir/StructureDefinition/quantity-confidenceInterval) to provide more detail when possible. |

ad | Sufficient to achieve this total quantity | The actual value is sufficient for the total quantity to equal the given value. |

Explanation of the columns that may appear on this page:
| Lvl | A few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information |
| Source | The source of the definition of the code (when the value set draws in codes defined elsewhere) |
| Code | The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract') |
| Display | The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application |
| Definition | An explanation of the meaning of the concept |
| Comments | Additional notes about how to use the code |
