| 0. Ratio | |
| Definition | A relationship of two Quantity values - expressed as a numerator and a denominator. |
| Short | A ratio of two Quantity values - a numerator and a denominator |
| Comments | The Ratio datatype should only be used to express a relationship of two numbers if the relationship cannot be suitably expressed using a Quantity and a common unit. Where the denominator value is known to be fixed to "1", Quantity should be used instead of Ratio. |
| Control | 0..* This element is affected by the following invariants: ele-1 |
| Is Modifier | false |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) rat-1: Numerator and denominator SHALL both be present, or both are absent. If both are absent, there SHALL be some extension present ( (numerator.empty() xor denominator.exists()) and (numerator.exists() or extension.exists()))rat-1: Numerator and denominator SHALL both be present, or both are absent. If both are absent, there SHALL be some extension present ((numerator.empty() xor denominator.exists()) and (numerator.exists() or extension.exists())) |
| 2. Ratio.numerator | |
| Definition | The comparator is not used on a SimpleQuantity The value of the numerator. |
| Short | A fixed quantity (no comparator)Numerator value |
| Comments | The context of use may frequently define what kind of quantity this is and therefore what kind of units can be used. The context of use may also restrict the values for the comparator. |
| Control | 10..1 This element is affected by the following invariants: ele-1 |
| Type | Quantity(CH Core Quantity with EMED Units) |
| Is Modifier | false |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) qty-3: If a code for the unit is present, the system SHALL also be present ( code.empty() or system.exists())sqty-1: The comparator is not used on a SimpleQuantity ( comparator.empty()) |
| 4. Ratio.denominator | |
| Definition | The comparator is not used on a SimpleQuantity The value of the denominator. |
| Short | A fixed quantity (no comparator)Denominator value |
| Comments | The context of use may frequently define what kind of quantity this is and therefore what kind of units can be used. The context of use may also restrict the values for the comparator. |

| 2. Ratio.id | |
| Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
| Short | Unique id for inter-element referencing |
| Control | 0..1 |
| Type | string |
| Is Modifier | false |
| XML Format | In the XML format, this property is represented as an attribute. |
| Summary | false |
| 4. Ratio.extension | |
| Definition | May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. |
| Short | Additional content defined by implementations |
| Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. |
| Control | 0..* |
| Type | Extension |
| Is Modifier | false |
| Summary | false |
| Alternate Names | extensions, user content |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))ext-1: Must have either extensions or value[x], not both ( extension.exists() != value.exists()) |
| Slicing | This element introduces a set of slices on Ratio.extension. The slices areUnordered and Open, and can be differentiated using the following discriminators: |
| 6. Ratio.numerator | |
| Definition | The comparator is not used on a SimpleQuantity |
| Short | A fixed quantity (no comparator) |
| Comments | The context of use may frequently define what kind of quantity this is and therefore what kind of units can be used. The context of use may also restrict the values for the comparator. |

| 8. Ratio.denominator | |
| Definition | The comparator is not used on a SimpleQuantity |
| Short | A fixed quantity (no comparator) |
| Comments | The context of use may frequently define what kind of quantity this is and therefore what kind of units can be used. The context of use may also restrict the values for the comparator. |
