SampledData

Base StructureDefinition for SampledData Type: A series of measurements taken by a device, with upper and lower limits. There may be more than one dimension in the data.

Schema

Elements

Name	Required	Type	Description
id		string	Unique id for inter-element referencing Details Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
extension		Extension[]	Additional content defined by implementations Details 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. 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.
origin	✓	Quantity	Zero value and units Details The base quantity that a measured value of zero represents. In addition, this provides the units of the entire measurement series.
period	✓	decimal	Number of milliseconds between samples Details The length of time between sampling times, measured in milliseconds. This is usually a whole number.
factor		decimal	Multiply data by this before adding to origin Details A correction factor that is applied to the sampled data points before they are added to the origin.
lowerLimit		decimal	Lower limit of detection Details The lower limit of detection of the measured points. This is needed if any of the data points have the value "L" (lower than detection limit).
upperLimit		decimal	Upper limit of detection Details The upper limit of detection of the measured points. This is needed if any of the data points have the value "U" (higher than detection limit).
dimensions	✓	positiveInt	Number of sample points at each time point Details The number of sample points at each time point. If this value is greater than one, then the dimensions will be interlaced - all the sample points for a point in time will be recorded at once. If there is more than one dimension, the code for the type of data will define the meaning of the dimensions (typically ECG data).
data		string	Decimal values with spaces, or "E" | "U" | "L" Details A series of data points which are decimal values separated by a single space (character u20). The special values "E" (error), "L" (below detection limit) and "U" (above detection limit) can also be used in place of a decimal value. Data may be missing if it is omitted for summarization purposes. In general, data is required for any actual use of a SampledData.
