| Concept | Waveform |
| Description | A waveform of an equidistant series of time spaced measurements e.g. from a pulse oximeter. |
| Use | Used within an OBSERVATION archetype e.g. OBSERVATION.heart_rate-pulse or OBSERVATION.indirect_oximetry. Details of the waveform start time and duration/interval should be stored in the parent OBSERVATION. May be used to assess the quality of a measurement, as using a pulse plesmythography waveform to assess the accuracy of a pulse oximetry SpO2 measurement. May also be used as part of a direct patient assessment, e.g. using a pulse plesmythography waveform for cardiac output estimation. |
| Misuse | Should not normally be used other than within an OBSERVATION archetype. |
| Purpose | To record a series of equidistant time-spaced observations that can be represented as a waveform e.g. a pulse plesmythography waveform from a pulse oximeter. |
