ARCHETYPE IDopenEHR-EHR-OBSERVATION.tympanogram.v1
ConceptTympanogram Result
DescriptionRecord of measurements of movement at the tympanic membrane in response to changes in air pressure in the ear canal and their clinical interpretation as an indication of middle ear function.
UseUse to record movement of the tympanic membrane in response to various levels of air pressure, for a single ear at a time. Use to record the interpretation all measurements to infer middle ear function for each ear, plus an overall interpretation (or tympanometric diagnosis). All of the data elements are recorded using a single method or protocol. If, during the test, any of the protocol parameters need to be modified, then the subsequent part of the test will need to be recorded within a separate instance of the test data, using the updated protocol parameters.
MisuseNot to be used to record other hearing tests. Use other archetypes as appropriate, for example OBSERVATION.audiogram.
PurposeTo record measurements of movement at the tympanic membrane in response to changes in air pressure in the ear canal and to infer middle ear function.
