1 Definition

Physiological Signal Qualifier is a set of Data providing additional information on Physiological Signal Data for potential use by a machine.

The combination of Physiological Signal Data and Physiological Signal Qualifier is called Physiological Signal Object, specified by AIH-HSP V1.0.

2 Functional Requirements

Physiological Signal Qualifier must allow the expression of the following Elements:

  1. Sub-Type
  2. Format
  3. Attributes

Users needing additional entries in the Physiological Signal Qualifier or support of new Qualifiers should make a documented request to the MPAI Secretariat. Requests will be considered by the appropriate MPAI committee.
