Abstract

A method and apparatus of obtaining research data that includes a set of physiologic parameters of a subject by utilizing a physiologic sensor which measures a plurality of physiologic parameters of a subject by obtaining signals from the sensor from which the physiologic parameters are calculated and which verifies the calculated parameters with preset criteria, comprising the steps of: Providing a plurality of distinct error classification codes for the calculated parameters, wherein each error classification code is associated with a given set of failed criteria; Recording the calculated parameters of the subject over a session period; Assigning error classification codes to calculated parameters that failed to meet the given criteria; and Recording the assigned error codes in a time integrated manner with the calculated parameters of the subject over a session period. The Error codes may be visibly displayed to the user in a variety of formats.
