title: An improved metabolic calibrator for stress test equipment: protocol for its clinical utilization.
abstract: In previous articles, the technical specifications, validation and clinical applicability of a new metabolic calibrator for stress test apparatuses were described. However no indication was given of a basic protocol for the current clinical practice. Here we present an organised check system to satisfy this aim. A method for the exhaustive evaluation of the technical reliability of the metabolic instruments is presented together with the proposal of a uniform simulation approach to organise checks on-line of the apparatuses' ability to follow correctly the various test phases (protocol). Examples of recordings of checks using the standardised approach are shown. The method seems to be very effective. Every operation is computer directed.
