title: Evaluation of the Lung Ventilator Performance Analyser.
abstract: The characteristics of the Lung Ventilator Performance Analyser (LVPA) have been compared with the model lung defined in the proposed ISO standard for Breathing Machines. The different characteristics of the two models lead to marked differences in the pressure, flow and volume curves obtained during a standard procedure. The LVPA is a useful teaching tool, but it is recommended that ventilator testing should be performed on a lung model which fulfills the requirements of the proposed International Standard.
