Breathing apparatus for use in the investigation of the respiration mechanism of a respiratory system

摘要

A method is disclosed for examining the pulmonary mechanics of a respiratory system. In order to obtain information on the mechanical properties of the respiratory system's lungs, the method is devised to encompass steps, during an expiration, entailing at least modulation of a flow of gas (42A) streaming out of the respiratory system, determining the volume of gas streaming out of the respiratory system in relation to time, determining the variation in pressure in the respiratory system in relation to time and determining an expiratory pressure-volume relationship from the volume/time relationship and pressure/time relationship.
