Apparatus for determination of recruitable volume of a lung

摘要

An apparatus (22) for determination of recruiatable volume in a lung is disclosed. A comprehension regarding the progress of a treatment and necessary measures is obtained by a control system connectable to a pneumatic unit (4) and to a measurement system (18A, 18B, 18C, 32) and adapted to perform the following method steps: at a first point of time regulate the pneumatic unit (4) to generate a first test breath having predetermined parameters with respect to flow and/or pressure of the gas flow, register volume and pressure in the lung during the first test breath, mesured by the measurement system (18A, 18B, 18C, 32), at a second point of time regulate the pneumatic unit (4) to generate a second test breath identical to the first test breath, register volume and pressure in the lung during the second test breath, measured by the measurement system (18A, 18B, 18C, 32), compare registered volume and pressure for the first test breath and the second test breath, and determine a recruaitable volume based on the comparison.
